13-piece M35 cobalt drill bit set

This 13-piece set uses M35 high-speed steel with 5% cobalt for drilling hardened metal, stainless steel, cast iron, titanium alloy, hard plastics and wood. The range covers 1/16 inch through 1/4 inch in jobber lengths. It suits trade and workshop users who need heat-resistant bits for tough materials.

Rose plastic case with size index

The included holder organises every bit in a labelled layout so the correct diameter is found quickly. The case protects the cutting edges during transport and keeps the set complete on a busy bench. No separate storage is required.

M35 cobalt extends life in hard alloys

The 135-degree split point self-centres and reduces walking on stainless steel, cast iron and high-temperature alloys. Fully ground spiral flutes clear chips faster to lower friction and heat. The set stops at 1/4 inch, so larger diameters need a different kit.

Questions about this item

Will the M35 cobalt bits need resharpening after drilling stainless steel?

The 5 % cobalt M35 steel and 135 ° split point resist wear, so resharpening is needed far less often than with standard HSS bits.

What stops the 1/16″ bit from snapping during deep holes?

The jobber length and fully ground spiral flutes clear chips fast, reducing torque buildup that breaks small diameters.

Does the gold-oxide finish stay cool when the set runs all day in cast iron?

The finish lowers friction and the cobalt alloy handles heat, keeping temperatures lower during extended drilling sessions.
