What are the standards for drill bits?
Drill bits are cutting tools used to remove material to create holes, almost always of a circular cross-section. Drill bits are available in different types and diameters depending on the type of material to be drilled and the size of the hole required.
The main standards for drill bits are outlined below:
DIN 333 standard: 60° center drill bits, R, A and B types
DIN 338 standard: shot cylindrical drill bits
DIN 340 standard: long cylindrical drill bits
DIN 345 standard: Morse taper drill bits
DIN 1869 standard: extra-long cylindrical drill bits
DIN 1870 standard: extra-long Morse taper drill bits
DIN 1897 standard: extra short cylindrical drill bits
DIN 6537 standard: solid twist drill bits in hard metals with cylindrical shank
DIN 6539 standard: solid drill bits in hard metals with cylindrical shank
DIN 8037 standard: cylindrical drill bits with carbide inserts for metallic materials
DIN 8374 standard: step drill bits with cylindrical shanks for through holes and chamfers for countersunk head screws
DIN 8378 standard: step drill bits with cylindrical shank for tapping pilot holes
DIN 8379 standard: step drill bits with Morse taper shank for tapping pilot holes
