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

Description

Twist drill bits can be used in hand operated drills, standalone drill presses or a machine tool called a lathe, to drill a hole. The flutes of the drill bit act a passageway for chip extraction from the hole and for coolant to enter the hole. Twist drill bits are the most common type of drill bit used. 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. The 118-degree conventional point design is the most commonly accepted standard for drilling holes in a variety of material, such as wood, metal and synthetics. For drill bit sizes between 19.00mm/0.7480 inches and 31.00mm/1.2205 inches, the drills have a black oxide finish. It comes with a uncoated (bright) finish helps keep costs down, yet provides acceptable performance in most situations. 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. The bright finish facilitates chip flow in soft materials. Dormer Tools founded in 1913 in Sheffield, England, is known for innovative metalworking products. They are made to DIN 340 industry standards, which ensure that drill bits around the world, confirm to the same specifications. It is suitable for drilling holes to a depth up to six times the diameter of the drill size.
