Set of 4 Knockout Punch Set for Cutting Holes

This FROST Knockout Punch Set is a quick and easy way to cut clean holes in Sheet Metal, Fiberglass and Plastic and comes presented in a solid metal Tool Box.

The special design produces a Burr Free Hole that needs no extra finishing.

A pilot hole is drilled allowing a connecting bolt to join the punch on one side and the die on the other side of the material. Pressure is then applied by tightening the bolt, (with a thrust washer for ease), thus the hole is literally punched out.
