Are of general purpose flute design but all sizes have a 1/2 by 2-1/4 long shank. The maximum overall length is 6 and the flute length is 3. This makes them short drills in the larger sizes and thus well suited to use in portable electric drills equipped with 1/2 chucks. They are highly effective in tough, high tensile strength materials. The 135 degree split point reduces thrust and eliminates walking at the drill point.

Broach cutting using PIP cutters means you can produce large diameter holes efficiently and quickly with less energy, faster penetration and less thrust. Rather than drilling out the metal with a solid drill, PIP cutters removes only the periphery of the hole, ejecting a slug at the end of the cut. Tests show that a solid drill will take 3 minutes, 45 seconds to drill a 1-1/4 inch hole in 3/4 inch plate. A PIP cutter can do the same job in 35 seconds. Packaging : All sizes are individually packaged.
