Blair Spotweld Cutting Drilling kit
|
|
|
- This kit contains all the sizes of Blaircutter plus Arbor, & 3 Pilots in a sturdy case. For low cost sheet metal holemaking. Blaircutters provide fast, accurate, burr-free holes in materials up to 3/16" thick. Light-duty 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. Unlike hole saws, that rip and tear through the material, they quickly give you a quality, virtually burr-free hole. Spring loaded pilot "pops" the slug from the cutter.
Kit incluedes: 1/4", 5/16", 3/8", 7/16", 1/2", 9/16" and 5/8" Blaircutters. 1 arbor and 3 extra pilots.
