Includes 1/4", 5/16", 3/8", 7/16", 1/2", 9/16" and 5/8" cutters, arbor and 3 extra pilots. 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. Spring loaded pilot "pops" the slug from the cutter. Packaged in a blow molded case.
