4mm HSS Cobalt Jobber Drill – Bordo

• 4mm HSS Cobalt Twist Drill – Clam
• Bordo Metric Cobalt Tough HSS-Co5 Twist Drills.
• 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 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.
• Bronze Finish (gold oxide) surface treatment. The metallic brown coloured low temperature temper treatment is normally only used on cobalt tools for identification purposes.
