Drill Bits

Description : 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.
