Cobalt Drill Bit Set for Hardened Metals

This Olympia Tools kit contains ten M35 cobalt high-speed steel drill bits sized at 11/64 inch. The 5% cobalt content increases hardness and wear resistance compared to standard HSS. A 135° split point prevents walking and eliminates the need for a centre punch. The set includes a connectable storage case with moulded size markings.

Suited for stainless steel.

These jobber-length bits handle hardened steel, stainless steel, cast iron, aluminium alloy, wood and plastic. They are not for buyers who need a range of diameters, longer bits for deep holes, or reduced-shank bits for small-chuck drills. Users who require carbide tips for abrasive composites or high-volume production should look elsewhere.

135° split point with straight shank

The fully ground spiral groove clears chips quickly to reduce friction and heat. The 135° split point starts on contact without a pilot mark, giving precise, faster drilling in hard materials. The straight shank fits standard drill chucks. Controlling speed, pressure and heat remains essential for bit life.
