Professional Cobalt Drill Set

The Olympia Tools 13-piece M35 cobalt drill bit set covers sizes from 1/16 inch to 1/4 inch for drilling hardened metal, stainless steel, cast iron, wood and plastic. M35 cobalt steel reaches 67 Rockwell hardness for extended life compared with standard high-speed steel.

Sustained drilling performance

The 135-degree split point and gold oxide surface reduce walking and accelerate chip removal during continuous use. Two-flute geometry lowers friction and heat buildup so bits stay sharp longer when working through tough alloys.

Quick-change hex shank

Each bit has a 1/4 inch hex shank that locks securely into quick-change chucks without slipping. The included indexed holder keeps all 13 sizes organised, though the set is not intended for glass, ceramic or masonry work.

Questions about this item

Does the 1/4 inch hex shank slip in a locking quick-change chuck after hours of drilling hardened metal?

The 1/4 inch hex shank is designed for locking quick-change chucks and resists slipping or falling off during extended use.

What power tool chuck is required to use the 1/4 inch hex shank bits in the 13-piece set?

A 1/4 inch hex chuck or a locking quick-change chuck accepts the hex shank directly; no adapter is needed.

Will the M35 cobalt bits with 135° split points drill cleanly in the stainless steel I already work with?

The M35 cobalt bits reach 67 Rockwell hardness and the 135° split point prevents walking on stainless steel, cast iron and other hardened metals.
