QC91G HSS TiN QC 135D Taper Length Drill Long ANSI N41 N41

QC91G taper length drills have a 135 degree split point for smooth self-centering, producing a rounder hole, and requiring less force to drill down. They are manufactured from High Speed steel and can be used to drill a wide range of materials including stainless steel, aluminum and steel, and have a titanium nitride coating which improves performance when drilling harder materials and promotes longer tool life. With a specially designed parabolic flute, the tools can be used to drill deeper holes in a single pass. QC91G taper length drills come in a wide range of wire gauge and fractional sizes.
