Sizes: Available (see availability), e.g. 4-12, 6-20, 4-32, 4-39 mm or also available in a set of 3 (4-32 mm) or 4 pack (4-39 mm).
Automatic centring: thanks to the special shape of the tip, the step drill can be centred even on rounded and slippery surfaces. So you don't need to use a grain.
Sharp edges? No. The special shape significantly and automatically reduces the formation of burrs.
VERSATILE - Ideal for materials such as steel, non-ferrous metal, sheet metal, wood, plastics, etc. | |
