Saber Metric TiN Coated M2 - HSS Jobber Set

• Saber TiN Coated M2-HSS Jobber Drills DIN338.

135° Split Point (crankshaft point)

• The 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.

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.
