Saber X-SET HSS Metric Twist Drill Set with BONUS Countersink

About this item:

• 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).
