Blair 13200 Cutter

When you don't have a lot of holes to make, BlaircuttersTM provide fast, accurate holes in materials up to 3/16 thick. Blaircutters are annular cutting tools that cut around the edge of the hole and eject the center as a slug. Because they're hollow there's no dead zone as with twist drills. And unlike hole saws, that rip and tear through the material, they quickly give you a quality, virtually burr-free hole. Blaircutters are available in seven sizes for 1/4 and larger drill chucks. Spring loaded pilot "pops" the slug from the cutter.
