13-piece M35 cobalt drill bit set

The Pro Edge Technology M35 set contains 13 jobber drill bits ranging from 1/16" to 1/4" in 1/64" increments. Made from M35 steel with 5% cobalt, they offer 3-5x longer life than standard M2 HSS bits. The bronze finish resists wear during high-speed drilling. A sturdy case keeps the bits organised and protected.

Metalworkers and DIY users needing cobalt hardness

Ideal for tradespeople and hobbyists who regularly drill stainless steel, cast iron, copper, aluminium and plastics. The 135° split point reduces walking and lowers feed pressure on hard materials. Not suited for buyers who need larger diameters beyond 1/4", extra-long series bits or bits for masonry and concrete.

M35 cobalt alloy with 135° split point

The defining specification is the M35 high-speed steel containing 5% cobalt combined with a 135° split-point geometry. This pairing delivers the heat resistance and self-centring accuracy required for repetitive drilling in tough alloys. If your work demands that specific material grade and point angle, this set matches the requirement.

Questions about this item

Will the 1/16" to 1/4" cobalt bits fit my older 3/8" chuck drill?

Yes, every bit in the 13-piece set has a shank no larger than 1/4", so all 13 fit a standard 3/8" chuck without an adapter.

How do I confirm the 135° split point is cutting correctly on stainless steel?

The bit should self-centre without a pilot hole, produce short curled chips and show no blue discolouration on the cutting edges after a full-depth hole.

Does the set include a case or do I need to buy storage separately?

A sturdy storage case with labelled slots for all 13 bits is included; pull the top tab to open it without damaging the latch.
