Clean and accurate drilling
- Fast start without pilot: The Facom stepped drill bit allows you to drill directly without a pilot hole thanks to its self-centering split point design.
- Secure grip without slipping: A 3-flat cylindrical shank prevents micro-jamming and slipping in your drill chuck, ensuring smooth power transfer while working.
- Laser etched size markings: You can easily verify your drilling depth from 4 to 12 MM with clear, wear-resistant diameter markings inside the flute.
With the Facom 229A.ST0 step drill bit, you can create clean, accurate holes in thin sheet steel, aluminium, and plastic without constantly swapping bits. The self-centering split point lets you start drilling immediately without needing a pilot hole or wandering off mark. It steps smoothly through diameters from 4 to 12 MM, with laser-etched markings inside the flute for clear size identification. The 6 MM cylindrical shank with 3 flats prevents slipping and micro-jamming in your drill chuck. This ensures full control and efficient power transfer when creating cable entries or enlarging existing holes.
