Saber 1/2" TiN Coated M2-HSS Twist Drill
ANSI B94-11
135° Split Point (crankshaft point).
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.
Gold Finish TiN Coating (Titanium Nitride) helps to dissipate heat and reduces friction and cold welding.
The coating higher speed and feed rates can be achieved and tool life is greatly increased.
The TiN coating is achieved by Physical Vapour Deposition (PVD).
As with all surface coated tools, performance will deteriorate after resharpening.
