When you don’t have a lot of holes to make, Blaircutters™ 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.
