Saber 8012-M6 HSS-Co5 (Cobalt) Jobber Drill Set - ABS Plastic, 25 Pieces

Saber 8012-M6 HSS-Co5 (Cobalt) Jobber Drill Set

• Saber HSS-Co5 (Cobalt) Jobber 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 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
