Bosch Professional HSS-R Stub Drill Bit DIN1897 - 4.0mm x 22mm x 55mm

The HSS Stub Drill Bit is an extra-short drill bit for drilling in confined spaces, producing holes in sheet metals and pipes with a thickness of 2-6 mm. It offers a flute with an ideal working length for most types of tight work. An easy start without pre-punching is provided by the self-centring split-point tip, which prevents walking and enables effective drilling in areas with limited clearance. It is suitable for use on structural steel, alloyed metal, non-ferrous metal and plastics. This drill bit has a cylindrical shank system (shank equal to drill bit diameter) and is intended for use in drill stands and drill drivers. The HSS Stub Drill Bit is manufactured to DIN 1897. The drill bit is Type N (flute angle) with a 118-degree tip and a diameter tolerance of h8. Moreover, it is especially suitable for handheld drills.
