Precision Twist Drill QC91P taper length drills are available in a range of fractional and wire gauge diameters and are manufactured from High Speed steel, suitable for drilling in many materials including steel, stainless steel and aluminum. The bright finish prevents workpiece material from sticking to the cutting edges of the tool for a clean and accurate hole, whilst the 135 degree split point helps with self-centering for a rounder hole. With a specially designed parabolic flute, QC91P taper length drills can drill deeper holes in a single pass.
