Description

Precision was founded in 1952 in Crystal Lake, IL. 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. For drill bit sizes between 19.00mm/0.7480 inches and 31.00mm/1.2205 inches, the drills have a black oxide finish. Together, the Precision Twist and Dormer brands represent a strong tool brand for high productivity carbide and high speed steel drill and tap products. 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. 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. These drill bits have a right hand twist that brings the chips up and away from the cutting edge. 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 machine tool called a lathe, to drill a hole. For drill bit sizes between 19.00mm/0.7480 inches and 31.00mm/1.2205 inches, the drills have a black oxide finish. The flutes of the drill bit act a passageway for chip extraction from the hole and for coolant to enter the hole. Dormer Tools founded in 1913 in Sheffield, England, is known for innovative metalworking products. It is suitable for drilling holes to a depth up to six times the diameter of the drill size.
