25-Pc HSS-G TiN Coated Drill Bit Set

Flute Type: Standard helix, right hand, ground flutes
Point Angle: 135° split point
Surface Treatment: TiN coated
Application: Drills in steel, high tensile steel up to 900N/mm2, cast steel, cast iron, metals and hard plastics. 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.
