Features and Benefits: * Size: 1/4" * Includes 3 in a pack * Spring loaded pilot “pops” the slug from the cutter * Low cost sheet metal hole making * Made in the USA 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.
