HIGH QUALITY MATERIAL: 5% Cobalt High Speed Steel M35 provide extended tool life compared to ordinary drill bits. Durable and strong

TWIST DESIGN & PERFORMANCE: PRECISE 135°SPLIT POINT, gold oxide finish and round straight shanks. Prevent walking, clear chips and particles faster.Produced by precision fully ground which ensures chips move smoothly.

PROFESSIONAL & WIDELY USE: M35 Cobalt HSS is more suitable for hardened material. Particularly successful in cutting through hard metals such as stainless steel, cast iron, high temperature alloy, titanium alloy, hard plastics and woods, and also can be used for softer materials.
