When choosing a portable chain cutter, start with the largest chain-link material diameter you need to cut. Then confirm the chain material, grade, strength, heat treatment, link geometry, cutting-head access, power source, machine weight, blade availability and expected workload.
Chain diameter alone does not determine whether a cutter is suitable. Two chains with the same link diameter can require different cutting force when they use different alloys, grades or heat-treatment processes.
Choose a corded electro-hydraulic chain cutter when repetitive operation and reliable mains power are the priorities. Choose a cordless chain cutter when mobility, rapid deployment and operation away from convenient electrical outlets are more important.
The best portable chain cutter is the machine that safely matches the chain’s diameter, material strength, link geometry, cutting access and working environment.
What Is a Portable Chain Cutter?
A portable chain cutter is a compact powered tool designed to shear metal chain links directly at a construction site, maintenance area or field location.
Professional portable chain cutters are different from:
- bicycle chain breakers,
- small manual chain tools,
- pipe chain cutters,
- saw-chain repair tools,
- and jewelry chain cutters.
This guide focuses on powered metal-chain cutting equipment used in professional applications such as:
- construction and demolition,
- industrial maintenance,
- machinery servicing,
- utility and municipal work,
- infrastructure maintenance,
- equipment repair,
- and time-sensitive field operations.
POWER ELECTRICAL currently offers two professional electro-hydraulic chain-cutter platforms: the corded aluminum-body RD-10 and the cordless brushless RD-10B. Both are currently presented with a maximum rated chain diameter of up to 10 mm, although actual suitability also depends on chain material, hardness and construction.
How Does an Electro-Hydraulic Chain Cutter Work?
An electro-hydraulic chain cutter uses an electric motor to power a hydraulic system that moves the cutting blade through the chain link.
The basic energy path is:
Electrical Power → Motor → Hydraulic Pump → Hydraulic Pressure → Piston → Cutting Blade → Chain Shearing
The motor does not directly cut the chain.
Instead, it drives a hydraulic pump. The pump moves hydraulic oil, pressure develops when the blade encounters resistance, and that pressure acts on a piston. The piston then produces controlled linear movement at the cutting head.
A typical cutting cycle works like this:
- The operator identifies a suitable, unloaded chain link.
- The cutting head is positioned around the link.
- The trigger or switch activates the motor.
- The motor drives the hydraulic pump.
- Hydraulic pressure moves the piston.
- The moving blade advances toward the fixed blade.
- The link is sheared across its metal section.
- The blade retracts and the tool is repositioned.
The exact hydraulic circuit, blade-return mechanism and internal construction depend on the individual chain-cutter model.
What Should You Consider When Choosing a Portable Chain Cutter?
The most important buying factors are:
Chain diameter → material and strength → link geometry → cutting-head access → power source → workload → machine weight → blade availability
These specifications should be evaluated together rather than independently.
Maximum Chain Diameter
Maximum chain diameter normally refers to the thickness of the metal forming one link.
It does not usually mean:
- the outside width of the link,
- the overall length of the link,
- the inside opening,
- or the distance across two sides of the chain.
This distinction is important because measuring the outside dimensions of a link can produce a number much larger than the actual material diameter.
For example, a link made from 10 mm round steel will have an outside width substantially greater than 10 mm.
Use a caliper or micrometer to measure across the metal section of the link itself.
POWER ELECTRICAL currently lists both the RD-10 and RD-10B with a maximum rated chain diameter of up to 10 mm. The corded RD-10 product page also lists 110 V / 220 V power, approximately 8 kg net weight and an approximate 2-second cutting cycle under its published test conditions.
However:
A 10 mm diameter rating does not mean the cutter will automatically cut every 10 mm chain.
Material type, grade, heat treatment and hardness must also be considered.
Chain Material and Strength
Chain material directly affects cutting difficulty.
Metal chains may be manufactured from:
- mild steel,
- carbon steel,
- alloy steel,
- stainless steel,
- heat-treated steel,
- or other specialized materials.
A cutter that can shear a particular diameter of lower-strength carbon steel should not automatically be assumed to handle the same diameter of stronger heat-treated alloy chain.
The National Association of Chain Manufacturers publishes welded-steel chain specifications covering multiple chain grades and types, including Grade 30 proof coil, Grade 43 high test, Grade 70 transport, Grade 80 alloy and Grade 100 alloy chain. NACM also recommends consulting the chain manufacturer regarding the correct grade and specification.
