13-piece M35 cobalt drill bit set

This new 13-piece set uses M35 high-speed steel with 5% cobalt for higher heat resistance and red hardness than standard HSS bits. It covers fractional sizes from 1/16 inch to 1/4 inch in 1/64-inch steps and comes in a metal storage case with clear scale markings for quick identification.

135-degree split-point tip for self-centering

The 135-degree split-point geometry prevents walk-off and enables faster, more precise starts on hard materials. Dual chip evacuation grooves clear debris efficiently during high-speed drilling in stainless steel, cast iron, titanium alloys and hardened plastics.

Capacity from 1/16 to 1/4 inch with uniform hardness

The M35 cobalt alloy maintains uniform hardness throughout each bit so edges can be resharpened repeatedly without loss of cutting performance. The range handles stainless steel, copper, aluminum, wood and plastics, but is not suited for diameters larger than 1/4 inch or for non-vertical drilling that risks bit breakage.

Questions about this item

How does the M35 cobalt blend perform when drilling stainless steel on a job site?

The 5 percent cobalt content raises heat resistance and red hardness so the bits keep their edge longer in tough alloys such as stainless steel and cast iron.

What shank style do these bits use and will they fit a standard drill chuck?

Each bit has a round straight shank that seats securely in any three-jaw chuck on handheld, bench or impact drills.

What are the smallest and largest diameters in the 13-piece set?

The range runs from 1/16 inch up to 1/4 inch with 11 intermediate sizes for fine increments.
