Saber HSS Cobalt Co5 Jobber Drill Set ABS Plastic Case

• Saber HSS-Co5 (Cobalt) Jobber Drills DIN338.

135° Split Point (crankshaft point)

• The 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.

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.
