MILWAUKEE Red Helix™ Cobalt Drill Bit Kit 25PC
MILWAUKEE Cobalt RED HELIX Drill Bits are engineered for extreme durability and long life in hard metal applications. Designed with a variable helix that includes an aggressive 35° helix angle which ends at 15°, the Cobalt bits with RED HELIX provide rapid chip removal limiting heat buildup to stay sharper longer. The 135° split point tip delivers a precision start and prevents walking for fast, accurate holes. Ideal for tough applications and provide Up to 10X life vs. black oxide drill bits but can be used in all twist drilling applications.

- 118° Split Point (crankshaft point).
- Split point is self centering and reduces the need for end thrust. Friction at workpiece is reduced.
- 118° point angles are ideal for use in materials such as mild steel and cast iron.
- The 118° point creates easily controlled chips which are wide and thin.
- Bright Finish Twist Drills have no surface treatment and are supplied in the as-ground condition.
- These tools are suitable for general purpose use, particularly for non-ferrous applications.

BORDO LEFT HAND Cobalt HSS-Co5 Set
- HSS-Co5 (Cobalt) Left Hand Twist Drill Set
- Bordo Fractional Left Hand Cobalt Tough HSS-Co5 Twist Drills.
- 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 the need for 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.
- Cobalt HSS Twist drills are extremely hard and provide superior performance and increased tool life especially in stainless steel and high tensile steel.
- Left Hand Twist drills are ideal for use with screw extractors to remove broken bolts and screws.
- Bronze Finish (gold oxide) surface treatment. The metallic brown coloured low temperature temper treatment is normally only used on cobalt tools for identification purposes.

Black Finish HSS
BORDO Black Finish HSS Jobber Drill Fractional Set
- Bordo Black Knight M2-HSS Twist Drills.
- ANSI B94-11
- 118° Split Point (crankshaft point)
- Split point is self centering and reduces the need for end thrust.
- Friction at workpiece is reduced.
- 118° point angles are ideal for use in materials such as mild steel and cast iron.
- The 118° point creates easily controlled chips which are wide and thin.
- Black Finish Twist Drills (also called blue finish) achieve their distinctive colour by steam tempering, a thermal process resulting in a porous tool coating.
- This surface helps to keep lubricant on the tool, particularly important on the cutting edges, thus reducing friction and cold welding. The result is increased tool life.
- Black finish tools are generally recommended for ferrous applications where the oxide layer aids chip flow and heat dissipation.
