The Greenlee Assembly Stud-Metal Punch can punch up through 20 gauge (0.9 mm) steel studs in one stroke.

Its ALUMINUM head provides strength, but with minimum weight, which reduces your fatigue.

The contoured handle gives better leverage and makes it possible to punch in tight places.

The self-stripping design eliminates punch hang-ups, and the punch automatically centres holes on standard studs.

There is a conversion kit available to upgrade early models from 24 gauge to 20 gauge maximum capacity.
