Point Angle

Surface Treatment
TiN coated
Application
Drills in steel, high tensile steel up to 900N/mm2, cast steel, cast iron, non-ferrous metals and hard plastics.Tin coating will increase the tool life and performance. Compared to traditional HSS jobber drill bits, speed can be increased by 40 -60% and feed by 10 -20% without reducing the life time of the drill bit significantly. TiN is also a poor conductor of heat, so the heat generated during the drilling process is diverted into the chips and coolant and less into the drill bit.
