Full details
The Powertec Oblong Hole Punch (91250) is an essential tool for automotive body technicians and DIY fabricators who require efficient, clean-cut holes for panel repairs and welding preparation. By creating precise 6mm x 20mm openings, it eliminates the need for slow, imprecise drilling, though it is specifically optimized for thin-gauge sheet metal rather than heavy-duty structural steel.

FAQs
Can I use this on stainless steel?
It is designed for standard automotive body sheet metal; using it on hardened or thicker stainless steel may damage the punch.
What is the maximum hole size I can create?
This model creates a fixed 6mm x 20mm oblong hole.
Does this tool require air pressure?
No, this is a manual hand tool designed for portable use.
Is the punch head replaceable?
The tool is a high-quality unit designed for long service life; however, if the head becomes dull, check for Powertec replacement parts matching model 91250.
What is the primary benefit of the oblong shape?
The oblong shape provides "wiggle room" for panel alignment, which is critical when fitting replacement automotive body panels.
Troubleshooting
Punch is not cutting through the metal cleanly.
Ensure the sheet metal thickness is within the recommended automotive range and verify the punch head is properly aligned.
Tool feels stiff or difficult to operate.
Clean any metal shavings from the head and apply a small amount of lubricant to the pivot points.
Pros and Cons

Setup, Compatibility & Care
To ensure the longevity of your punch, always ensure the metal surface is free of heavy rust or debris before engagement. Align the tool perpendicular to the surface of the sheet metal to ensure the punch seats correctly.
Care Instructions
- Lubrication: Periodically apply a light coating of machine oil to the punch mechanism to ensure smooth operation.
- Storage: Keep the tool in a dry environment to prevent corrosion.
- Inspection: Regularly check the punch head for chips or dullness, as using a damaged head can result in ragged edges.
