Diager HSS-Co G3 Multi-Layer Coated 5% Cobalt Metal Drill Bit

HIGHLIGHTS:

The Diager HSS-Co G3 Multi-Layer Coated 5% Cobalt Metal Drill Bit is a premium fully ground HSS drill bit engineered for high-speed, precision drilling in ferrous metals. Manufactured with 5% cobalt high-speed steel and protected by a multi-layer Titanium, Aluminium, and Nickel coating, it delivers exceptional wear resistance, reduced friction, and superior thermal protection for extended service life.

Its 135° split point ensures accurate hole positioning with minimal walking, while the Type S flute efficiently evacuates medium and long chips for smoother drilling. The advanced multi-layer coating acts as a thermal barrier, allowing faster cutting speeds while minimizing heat build-up during continuous drilling operations.

Designed for professional engineers, machinists, and industrial fabricators, the Diager HSS-Co G3 drill bit provides excellent drilling performance in alloy steels, non-alloy steels, and cast irons.
