R56 drills have a reduced 1/2" parallel shank which means you can hold large diameter drills in conventional, hand-held power tools. Suitable for many different hand-held and machine applications, the drills are manufactured from High Speed steel and can be used for drilling many different materials including aluminum, stainless steel and steel. The steam oxide finish ensures accurate results by preventing workpiece material from sticking to the cutting surfaces of the drill, whilst the conventional 118 degree point provides strength and means the tools can be easily re-ground for use again and again.
