Description
Set of 19 cobalt drills for metal with titanium nitride coating with cylindrical shank. A 5% cobalt content makes the drill bits more resistant to thermal damage during drilling. The ground helix ensures a low coefficient of friction and the drill bit is efficiently ejected outside the bore hole. This reduces the risk of chips sticking to the drill bit and increases the drilling capacity. 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 provides 40-60% faster drilling 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.
