About this item:
- Saber 3.90mm TiN Coated M2-HSS Twist Drill
- DIN338
- 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.