For purchasing purposes, confirm:
Chain Diameter + Material + Grade + Heat Treatment + Cutter Rating
Chain Grade
Chain grade identifies a chain’s strength classification under the applicable specification or manufacturer system.
Different grades can have significantly different mechanical properties even when link diameter is identical.
This means:
Two 10 mm chains should not be treated as equivalent merely because their links have the same diameter.
Before selecting a cutter, identify the chain through:
- manufacturer markings,
- grade stamps,
- product documentation,
- material certificates,
- or technical confirmation from the chain supplier.
Do not guess a chain grade based only on appearance or coating color.
If the grade cannot be confirmed, obtain manufacturer guidance before attempting the cut.
Heat Treatment and Hardness
Heat treatment can substantially change the mechanical properties of a chain.
High-strength alloy and lifting chains may be heat treated to achieve higher strength than general-purpose chain of the same dimensions.
A harder material may:
- require greater cutting force,
- increase blade wear,
- reduce the cutter’s practical capacity,
- or fall outside the machine’s approved operating range.
Only use a portable chain cutter when the manufacturer confirms that the cutter is suitable for the chain’s material, strength and diameter.
Chain-Link Geometry
Chain links are not all shaped the same way.
Common differences include:
- round links,
- elongated links,
- short links,
- twisted links,
- welded links,
- narrow inside openings,
- and links positioned against nearby structures.
Link geometry affects whether the cutting head can be placed correctly around the metal section.
A cutter may have enough theoretical force but still be unsuitable when:
- the blades cannot reach the link,
- the cutting head cannot close correctly,
- the link cannot sit in the designed cutting position,
- or adjacent links obstruct the tool.
Capacity is therefore both a force question and an access question.
Cutting-Head Access and Clearance
Cutting-head access is one of the most important chain-cutter specifications to evaluate in real applications.
Before buying, consider:
- the opening of the cutting head,
- the size of the blade area,
- clearance around the target link,
- nearby machinery or structural components,
- chain position,
- and the operator’s ability to support the machine.
A 10 mm link in an open work area may be straightforward to position.
The same link inside a confined machine assembly may be inaccessible.
A cutter’s rated capacity has little practical value if the cutting head cannot physically reach and seat around the chain link.
Corded vs. Cordless Power
Choose corded or cordless power according to the working environment rather than assuming one platform is universally better.
Corded Chain Cutter
Choose a corded model when:
- reliable mains electricity is available,
- cutting is performed repeatedly,
- the machine stays near one working area,
- battery charging would be inconvenient,
- and continuous power is a priority.
The POWER ELECTRICAL RD-10 is currently offered as a corded aluminum-body chain cutter for 110 V or 220 V power.
Cordless Chain Cutter
Choose a cordless model when:
- operators move frequently,
- the worksite is remote,
- electrical outlets are inconvenient,
- extension cords would restrict access,
- elevated or field work is involved,
- or rapid deployment is important.
The RD-10B is currently presented as a 21 V brushless battery-powered chain cutter intended for mobile operation without external mains power.
Cutting Speed
Cutting speed matters when several chains must be removed or processed during one shift.
However, cutting-cycle numbers should always be evaluated with:
- chain diameter,
- material strength,
- link geometry,
- blade condition,
- and the manufacturer’s test conditions.
A fast published cycle on a compatible lower-strength chain does not establish the same performance on every chain type.
The RD-10 product page currently lists an approximate 2-second cutting cycle under its published operating conditions.
Machine Weight and Portability
A portable chain cutter should provide enough capacity without adding unnecessary weight.
Machine weight affects:
- transport between work areas,
- vehicle loading,
- elevated work,
- utility servicing,
- positioning around machinery,
- and operator fatigue.
The corded RD-10 is currently listed at approximately 8 kg net weight. The cordless platform eliminates the power cable but includes a battery, so buyers should compare complete operating weight rather than machine-only weight.
Do not automatically buy the largest available cutter when nearly all work involves smaller chains.
Hydraulic System
The hydraulic system converts motor power into linear blade movement.
A typical electro-hydraulic system may contain:
- electric or brushless motor,
- hydraulic pump,
- hydraulic oil,
- oil reservoir,
- cylinder,
- piston,
- seals,
- valves,
- and return components.
Buyers should evaluate the complete system rather than comparing motor wattage alone.
Motor power does not by itself establish:
- chain capacity,
- cutting force,
- durability,
- or suitability for hardened materials.
