Product Information
Full details
This Q.Max Sheet Metal Punch (70mm, ME key type) is designed for professionals who need to create clean, precise 70.0mm metric holes in sheet metal up to 16 gauge. Its special design ensures even load distribution during cutting, producing a burr-free hole that requires no secondary finishing, saving valuable time on the job. A potential caveat is that assembly instructions vary for punches 15mm and larger, requiring attention to the specific model's configuration.

FAQs
What size hole does this punch create?
This specific model creates a 70.0mm metric sized hole.
What is the maximum material thickness this punch can handle?
It is designed for sheet metal up to 16 gauge thickness.
Is the hexagonal wrench included?
No, the 14mm hexagonal wrench required for operation must be ordered separately.
Do I need to do any finishing after cutting?
The special design of this punch produces a burr-free hole that typically needs no extra finishing.
How do I maintain the punch for longevity?
Keep the cutting edges clean, lubricate the screw threads periodically, and store in a dry environment. Inspect for wear.
Are the setup instructions the same for all Q.Max punches?
No, instructions differ for cutters 15mm and larger. Larger cutters may have fewer components, with the thread directly in the punch and no die nut.
Troubleshooting
Punch not cutting cleanly or is difficult to turn.
Ensure the punch is properly aligned, the sheet metal is within the 16-gauge limit, and the hexagonal screw and die are clean and lightly lubricated. Check for damage to the cutting edges.
Hole has excessive burrs.
Verify that the correct punch size is being used for the material thickness. Ensure the cutting edges are sharp and not worn. The design aims for minimal burrs, so significant burrs may indicate a worn tool.
Difficulty threading the die nut.
Clean the threads on both the hexagonal screw and the die nut. Ensure they are not cross-threaded. A small amount of lubricant can ease the process.
Pros and Cons
Pros
- Produces clean, precise metric holes.
- Reduces post-cutting finishing work.
- Designed for durability and longevity.
- Suitable for up to 16-gauge sheet metal.
Cons
- Hexagonal key (14mm) is not included and must be purchased separately.
- Assembly instructions differ for punches 15mm and larger.
- Limited to 16-gauge sheet metal thickness.
Setup, Compatibility & Care
**Setup (Cutters up to 15mm):
- Thread the punch onto the hexagonal screw.
- Pass the hexagonal screw through the desired hole location.
- Position the die on top of the die nut.
- Screw the die nut onto the projecting hexagonal screw until it contacts the metal sheet.
- Use a 14mm hexagonal key to turn the hexagonal screw. The screw will pull the punch through the metal, creating a hole.
Note: For cutters 15mm and larger, the configuration is different; the thread is often in the punch itself, and a die nut may not be present. Refer to specific instructions for larger models.
Compatibility:
- Designed for metric sized holes.
- Suitable for sheet metal up to 16 gauge thickness.
- Requires a 14mm hexagonal wrench (sold separately).
Care:
- Keep cutting edges clean and free from debris.
- Apply a light lubricant to the screw threads periodically.
- Store in a dry place to prevent rust, though the anti-corrosive finish offers protection.
- Inspect cutting edges for wear and replace if necessary.
