20-Piece 1/16" Cobalt Drill Bit Set

This 20-piece set supplies 1/16-inch cobalt drill bits made from M35 high-speed steel with 5% cobalt content. The bits target users who regularly drill hardened metal, stainless steel, cast iron, hard plastic and wood. A plastic storage case keeps the small-diameter bits organised and protected between jobs.

Upgrade From Standard HSS Bits

The M35 cobalt alloy is harder than conventional high-speed steel, so the bits retain sharp edges longer when cutting tough alloys. The 135-degree split-point tip centres itself without a centre punch and reduces walking on hard surfaces. The step up is worthwhile when standard bits dull quickly or wander on stainless steel and cast iron.

Capacity And Headroom For Small-Hole Work

Each bit measures 1.588 mm in diameter with tolerance held to within -0.03 mm, giving consistent hole size in repetitive tasks. The set covers high-volume needs for 1/16-inch pilot and clearance holes in metal, PVC board and wood. It does not address larger diameters, so buyers needing holes above 1/16 inch will require additional sizes.

Questions about this item

What size drill chuck is required for the 1.588 mm shank on these bits?

A standard 1/16 inch or 2 mm drill chuck will grip the 1.588 mm shank securely.

How do I start a hole without the 135-degree split point walking on hardened steel?

Apply steady pressure at low RPM; the 135-degree split point self-centres so no centre punch is needed.

When should I replace a bit from this 20-piece M35 cobalt set?

Replace a bit when the cutting lips are chipped or the 135-degree point can no longer self-centre within the -0.03 mm tolerance.
