Troubleshooting
Punch is stuck in the hole
Ensure you are using the correct diameter punch; a 4mm punch is intended only for 4mm holes. Apply penetrating oil and tap lightly to loosen.
Punch head is deforming
Check your hammer weight. Using an excessively heavy hammer or one that is hardened steel rather than brass or rubber can damage the tool.

Setup, Compatibility & Care
To ensure the longevity of your Beta 31 Pin Punch, always match the punch size exactly to the diameter of the pin being removed. Avoid using the tool as a pry bar or screwdriver, as the tempered steel is designed for axial force rather than lateral stress. After use, wipe the punch clean of grease or oil to prevent rust, and store it in a dry tool chest. If the striking end develops a burr over time from repeated hammer blows, it can be carefully dressed down with a metal file to maintain a flat striking surface.
