13-piece M35 cobalt drill bit set

This 13-piece set covers diameters from 1/16" to 1/4" in 64th-inch increments. The M35 high-speed steel construction targets hardened metal, stainless steel, cast iron, wood and plastic. A moulded index case keeps each bit labelled and organised for workshop or job-site use.

Check shank fit and material hardness

Verify that your drill chuck accepts straight shanks up to 1/4" diameter. Confirm the workpiece hardness matches M35 capabilities; the set is intended for materials up to hardened steel and stainless. No hex or reduced shanks are included, so impact drivers with quick-change collets may not hold these bits securely.

Heat resistance and cutting behaviour

M35 cobalt alloy retains hardness at elevated temperatures generated when drilling steel. The 135-degree split point reduces thrust and walk-off, lowering friction and heat buildup. In normal use the bits run cooler than standard HSS, extending edge life without requiring cutting fluid for most thin-section work.

Questions about this item

What does the 13-piece M35 cobalt drill bit set include and is a storage case provided?

The set contains 13 jobber-length bits from 1/16" to 1/4" in 1/64" steps plus an index storage case for organisation.

How do I choose between the 13-piece 1/16"-1/4" set and the larger 29-piece or 115-piece versions?

The 13-piece set covers the most common small diameters; the 29-piece extends to 1/2" and the 115-piece adds more intermediate sizes for wider ranges.

What does the 135° split point mean when I am drilling stainless steel or cast iron?

The 135° split point self-centres on hard materials, reduces walk-off and clears chips faster for cleaner holes in stainless steel and cast iron.
