Precision Twist Drill 026215, 21.50mm Diameter 248mm OAL 118 Degree High Speed Steel Steam Oxide Taper Shank Drill Bit

Description

A drift pin is knocked into the slot at the tang to remove the tool. They are made to DIN 1897 industry standards (metric sizing), which helps ensure that drill bits around the world, conform to the same specifications. The 5ATS series has a type N flute form (a regular helix angle of 21 to 34 degrees) and has best performance when drilling into magnetic soft steel or structural steel (case carburizing steel). The taper of the tool fits into the taper of the tool-holder. Right-hand twist brings chips up and away from the cutting edge. The Precision Twist 5ATS jobber-length, black oxide-coated, general-purpose, Morse taper shank drill bit drills holes into a wide variety of metals and synthetic materials with performance in steel and cast iron. The friction between the surfaces provides a secure holding system and accurate placement of the tool. Precision manufactures machine tools under the following brands: Precision Twist, Precision Dormer, and Union Butterfield. These drill bits have a right-hand twist that brings chips up and away from the cutting edge. It can drill to a depth up to four times the diameter of the drill size. The flutes of the drill bit act a passageway for chip extraction from the hole and for coolant to enter the hole. They have locations around the world, and provide tools adhering to ANSI, NAS, and DIN standards. Drilling, or hole making, is the most common metalworking operation in the world. HSS assures good performance at an economical cost.
