Product Description

The Precision Twist 2A jobber drill bit is a conventional point, general purpose, round shank drill bit made of HSS with an uncoated finish. It is suitable for drilling to a depth up to four times the diameter of the drill. It is used for handheld or machine drilling. The shank diameter is the same as the drill size. It was designed for drilling holes into a wide variety of metals and synthetic materials.

The 2A series has a type N flute form, with a regular (21- to 34-degree) helix angle, and performs best when drilling into steel or cast iron. The uncoated finish helps increase chip flow in soft materials. 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 can be used in hand-operated drills, standalone drill presses, or a lathe. They are made to DIN 338 industry standards, which ensure that drill bits around the world, confirm to the same specifications.

Together, the Precision Twist and Dormer brands represent a strong tool brand for high-productivity carbide and high-speed steel drill and tap products. Precision was founded in 1952 in Crystal Lake, IL. Dormer Tools, founded in 1913 in Sheffield, England, is known for innovative metalworking products.
