Description
Manufactured from premium High Speed steel for drilling many materials including steel, aluminum and stainless steel, R57 drills have a 1/2 inch parallel tri-flat shank which means you can hold large diameter drills in conventional hand-held power tools without any fears of slipping in the chuck. They have a conventional 118 degree point, making them easy to re-grind and use many times, and a steam oxide finish which prevents workpiece material from sticking to the cutting surfaces of the drill, so you get clean and accurate holes. R57 reduced tri-flat shank drills can be used in a range of different hand-held and machine applications.
