135° Split Point (crankshaft point)
Drill Bit Surface Treatment
Gold Finish (TiN) (Titanium Nitride)
A very hard gold coloured surface finish a few microns thick is achieved by Physical Vapour Deposition (PVD). As with all surface coated tools, performance will deteriorate after resharpening. The coating helps to dissipate heat and reduces friction and cold welding. Higher speed and feed rates can be achieved and tool life is greatly increased. Split point is self centering and the short distance from the drill axis to the outer corners results in faster penetration, reducing end thrust. The 135° point should be used to cut harder steel materials especially in deep hole applications. In these situations it will produce thicker chips minimising work hardening of the cavity. Faster penetration reduces abrasion and friction along the cutting edges.
