Drill Bit Size Finder

Drill bits are chosen by material to be drilled, diameter and shank. Metal: HSS twist drills to DIN 338 (jobber length) and DIN 340 (long), HSS-G ground, HSS-Co (5 % cobalt) for stainless and hard steel, TiN-coated for longer life, in 0.5 mm steps from 1 to 13 mm with reduced shanks above 13 mm. Masonry and concrete: SDS-Plus (to about 30 mm) and SDS-Max (to 52 mm) hammer bits with carbide heads, in lengths from 110 to 1000 mm. Wood: auger, self-feed, spade and Forstner bits; tile and glass: diamond and spear-point bits; sheet metal: step drills and hole saws. The finder lists the catalogue by type and diameter so a bit of the right size and shank can be quoted.

For stainless steel use HSS-Co bits at low speed with cutting fluid; standard HSS overheats and work-hardens the material. Match the shank to the machine — SDS-Plus bits do not fit SDS-Max chucks (an adapter reduces impact energy). Installation drills (long SDS bits with a hole for pulling cable) are listed with their total length.

Coverage: 184 of 184 catalogue rows with a readable size are listed (257 rows in these categories in total; the remainder can be found through the site search by part number).
