10-piece M35 cobalt drill bit set

This 10-piece set supplies 1/16 inch M35 high-speed steel bits with 5 percent cobalt for cutting stainless steel, cast iron, copper, aluminium alloy, plastics and wood. The split-point geometry centres automatically and penetrates quickly with less pressure, reducing wandering on hard materials. It is aimed at metalworkers and general fabricators who need repeatable small-diameter holes in tough alloys.

Heat wear resistance and chip clearance

The M35 cobalt alloy resists heat buildup and wear during extended drilling in stainless steel and cast iron, helping maintain cutting edges longer than standard high-speed steel. The 135-degree split point lowers thrust force, which in turn reduces frictional heat at the tip. Twist flutes evacuate chips smoothly, preventing clogging that can raise temperatures further.

Portable case and usage limits

A compact indexed case organises all ten bits for quick selection and protects cutting edges during transport and bench storage. The bits are not rated for ceramic, glass or masonry, and non-vertical drilling may cause breakage, so they suit drill-press or guided handheld work best. Builders needing larger diameters or masonry capability will require different tooling.

Questions about this item

How do I install the 1/16 inch M35 cobalt bits in my drill chuck without breaking them?

Insert each bit straight into the chuck jaws, tighten securely, and start drilling perpendicular to the workpiece; non-vertical use can snap the 1/16 inch bits.

When will the 135° split points on these 10 M35 cobalt bits need replacement?

Replace individual bits when the 135° split points no longer self-centre or when cutting stainless steel, cast iron, or hardened steel becomes noticeably slower.

What is the first limitation I will hit when drilling stainless steel continuously with these 1/16 inch cobalt bits?

Heat buildup in the small 1/16 inch diameter will dull the 5% cobalt edges fastest under sustained high-speed drilling in stainless steel.
