Broach cutting using Drill Bits World High Speed SteelFractional Size Annular Cutters 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, Drill Bits World 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 Drill Bits World cutter can do the same job in 35 seconds.
