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

Description

They are made to DIN 1897 industry standards (metric sizing), which helps ensure that drill bits around the world, conform to the same specifications. 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. The 5ATS series has a type N flute form (a regular helix angle of 21 to 34 degrees) and has performance when drilling into magnetic soft steel or structural steel (case carburizing steel). 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. HSS assures good performance at an economical cost. A drift pin is knocked into the slot at the tang to remove the tool. Spiral flutes act as a passageway for chip extraction from the hole and for coolant to enter the hole. Twist drill bits are commonly used to drill holes with hand-operated drills, standalone drill presses, or lathes. Twist drill bits are the most common type of drill bit used. 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. The friction between the surfaces provides a secure holding system and accurate placement of the tool. They have locations around the world, and provide tools adhering to ANSI, NAS, and DIN standards.
