Product Description

The Precision Twist R10 jobber-length, uncoated bright 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 R10 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. Uncoated (bright) tools have no finish or coating. 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.

Drilling, or hole making, is the most common metalworking operation in the world. Twist drill bits are the most common type of drill bit used. Twist drill bits are commonly used to drill holes with hand-operated drills, standalone drill presses, or lathes. The flutes of the drill bit act a passageway for chip extraction from the hole and for coolant to enter the hole. These drill bits have a right-hand twist that brings chips up and away from the cutting edge. They are made to ANSI (fractional sizing) industry standards, which ensure that drill bits around the world conform to the same specifications.

Precision manufactures machine tools under the following brands: Precision Twist, Precision Dormer, and Union Butterfield. They have locations around the world, and provide tools adhering to ANSI, NAS, and DIN standards.
