Description
For low cost sheet metal holemaking. Blaircutters provide fast accurate burr-free holes in materials up to 3/16 Inch thick. Light-duty Blaircutters are annular cutting tools that cut around the edge of the hole and eject the center as a slug. Because theyre hollow theres no dead zone as with twist drills. 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 Inch and larger drill chucks. Spring loaded pilot "pops" the slug from the cutter.
