Description
About this item:
- 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.
