13-Piece Cobalt Drill Bit Set M35

This 13-piece set contains M35 cobalt steel jobber-length bits ranging from 1/16 to 1/4 inch. The 5% cobalt alloy improves wear resistance and durability over standard high-speed steel. It suits professionals and DIY users drilling hardened metal, cast iron, stainless steel, plastics, and wood.

Check Chuck Capacity and Shank Type

Verify your drill chuck accepts round straight shanks up to 1/4 inch diameter. The jobber-length design requires sufficient spindle clearance for the full bit length. Ensure your tool delivers appropriate speed and torque control for cobalt steel to manage heat buildup during metal drilling.

Metal Storage Case and Split-Point Geometry

Bits are organised in a metal case that protects cutting edges during transport and storage. The 135-degree split point is self-centering, reducing bit walking and eliminating the need for a center punch. This geometry allows faster penetration with less pressure on hard materials.

Questions about this item

What sizes are in the 13-piece cobalt drill bit set and does it include a storage case?

The set contains 13 jobber-length bits from 1/16 inch through 1/4 inch in 1/64-inch steps and comes in a metal storage case for organisation.

Which material grade should I choose for drilling stainless steel and cast iron?

The M35 grade with 5 percent cobalt is hardened for stainless steel, cast iron and other tough alloys while still cutting softer metals, plastics and wood.

How does the 135-degree split point affect drilling in hard metal?

The 135-degree split point self-centres on contact, reduces walking and lets the bit penetrate hardened metal with less pressure and no centre punch.
