Saber X-SET HSS-Co5 (Cobalt) Twist Drill Set - 8012-XM3

• Saber 25 Piece HSS-Co5 (Cobalt) Twist Drill Set 1.0-13.0mm x 0.5mm rises.
• 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.

Note:

• BONUS 16mm TiN coated HSS-Co5 (Cobalt) triple flute countersink