The cutting head, piston, hydraulic circuit, machine structure and blades all work together.
Cutting Blades
The blades are critical wear components.
A professional chain cutter may use:
- a moving blade,
- a fixed blade,
- blade bolts,
- guides,
- and supporting cutting-head components.
Blade life depends on:
- chain material,
- hardness,
- diameter,
- heat treatment,
- cutting frequency,
- positioning,
- alignment,
- and whether the cutter is used within its rated capacity.
There is no universal number of cuts that applies to every blade.
Before purchasing a portable chain cutter, confirm:
- replacement-blade availability,
- blade replacement procedure,
- delivery time,
- price,
- and technical support.
Duty Cycle and Workload
A cutter used several times per month for equipment maintenance has different requirements from one used repeatedly in a workshop or municipal service operation.
Estimate:
- cuts per day,
- typical chain diameter,
- largest diameter,
- material and grade,
- worksite access,
- power availability,
- and transportation frequency.
This helps prevent both underbuying and purchasing unnecessary capacity.
Spare Parts and Serviceability
A professional chain cutter should be evaluated as a serviceable machine rather than a disposable product.
Potential service parts include:
- moving blades,
- fixed blades,
- seals,
- switches,
- hydraulic components,
- motor parts,
- batteries,
- and chargers.
Replacement-blade availability is especially important because worn or damaged blades can reduce performance even when the hydraulic system remains functional.
Corded vs. Cordless Chain Cutters
| Factor | Corded Chain Cutter | Cordless Chain Cutter |
|---|---|---|
| Power Source | 110 V / 220 V mains power | Rechargeable battery |
| Mobility | Moderate | High |
| Continuous Operation | Strong with reliable power | Limited by available battery energy |
| Cable Management | Required | Not required |
| Setup | Requires nearby electrical supply | Fast field deployment |
| Remote Work | Less convenient | Strong advantage |
| Battery Management | Not required | Required |
| Typical Application | Fixed or repetitive work | Mobile and remote work |
| Best For | Continuous operation | Jobsite mobility |
Which One Should You Choose?
Choose a corded chain cutter when continuous operation and reliable electrical power are available.
Choose a cordless chain cutter when mobility, rapid deployment and freedom from external power are more important.
POWER ELECTRICAL currently positions the RD-10 for continuous corded operation and the RD-10B for cordless mobility; both platforms are presented with an up-to-10 mm rated chain capacity, subject to material suitability.
Hydraulic Chain Cutter vs. Bolt Cutter vs. Angle Grinder
A hydraulic chain cutter, bolt cutter and angle grinder can all be used for certain metal-cutting tasks, but they work in different ways.
| Factor | Hydraulic Chain Cutter | Bolt Cutter | Angle Grinder |
|---|---|---|---|
| Cutting Method | Powered shearing | Manual leverage and shearing | Abrasive grinding |
| Operator Effort | Low to moderate | High on larger material | Moderate |
| Power Source | Corded or battery | Manual | Corded or battery |
| Repetitive Work | Well suited within rating | Limited by operator effort | Application-dependent |
| Cutting Access | Requires cutting-head access | Requires jaw access | Requires wheel access |
| Grinding Sparks | Avoided | Avoided | Normally produced |
| Abrasive Dust | No abrasive-wheel dust | None | Produced |
| Consumable | Cutting blades | Jaws | Abrasive wheels |
| Noise | Model-dependent | Relatively low | Typically high |
| Best For | Professional powered chain cutting | Occasional smaller-chain cutting | Geometry inaccessible to shear tools |
Choose a Hydraulic Chain Cutter When
Choose a hydraulic chain cutter when:
- the chain is within rated diameter and material limits,
- powered shearing is preferred,
- repetitive or professional work is involved,
- manual bolt-cutting force would be impractical,
- and the cutting head can access the link.
Choose a Bolt Cutter When
Choose a bolt cutter when:
- the chain is within the manual tool’s capacity,
- work volume is low,
- electrical power is unavailable,
- portability must be extremely simple,
- and the operator can apply the required manual force safely.
Choose an Angle Grinder When
An angle grinder may be appropriate when:
- shear-style tool access is impossible,
- the chain geometry does not fit the cutter,
- the chain falls outside available hydraulic tooling,
- and abrasive cutting is permitted by the worksite procedure.
