What materials can this punch through?

Works on sheet metal, plastic trim, rubber gaskets, and similar automotive materials. Test on scrap material first if you're punching something unusual.

Do I need to prep the surface before punching?

Mark your hole location with a marker or tape to keep things precise. Clean any debris or rust off the spot you're punching — a quick wipe keeps the tool working smoothly.

What if one of the punch heads wears out or breaks?

Replacement punch heads are available separately. Contact customer service with your tool serial number to order the specific size you need.
