6palcový otvorový pilník Dozer z bimetalového materiálu s 3/8palcovým trnem a vodicím vrtákem

The arbor and pilot bit stay locked in tight—no wobble even after boring through a dozen holes in a row. I’m a contractor, and this thing’s life-time tooth warranty makes the clearance price feel like a steal.

Cut through drywall like butter—the Rip Guard teeth are still razor sharp after a dozen cuts. No binding or wandering, even on the first hole.

While the 3/8-inch arbor fit my drill perfectly out of the box, I was really impressed by how cleanly this bi-metal piece cut through an old steel door. For the clearance sale price, you get a seriously durable tool that I can see lasting through many more jobs.