Angle grinders use abrasive wheels and require the correct guards, wheel condition and PPE. OSHA’s construction standard for abrasive wheels includes specific guarding requirements for grinding equipment and portable abrasive wheels.
A grinder should not be treated as the automatic solution merely because it can physically reach the chain.
Consider:
- sparks,
- abrasive debris,
- wheel condition,
- nearby combustible material,
- noise,
- and worksite authorization.
How to Measure Chain Diameter Correctly
Chain diameter is measured across the thickness of the metal forming one link, not across the overall outside width or length of the link.
Use a caliper or micrometer and follow these steps:
- Select a straight, accessible section of the link.
- Remove loose dirt or coating buildup that could affect the measurement.
- Measure across the round metal section.
- Repeat the measurement at more than one position.
- Record the largest consistent value.
- Identify the material grade and manufacturer marking separately.
Do not measure:
- across the link opening,
- from outside edge to outside edge,
- or across two adjacent links.
Diameter measurement is only the first step.
You must still identify:
- chain grade,
- material,
- heat treatment,
- link geometry,
- and cutting access.
How to Choose a Chain Cutter by Chain Diameter
A general selection framework is:
| Chain Requirement | Suggested Approach | Typical Application |
|---|---|---|
| Smaller general-purpose chain | Compact professional cutter rated for material | Maintenance and site work |
| Chain approaching maximum tool capacity | Verify material and manufacturer rating | Construction and industrial work |
| Heat-treated or high-strength chain | Obtain explicit manufacturer confirmation | Specialized service work |
| Unknown material or grade | Identify chain before cutting | Any professional application |
| Link inaccessible to cutting head | Select another approved method | Confined equipment or structures |
This framework is not a universal capacity guarantee.
POWER ELECTRICAL currently presents the RD-10 and RD-10B as up-to-10 mm chain cutters, but the company’s selection guidance also tells buyers to confirm chain material and hardness before choosing a model.
How to Choose a Portable Chain Cutter by Application
Construction and Demolition
Construction crews may need to remove:
- securing chains,
- temporary chain connections,
- damaged metal chains,
- or chain obstructions during renovation and demolition.
Best approach: Choose a portable cutter that matches the chain material and provides enough cutting-head clearance for the work area.
Never cut a chain while it is supporting a load or remains under uncontrolled tension. Isolate the area and unload the chain according to the applicable work procedure before cutting.
Industrial Maintenance
Industrial maintenance teams may remove worn, seized or damaged chains during machine servicing and equipment repair.
Best approach: Prioritize cutting-head access, portability, blade availability and serviceability.
A cordless cutter may improve mobility across a large plant, while a corded model may be more suitable at a fixed maintenance station.
Utility and Infrastructure Work
Utility, municipal and infrastructure teams often work across multiple field locations.
Best approach: Balance rated capacity with mobility, transport weight and power availability.
The cordless RD-10B is positioned for applications where rapid deployment and freedom from external power are important, while the corded RD-10 is intended for continuous operation where mains power is available.
Equipment Repair
Equipment repair may involve removing a damaged or obstructing chain before replacement.
Best approach: Check the available space around the target link before selecting the tool.
The chain may fall within the diameter rating but still be inaccessible because of:
- guards,
- shafts,
- housings,
- sprockets,
- or adjacent machine components.
Emergency and Time-Sensitive Field Work
Time-sensitive operations often prioritize rapid deployment and portability.
Best approach: Choose a cordless cutter when the machine’s rated material and diameter capacity are suitable.
Do not interpret fast deployment as permission to skip:
- chain identification,
- load isolation,
- work-area control,
- or manufacturer safety procedures.
Remote Jobsites
Remote sites may lack reliable mains electricity.
Best approach: Select a cordless chain cutter and plan sufficient batteries for the expected workload.
Battery planning should consider:
- number of cuts,
- chain material,
- temperature,
- charging access,
- and battery condition.
Do not assume a fixed number of cuts per battery unless the manufacturer provides test data for the relevant chain and operating conditions.
When Should You Choose a Portable Chain Cutter?
A portable chain cutter is usually the right choice when professional crews need controlled powered shearing directly at the work location and the chain is within the machine’s rated diameter and material range.
Typical situations include:
- repeated field maintenance,
- construction and demolition,
- utility servicing,
- machinery repair,
- remote work,
- and applications where manual bolt cutting is impractical.
A portable chain cutter is especially useful when transporting the chain to a stationary machine would be difficult or impossible.
When Should You Use Another Cutting Method?
