13-piece cobalt drill bit set
The Olympia Tools set contains thirteen M35 high-speed steel twist bits with a 5-percent cobalt alloy. A bronze steam surface treatment adds hardness and toughness for wear resistance. The 135-degree split-point tip is self-centring and reduces thrust for faster penetration. Bits range from 1/16 inch to 1/4 inch and come in a metal storage case with a size index.
Suitable for hard metals and general use
Machinists and maintenance technicians drilling stainless steel, cast iron, titanium alloy or high-temperature alloys will benefit from the cobalt construction. The bits also handle plastics and wood. Users who need diameters larger than 1/4 inch or a greater quantity of bits for production runs should look at a larger set.
M35 cobalt alloy with 135-degree split point
The 5-percent cobalt M35 steel and 135-degree split-point geometry determine whether this set matches the application. This combination delivers the heat resistance and self-centring start required for hard-metal drilling.

Questions about this item
Does the 135-degree split point tip reduce heat build-up when drilling stainless steel all day?
The self-centring 135-degree split point tip lowers thrust and speeds chip removal, which helps control heat during extended drilling in hard metals such as stainless steel and cast iron.
Will the round shank on these M35 cobalt bits fit my standard 1/4-inch drill chuck without an adapter?
Yes, each bit has a round shank that seats directly in a standard three-jaw drill chuck, so no extra adapter is needed for the 1/16 to 1/4 inch sizes supplied.
Can I mix these jobber-length cobalt bits with my older high-speed steel sets in the same metal index case?
The set includes a metal storage box with a size index that holds all 13 jobber-length bits, and the case will also accommodate older bits of the same diameters.
