HSS-Co5 (Cobalt) Left Hand Jobber Drill Set – Bordo

• 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.
