12-Piece Cobalt Drill Bit Set
This Olympia Tools set contains twelve 13/64 inch cobalt drill bits made from M35 high-speed steel with five percent cobalt for wear resistance. Each bit measures 5.16 mm in diameter with a 63 mm flute length and 94 mm overall length. The 135-degree split point prevents walking and eliminates the need for a centre punch. A storage case keeps bits organised and identifiable.
Suited For Metalworkers And General Drilling
The bits handle stainless steel, cast iron, copper, aluminium, brass, plastic and wood, making them useful for workshop tasks that involve mixed materials. Builders who need a wide range of diameters in one package should look at a multi-size index instead. Users requiring carbide-tipped or coated bits for abrasive composites will need a different product.
135-Degree Split Point Geometry
The 135-degree split point with straight shank self-centres on contact and reduces thrust, giving faster, cooler drilling in hard metal up to 1100 degrees Fahrenheit. Dual flutes clear chips efficiently for sustained cutting speed. This geometry is the single feature that determines whether the set matches your precision and heat-control requirements.

Questions about this item
How do I install the 13/64 inch cobalt bit in my drill chuck and what step do people often miss?
Open the chuck wide, insert the straight shank fully, and tighten securely; the step many skip is verifying the 135° split point sits true before drilling so the bit self-centres without a centre punch.
What maintenance or replacement will the M35 cobalt bits need after repeated use?
The M35 high-speed steel with 5% cobalt resists wear up to 1100°F; when cutting edges dull, replace the bit — there is no sharpening service or coating to renew.
What limit appears first when drilling stainless steel continuously with these 63 mm flute-length bits?
Heat builds in the 63 mm flute length during sustained cuts; the 1100°F maximum working temperature is reached before the cobalt alloy loses hardness, so pause to cool the bit.
