DISCUSS YOUR APPLICATIONIS THE MHP-20B RIGHT FOR YOU?
Choose the MHP-20B when you need cordless mobility and your required hole diameter and material thickness are within its specified capacity. Confirm your material grade, tooling and battery configuration before ordering.
Choose the MHP-20B if you need:
- Holes within the 6–20.5 mm punching diameter range
- Material thickness up to 6 mm / 0.24 in.
- Approximately 3-second punching time
- 21 V DC cordless hydraulic power for mobile work
- Approximately 180 punches per charge, depending on application
- Standard mold diameters of 6.5, 9, 13, 17 and 20.5 mm
Your application needs a different capacity or power configuration
- You require holes outside the 6–20.5 mm diameter range
- Your material thickness exceeds 6 mm
- You prefer a corded tool for extended work where mains power is available
- You require slots or other hole shapes beyond the listed round molds
- Your workpiece geometry prevents correct positioning of the punch and die
- You need suitability confirmed for a particular material grade or strength
MHP-20B MOLD SIZE GUIDE
The MHP-20B has a specified punching diameter range of 6–20.5 mm. The five standard mold hole diameters are listed below; the smallest standard mold is 6.5 mm. If you need a 6 mm hole, confirm tooling availability before ordering.
| Mold Option | Hole Diameter | Imperial Diameter | Tooling | Selection |
|---|---|---|---|---|
| Size 1 | 6.5 mm | 0.26 in. | Matched punch & die | For a 6.5 mm round hole |
| Size 2 | 9 mm | 0.35 in. | Matched punch & die | For a 9 mm round hole |
| Size 3 | 13 mm | 0.51 in. | Matched punch & die | For a 13 mm round hole |
| Size 4 | 17 mm | 0.67 in. | Matched punch & die | For a 17 mm round hole |
| Size 5 | 20.5 mm | 0.81 in. | Matched punch & die | For a 20.5 mm round hole |
Selection rule: choose the mold by the required hole diameter, then confirm material grade and thickness. The specified maximum hole diameter is 20.5 mm and maximum thickness is 6 mm. Always use compatible, matched tooling.
