In a nutshell

The right choise for

With the Facom 229A.ST3 step drill bit, you drill and enlarge clean holes from 6 mm up to 38 mm in sheet metal, enclosures, and thin profiles without swapping bits. Thanks to the self-centering split point with cross grinding, the bit bites directly into the material, eliminating the need for center punching or pilot drilling. The twelve steps deburr hole edges as you advance, preventing snagging and deformation of your workpiece. a 10 mm cylindrical shank with 3 flats secures a non-slip grip in your drill chuck, while laser markings inside the flute make it easy to monitor your diameter progression.
