Product Information
Full details
This Q.Max 18.6mm Sheet Metal Punch is designed for professionals and DIYers needing to create clean, metric-sized holes in sheet metal up to 16 gauge. Its key benefit is producing burr-free holes that require no extra finishing, saving time on assembly. A caveat to note is that the punch is sold separately from the necessary hexagonal key and may have a different assembly configuration for sizes 15mm and larger.

FAQs
What is the maximum thickness of sheet metal this punch can cut?
This punch is designed for sheet metal up to 16 gauge, which is approximately 1.5mm thick.
Do I need to buy the hexagonal key separately?
Yes, all punches are sold singly without the hexagonal key, which must be ordered separately.
What does 'burr-free hole' mean for the user?
A burr-free hole means the edge of the cut hole is smooth and clean, without any sharp or ragged metal protrusions. This eliminates the need for extra finishing steps like filing or sanding, saving time and effort.
How does the setup differ for larger punches (15mm and over)?
For punches 15mm and over, the thread is integrated directly into the punch itself. This means there are fewer components, as you do not need a separate die nut in the same way as smaller sizes.
How should I maintain the punch to prevent rust?
After each use, clean off any metal debris and ensure the punch is dry. Store it in a dry environment. The anti-corrosive finish helps, but periodic light oiling can further protect it.
Can this tool be used on materials other than sheet metal?
This punch is specifically designed for cutting clean holes in sheet metal up to 16 gauge. It is not intended for use on thicker metals, hardwoods, plastics, or other materials.
Troubleshooting
Punch not cutting cleanly
Ensure the sheet metal is within the 16-gauge limit. Check for dullness on the cutting edges and replace if necessary. Verify that the punch and die are properly aligned.
Difficulty turning the hexagonal screw
Confirm the die nut is properly threaded onto the hexagonal screw and is making contact with the metal. Ensure the hexagonal key is fully engaged with the screw head. Lubrication on the screw threads might help.
Punch gets stuck during operation
Remove the punch and inspect for debris or damage. Ensure the pilot hole is adequately sized for the punch. If punching thicker material than recommended, the tool may bind.
Tool shows signs of rust
Clean the tool thoroughly and dry it completely. Apply a light coat of oil to the metal surfaces. Store the tool in a dry location.

Setup, Compatibility & Care
Setup:
For punches up to 15mm:
- Thread the punch onto the hexagonal screw.
- Pass the hexagonal screw through the hole to be punched.
- Place the die on the die nut.
- Screw the die nut onto the hexagonal screw until it contacts the metal sheet.
- Use a hexagonal key to turn the hexagonal screw, pulling the punch through the metal.
For punches 15mm and over:
- Thread the punch (which has an integrated thread) onto the hexagonal screw.
- Pass the hexagonal screw through the hole to be punched.
- Place the die onto the punch.
- Screw the die nut onto the hexagonal screw until it contacts the metal sheet.
- Use a hexagonal key to turn the hexagonal screw, pulling the punch through the metal.
Compatibility:
- Designed for sheet metal up to 16 gauge (approximately 1.5mm thickness).
- Requires a compatible hexagonal key (sold separately).
Care:
- After use, clean any metal debris from the punch and die.
- Wipe dry to prevent rust.
- The anti-corrosive surface finish offers protection, but storing in a dry environment is recommended.
- Periodically check cutting edges for wear.
