Set of 6 pcs cobalt titanium nitride coated metal drill bits with cylindrical shank. The 5% cobalt content makes the drill bit more resistant to thermal damage during drilling. The ground helix ensures a low coefficient of friction and the excavated material is efficiently transported out of the hole. This reduces the risk of chips sticking to the drill bit and increases drilling efficiency. This design reduces vibration, which has a positive effect on the durability of the drill bit. The tip angle of 135° ensures perfect centring. The drill bit provides a 40-60% reduction in price compared to standard HSS drills. Suitable for: steel, cast iron, aluminium, copper, brass. Manufactured according to standard DIN338. All packed in a handy, convenient box.
