Feedback Help us improve our product information


The Precision Twist R42C stub-length, medium duty drill bit is a round shank bit made of HSS with a steam tempering finish. It is suitable for drilling to a depth up to two-and-a-half times the diameter of the drill. The shank diameter is the same as the drill size. For best performance, use for drilling into steel, free machining stainless steel, titanium, and unalloyed nickel. The R42C series was designed for the aircraft industry, but also works well for drilling into a variety of materials. The short length and 135-degree split-point drill geometry provide extra rigidity and ensure a more accurate hole by reducing walking when the hole is started. The finish retains lubricant to aid in wear resistance and chip flow. The Precision Twist R42C series has a type N flute form, with a regular helix angle of 21 to 34 degrees. The steam tempering finish gives a strongly adhering blue oxide surface that acts to retain cutting fluid and prevent chip to tool welding, reducing the formation of a built-up edge. Spiral flutes act as a passageway for chip extraction from the hole and for coolant to enter the hole. and away from the cutting edge. They are made to ANSI (fractional sizing) and NAS 907 type C industry standards, which help ensure that drill bits around the world conform to the same specifications.
