The Irwin Metric TCT (Tungsten Carbide Tipped) Drill Bits offer precision drilling with stationary machines in hardened steel cast iron bronze alloys and manganese alloyed steel. The C2 Carbide Tip more→will drill hardened material up to a hardness of 50 Rockwell C and is four facetted ground for low drilling pressure and perfect centring. The body of the drill bit is made from Chrome Vanadium Steel hardened to 56 Rockwell C. A coolant should always be used when drilling with TCT twist drill bits. Irwin suggest the use of a 3- 6% emulsion. The coolant will extend the lifetime of the drill bit.Irwin HSS TCT tip drill bit. Specifications:Diameter: 11.5mm.Total length: 142mm.Working Length: 94mm.…

Fully ground HSS Cobalt drill bit manufactured to DIN 338. 5% Cobalt gives increased heat hardness which helps extend the life of the drill bit. 135° Split point is self-centring which helps to reduce more→thrust and aids an easier penetration.
