Precision Twist Drill 5ATL23.0 5ATL Taper Length Drill

Description

Precision was founded in 1952 in Crystal Lake, IL. It is suitable for drilling holes to a depth up to six times the diameter of the drill size. For drill bit sizes 1.00mm/0.0394 inch and less than 18.00mm/0.71 inches, the drills are uncoated, without any additional treatment. It comes with a uncoated (bright) finish helps keep costs down, yet provides acceptable performance in most situations. For drill bit sizes between 19.00mm/0.7480 inches and 31.00mm/1.2205 inches, the drills have a black oxide finish. Drilling, or hole making, is the most common metalworking operation in the world. These drill bits have a right hand twist that brings the chips up and away from the cutting edge. The flutes of the drill bit act a passageway for chip extraction from the hole and for coolant to enter the hole. Together, the Precision Twist and Dormer brands represent a strong tool brand for high productivity carbide and high speed steel drill and tap products. The shank diameter is the same as the drill size. The bright finish facilitates chip flow in soft materials. They are made to DIN 340 industry standards, which ensure that drill bits around the world, confirm to the same specifications. This finish gives a strongly adhering surface treatment that acts to retain cutting fluid and prevent chip to tool welding, reducing the formation of a built-up edge. Twist drill bits are the most common type of drill bit used.
