Bosch 2608597588 Double Ended HSS Ground Drill Bit - 4.00mm (10pack)

Drilling with Double Lifetime - The HSS Double-Ended Drill Bit Ground delivers double the drilling lifetime. The bit is usable at both ends due to two drill bit tips and flutes. It is ideally suited for assembly work, car body work and metal machining. It can also be used for drilling rivets or thread holes in thin-walled materials. Use this bit when drilling non-ferrous metal, sheet steel and plastics. It is intended for handheld drills (drill drivers) and drill stands. Additionally, the bit is extra short and stable for drilling in confined spaces. Active cutting and perfect centring without wandering are achieved by the pointed split-point tip, making pre-punching unnecessary.
