13-Piece M35 Cobalt Drill Bit Set

This set contains 13 M35 high-speed steel twist bits with 5% cobalt for heat and wear resistance. Sizes range from 1/16 to 1/4 inch in 1/64-inch increments. A 135-degree split point centres the bit quickly with less pressure. A metal index case keeps bits organised.

Suited to metalworkers drilling stainless steel

The cobalt blend handles stainless steel, cast iron, copper and aluminium alloy effectively. It also cuts plastics and wood. The bits are not suitable for ceramic, glass or stone. Non-vertical drilling may cause breakage, so rigid setups are required.

135-degree split point for self-centring starts

This geometry reduces walking on hard surfaces and lowers the feed force needed. It is the key feature that determines whether the set matches your drilling accuracy needs.

Questions about this item

How can I verify the 135° split point is centering correctly on stainless steel?

The 135° split point should self-center and penetrate quickly with less pressure; if the bit walks or requires heavy force on stainless steel, the point may be dull or damaged.

What comes in the box and what must I supply separately?

The set includes 13 cobalt bits from 1/16 to 1/4 inch and one 3/8 drill chuck key in a indexed case; you must provide the drill or drill press.

Which version of this 13-piece M35 cobalt set should I choose for general metal and wood drilling?

This single 13-piece M35 cobalt set covers 1/16 through 1/4 inch and is rated for stainless steel, cast iron, copper, aluminum, plastics and wood; choose it for that range.
