Bordo 2011-M6 HSS Cobalt Jobber Drill Set

About Metric Cobalt Tough HSS-Co5 Jobber Drill 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 the need for end thrust.
• The 135º 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 jobber drills are extremely hard and provide superior performance and increased tool life especially in stainless steel and high tensile steel.

About Drill Bit Surface Treatment

• Bronze Finish (gold oxide).
• The metallic brown coloured low temperature temper treatment is normally only used on cobalt tools for identification purposes.
