M35 Cobalt Drill Bit Set 13pcs

The Olympia Tools M35 Cobalt Drill Bit Set contains 13 pieces ranging from 1.5 to 6.5mm. It is made from 5% Cobalt M35 HSS-CO material for high hardness and heat resistance. The straight shank design suits mechanical or hand drills. A storage case keeps the bits organised and portable.

For metalworkers drilling stainless steel and alloys

This set suits professionals and hobbyists who need durable bits for stainless steel, cast iron, copper and aluminum. The cobalt alloy withstands high temperatures during extended drilling sessions. Buyers who primarily drill wood, plastic or masonry should look at something else because the geometry and material are optimised for hard metals only.

13-piece metric range 1.5-6.5mm

The set provides 13 individual drill bits covering diameters from 1.5mm to 6.5mm. This range determines whether the kit matches the hole sizes required for a specific project. Users needing diameters outside this spread or a larger quantity of bits will need a different set.

Questions about this item

Will the 5 % cobalt M35 bits run hot when drilling stainless steel all day?

The M35 HSS-CO material is described as having outstanding heat resistance, so the bits maintain performance during extended high-temperature drilling in stainless steel and other hard metals.

What chuck size do I need on my drill to hold the 6.5 mm shank?

The set uses an industrial straight shank design; your drill chuck must accept at least a 6.5 mm diameter shank for the largest bit.

Can the 1.5 mm cobalt bit be used in an older hand drill with a 1.5 mm capacity chuck?

Yes, the smallest bit is 1.5 mm and the straight shank fits any drill chuck that can grip that diameter, allowing use with older hand drills.