Use another approved cutting method when the chain material, strength, diameter, geometry or access falls outside the portable cutter’s rated operating range.
Another method may be required when:
- the chain is too large,
- the chain grade is unknown,
- the chain is harder than the cutter is rated for,
- the cutting head cannot access the link,
- the link cannot be positioned correctly,
- the chain is still carrying a load,
- or the manufacturer does not approve the material.
Do not attempt repeated cuts on unsuitable material simply because the motor operates or the blade begins to move.
What Determines Chain-Cutting Capacity?
| Factor | Why It Matters |
|---|---|
| Chain Diameter | Determines the material cross-section |
| Material Type | Different metals resist shearing differently |
| Chain Grade | Indicates strength classification |
| Heat Treatment | Can increase hardness and strength |
| Link Geometry | Affects positioning and blade access |
| Cutting-Head Clearance | Determines whether the tool can reach the link |
| Hydraulic Output | Contributes to available blade force |
| Blade Condition | Worn blades increase cutting resistance |
| Blade Alignment | Incorrect alignment affects load and cut quality |
| Machine Structure | Supports the cutting forces |
| Correct Positioning | Keeps the link within the designed cutting area |
The central conclusion is:
Chain-cutting capacity is a combination of material, geometry, tooling and machine design—not a single diameter number.
What Affects the Price of a Portable Chain Cutter?
The price of a professional chain cutter can be influenced by several factors.
Rated Capacity
Larger or stronger chain normally requires a more robust cutting head, blades and hydraulic system.
Corded vs. Cordless Design
Cordless models include:
- battery packs,
- chargers,
- battery-management electronics,
- and typically a brushless motor platform.
Hydraulic System
Pump, cylinder, piston, seals and valve quality affect manufacturing cost and serviceability.
Machine Construction
Housing and structural materials influence:
- machine weight,
- portability,
- durability,
- and production cost.
Blade Design
Blade material, geometry and replacement availability affect both purchase price and long-term ownership cost.
Included Accessories
Packages may differ in:
- blades,
- batteries,
- chargers,
- carrying or storage cases,
- tools,
- and spare parts.
Manufacturer Support
Technical documentation, troubleshooting support, replacement parts and warranty service have real economic value for professional users.
The lowest purchase price does not necessarily produce the lowest total cost of ownership.

Common Mistakes When Buying a Chain Cutter
Mistake 1: Choosing Only by Chain Diameter
Diameter does not fully describe chain strength.
Material, grade and heat treatment also matter.
Mistake 2: Measuring the Outside Width of the Link
The relevant dimension is normally the thickness of the metal forming the link.
Using overall link width can lead to incorrect machine selection.
Mistake 3: Ignoring Chain Grade
A general-purpose chain and a heat-treated alloy chain can create very different cutting demands.
Mistake 4: Assuming Every Chain of the Same Diameter Cuts the Same Way
Identical dimensions do not guarantee identical mechanical properties.
Mistake 5: Ignoring Cutting-Head Access
The cutter can only work when the link fits correctly inside the cutting area.
Mistake 6: Cutting a Loaded or Uncontrolled Chain
A loaded or tensioned chain can move suddenly when severed.
The chain must be unloaded, isolated and controlled before cutting.
Mistake 7: Choosing Cordless Without Planning Battery Demand
Cordless mobility is useful, but sufficient charged batteries must be available for the real workload.
Mistake 8: Ignoring Replacement Blades
Blade availability should be confirmed before purchasing the machine.
Mistake 9: Buying Excessive Capacity
Unnecessary capacity can add weight and cost without improving everyday productivity.
Mistake 10: Comparing Only Purchase Price
A lower-cost machine can become expensive if blades, batteries or service parts are difficult to obtain.
Frequently Asked Questions About Portable Chain Cutters
What is a portable chain cutter?
A portable chain cutter is a compact powered tool designed to shear compatible metal chain links directly at a worksite or maintenance location.
Professional electro-hydraulic models use an electric motor and hydraulic system to generate controlled linear blade movement.
How does a hydraulic chain cutter work?
A motor drives a hydraulic pump, pressure acts on a piston, and the piston moves the cutting blade through the chain link.
The motor supplies energy, while the hydraulic system produces the linear cutting action.
How do I measure chain diameter?
Measure across the thickness of the metal forming one chain link.
Do not measure the outside width, inside opening or overall link length. Use a caliper or micrometer and also identify the chain material and grade.
