HSS-TiN Metal Drill Bits, DIN 338 3,5 x 39 x 70 mm

The HSS Twist Drill Bit Titanium offers maximum lifetime while drilling holes in metal. When using the appropriate cooling system, the drill bit has the lowest possible level of friction and minimal wear, due to its titanium-nitride coating. The high surface quality of this ground twist drill bit, which is made from HSS (high-speed steel), allows for extended usage. It is suitable for use on alloyed and non-alloyed steel, malleable cast iron, sintered iron, new silver, copper, bronze and hard ...plastics such as perspex. The HSS Twist Drill Bit Titanium is manufactured to DIN 338. The drill bit is Type N (flute angle) with a 135-degree tip and a diameter tolerance of h8. Active cutting and perfect centring without wandering are achieved by the pointed split-point tip. Do not use with aluminium and only work with a cooling agent. 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._
