With the Facom 678014 stepped pg drill bit, you produce accurate cylindrical holes in sheet metal up to 4 mm thick without needing a pilot hole. Covering stepped diameters from 6 to 37 mm, it allows you to drill clean cutouts for standard PG7 to PG29 cable glands with ease. This eliminates the hassle of switching between multiple drill bits while preventing sheet deformation and burrs. The 10 mm cylindrical shank with 3 flats delivers a secure grip in your drill chuck, preventing slipping and micro-locking during electrical installation work.