What types of metal chain can a portable chain cutter cut?
It depends on the cutter’s rated capacity and the chain’s diameter, material, grade, hardness, heat treatment and geometry.
Do not assume one cutter can handle every steel chain of the same diameter.
Does chain grade affect cutting capacity?
Yes.
Chain grade relates to material strength, and stronger or heat-treated chain can require greater cutting force than lower-grade chain with the same dimensions. NACM specifications cover multiple welded-steel chain grades and recommend consulting chain manufacturers regarding grade and application.
Can a portable chain cutter cut lifting chain?
It depends on the lifting chain’s diameter, alloy, grade, heat treatment and the cutter’s manufacturer-rated capacity.
A lifting chain must never be cut while it is supporting a load. Unload and isolate it before any cutting procedure.
Can a chain cutter cut heat-treated alloy chain?
Only when the specific cutter is explicitly rated for that material, hardness and diameter.
Do not infer heat-treated alloy capacity from a general carbon-steel diameter rating.
Is a hydraulic chain cutter better than a bolt cutter?
A hydraulic cutter is generally more suitable for repetitive professional work or chains that would require excessive manual effort.
A bolt cutter may be more practical for occasional work on smaller compatible chain where powered equipment is unnecessary.
Is a hydraulic chain cutter better than an angle grinder?
A hydraulic cutter is often preferable when powered shearing is suitable and the cutting head can access the link.
An angle grinder may provide more flexible access, but it uses an abrasive wheel and normally produces grinding sparks and abrasive debris. OSHA requires appropriate guards for abrasive-wheel equipment.
Should I choose a corded or cordless chain cutter?
Choose corded when reliable mains power and continuous operation are priorities.
Choose cordless when mobility, rapid deployment and remote operation matter more. POWER ELECTRICAL currently offers the corded RD-10 and cordless RD-10B for these two different power requirements.
How long do chain-cutter blades last?
There is no universal blade-life figure.
Service life depends on chain hardness, grade, diameter, cutting frequency, blade alignment, positioning and whether the cutter is operated within its rated capacity.
Can a chain cutter be used on a chain under tension?
No uncontrolled or load-bearing chain should be cut.
Unload, isolate and restrain the chain according to the worksite procedure and equipment instructions before cutting.
How do I maintain a hydraulic chain cutter?
Typical maintenance includes inspecting the blades, cutting head, fasteners, hydraulic system, power cable or battery, and checking for leakage or abnormal wear.
Disconnect mains power or remove the battery before blade replacement or maintenance where accidental operation could create a hazard.
What affects the price of a portable chain cutter?
Rated capacity, power source, hydraulic construction, machine weight, blade design, included batteries, spare parts and manufacturer support can all affect price.
Professional buyers should compare total ownership cost rather than purchase price alone.
For buyers comparing other powered metal-cutting equipment, see our How to Choose a Portable Rebar Cutter guide for information about steel capacity, power source and jobsite portability.
Final Buying Recommendation
The correct portable chain cutter depends on the actual chain and working environment rather than diameter alone.
General Contractors
Choose a professional chain cutter rated for the real chain diameter, material and grade used onsite.
A compact corded or cordless platform may reduce manual effort during construction and demolition work.
Industrial Maintenance Teams
Prioritize:
cutting-head access + blade availability + serviceability
Maintenance chains are often located close to machinery, so access may matter more than maximum capacity.
Utility and Municipal Crews
Prioritize portability, rapid positioning and reliable field operation.
A cordless cutter can be practical where crews frequently move between service locations.
Mobile Field Crews
Choose a cordless chain cutter when the machine’s rated material and diameter capacity are sufficient.
Plan battery quantity according to workload.
Fixed Workshops
Choose a corded chain cutter when reliable 110 V or 220 V power is available and continuous operation is more important than maximum mobility.
Tool Distributors
Offer both corded and cordless platforms rather than presenting one machine as a universal solution.
POWER ELECTRICAL currently offers the corded RD-10 aluminum chain cutter and the cordless brushless RD-10B. Both are presented with up-to-10 mm rated chain capacity, while their primary difference is continuous mains power versus cordless jobsite mobility. POWER ELECTRICAL has specialized in professional portable electro-hydraulic tools since 2001.
The final buying rule is:
The best portable chain cutter is not necessarily the machine with the largest stated diameter. It is the machine that safely matches the chain material, strength, diameter, link geometry, cutting access, workload and working environment.
