The Precision Twist R08 jobber-length, black oxide finish, general-purpose, round-shank drill bit drills holes into a wide variety of metals and synthetic materials. It can drill to a depth up to four times the diameter of the drill size. The shank diameter is the same as the drill size. The R08 series has a type N flute form, with a regular helix (21 to 34 degrees) angle, with best performance drilling into steel, and cast iron. They are a common choice for general use applications. Spiral flutes act as a passageway for chip extraction from the hole and for coolant to enter the hole. Right-hand twist brings chips up and away from the cutting edge.
