It’s not easy to make a perfect instrument hole, but this tool will make it a snap. It’s a punch made out 4140 tool steel that has been hardened and precision ground to produce clean, flawless holes in aluminum up to 1/8” thick. Dual reversible design for punching both 2-1/4” and 3-1/8” holes. |
This Hole Punch works great, easily punches through tenth-inch aluminum for instrument panels. Makes nice, clean edge cuts.
