13-Piece M35 Cobalt Drill Bit Set

This 13-piece set contains M35 cobalt steel drill bits ranging from 1/16 inch to 1/4 inch. The bits feature a 135-degree split point for self-centering and faster chip removal. They are designed for drilling hard materials such as stainless steel and cast iron. A plastic index case is included for storage.

For Metalworking and General Drilling

Suitable for users who need to drill stainless steel, cast iron, hardened steel, aluminum, wood, and plastic. The cobalt composition increases wear resistance for these applications. Not intended for buyers who require carbide-tipped bits for masonry, concrete, or tile. Also not for those needing sizes larger than 1/4 inch or specialized coating types.

135-Degree Split Point Geometry

The 135-degree split point allows the bit to start on contact without walking across the workpiece. This geometry also improves chip ejection during drilling. It is the key specification determining suitability for precision work in hard metals. The set includes 13 fractional sizes covering common pilot and clearance holes.

Questions about this item

Should I choose the 13-piece set or the 2-pack option?

The 13-piece set covers drill sizes from 1/16 to 1/4 inch in 13 increments, while the 2-pack simply provides two identical 13-piece sets for backup or high-volume use.

What does the 135-degree split point do when I am drilling stainless steel?

The 135-degree split point self-centres the bit, prevents walk-off on hard surfaces, and speeds chip removal so you cut stainless steel faster with less pressure.

Will the straight shank fit my 1/4-inch drill chuck?

Yes, each bit has a straight shank sized to its cutting diameter, so the largest 1/4-inch bit seats directly in a 1/4-inch chuck while smaller bits fit smaller chucks.
