Diager HSS-Co G3 Multi-Layer Coated 5% Cobalt Metal Drill Bit Set ( 5 to 10 pieces )

HIGHLIGHTS:

The Diager HSS-Co G3 Multi-Layer Coated 5% Cobalt Metal Drill Bit Set contains premium fully ground HSS drill bits engineered for high-speed, precision drilling in alloy and non-alloy steels. Manufactured with 5% cobalt high-speed steel and protected by a TiAlN (Titanium Aluminium Nitride) multi-layer coating, these drill bits provide exceptional wear resistance, reduced friction, and outstanding heat protection for demanding industrial applications.

Each drill bit features a 135° split point for precise hole positioning with minimal wandering, while the Type S flute efficiently evacuates medium and long chips. The advanced TiAlN coating acts as a thermal barrier, reducing heat generation, increasing cutting speed, and extending tool life during continuous drilling.

Available in convenient packs of 5 to 10 pieces, the Diager HSS-Co G3 drill bit sets are ideal for fabrication shops, engineering workshops, industrial maintenance, and professional metalworking.
