7/8" 초경 팁 홀쏘 7/8" TcT 홀쏘 커터 드릴 비트 7/8 Drill Hog USA

Bought this to punch a clean hole through some 3/4" plywood shelving and it cut through like butter with zero tear-out on the backside. The flange stops you from drilling too deep, which saved me from ruining a panel. Chuck held it steady the whole way and the hole was dead-on 7/8".

The carbide tips cut through my door slab way better than the bi-metal saw I used last time, and the flange kept me from punching through the backside. Only gripe is it wandered a bit on the first hole until I got the pilot bit seated, but after that it was clean.

Bought this for running conduit and it cuts clean holes without the burrs my old bi-metal saw left behind. The carbide tips are still sharp after maybe twenty holes in plywood. Only gripe is the pilot bit wanders a little on smooth surfaces.
