Frequently Asked Questions

Q: What is a roll pin punch used for?

A: A roll pin punch is a hand tool used to drive out (remove) or install roll pins — hollow, slotted cylindrical pins commonly found in machinery, firearms, watches, and automotive assemblies. It can also be used to mark drill hole centers and scribe lines on metal workpieces.

Q: What is the difference between buying 1 piece vs. the 6-piece set?

A: The single-piece option lets you select one specific head diameter (2mm, 3mm, 4mm, 5mm, 6mm, or 8mm) if you only need a particular size. The 6-piece set provides all six sizes (2–8mm) in one convenient package, making it the better value for workshop professionals or anyone who works across multiple pin sizes regularly.

Q: Are these punches suitable for watch repair?

A: Yes! The finer sizes (2mm and 3mm) are well suited for watch strap pin removal and small-scale precision work, while the larger sizes (5mm–8mm) are better matched to industrial machinery maintenance and manufacturing tasks.

Q: What material are the punches made from, and why does it matter?

A: These punches are made from heat-treated alloy steel, which gives them superior hardness and toughness compared to standard carbon steel tools. Heat treatment hardens the tip to withstand repeated hammer blows without deforming, chipping, or mushrooming — ensuring both safety and long service life.
