Precision Twist Drill R51 taper length drill bits are available in an extensive range of fractional sizes from 1/64 inch up to 1–3/4 inches. The bright finish prevents workpiece material from sticking to the cutting surfaces of the drill, giving cleaner, more accurate holes, whilst the conventional 118 degree point provides strength and easy re-grinding. Manufactured from High Speed Steel, the tools are suitable for drilling a variety of materials including steel, stainless steel and aluminum. R51 taper length series drills are recommended for drilling deeper holes and in applications where increased reach is required.
