Precision Twist Drill R40 screw machine length drills have a 118 degree conventional point for easy re-grinding so the drills can be re-used many times. They are manufactured from High Speed steel for drilling many materials including steel, stainless steel and aluminum, and come with a bright finish to prevent workpiece material from sticking to the cutting edges of the tool, so you get a cleaner more accurate hole (sizes 45/64 and above are steam oxide). There is a huge range of drills available, from 3/64 inch all the way up to 2 inches and for added versatility, the drills can be used in both machine and hand held applications. Please see R41 and R42 drills for matching drills in wire gauge and letter diameters respectively.
