13-Piece Cobalt Drill Bit Set

This Olympia Tools set contains 13 metric drill bits ranging from 1.5 mm to 6.5 mm. The bits are made from M35 high-speed steel with 5% cobalt for increased hardness and heat resistance. They feature a 135-degree split point to reduce walking on hard surfaces. A plastic storage case with size markings is included.

For Metalworking And General Drilling

The bits suit users drilling stainless steel, cast iron, copper, aluminium, plastics and wood. They are not designed for glass, ceramics or masonry. The split point is not self-centering, so a centre punch is recommended on smooth or curved materials. Buyers needing imperial sizes or larger diameters should look elsewhere.

5% Cobalt M35 Steel Construction

The cobalt alloy improves wear resistance and tool life compared to standard high-speed steel when cutting hard metals. Precision-ground flutes help clear chips efficiently. The round straight shank fits standard three-jaw drill chucks.

Questions about this item

How can I confirm the 135° split-point tips are cutting cleanly in stainless steel after setup?

Drill a test hole in scrap stainless steel; the 5% cobalt M35 bits should produce a continuous chip without wandering, showing the 135° geometry is engaging properly.

What comes in the plastic storage box and is anything else required to start drilling?

The box holds 13 metric cobalt bits sized 1.5, 2, 2.5, 3, 3.2, 3.5, 4, 4.5, 4.8, 5, 5.5, 6 and 6.5 mm; only a compatible drill chuck and cutting fluid are needed separately.

Which diameter should I pick first for a 4.8 mm clearance hole in cast iron?

Select the 4.8 mm bit from the 13-piece set; its 5% cobalt construction handles cast iron heat and the 135° point reduces walk on the hard surface.
