13-piece M35 cobalt drill bit set

This DeWalt set contains 13 M35 cobalt steel drill bits ranging from 1/16 inch to 1/4 inch. The 5 percent cobalt alloy gives each bit hardness that exceeds standard high-speed steel. Bits are organised in an indexed storage case for quick selection. It suits trade professionals and serious DIY users who drill hardened metal regularly.

135-degree split-point geometry under load

The 135-degree split-point tip centres itself on contact and reduces wandering when pressure is sustained. Precision-ground spiral flutes evacuate chips continuously so the cutting edges stay clear during deep holes. This geometry resists the heat build-up that causes ordinary bits to bind or snap in stainless steel, alloy steel and cast iron.

M35 cobalt steel composition

The defining specification is the M35 grade steel with 5 percent cobalt content. This metallurgy delivers the hardness required for hardened metal, stainless steel and cast iron while retaining enough toughness for softer materials such as copper, aluminium, plastic and wood. Buyers who need carbide-tipped bits for masonry or concrete should look elsewhere.

Questions about this item

How much heat builds up in the M35 cobalt steel bits during all-day drilling in stainless steel?

The 135° split-point geometry and precision spiral flutes eject chips quickly, reducing friction and heat buildup during extended use in hard materials.

What chuck type must my drill have to accept these hex-shank bits?

A hex chuck is required; the set's 13 pieces all feature hex shanks designed for that interface.

Will the 1/16″ to 1/4″ range cover the same holes I currently drill with older high-speed steel bits?

Yes, the 13 sizes from 1/16″ through 1/4″ match common fractional increments, so they replace equivalent HSS bits while adding M35 cobalt hardness.
