Complete Size Set

This 13-piece cobalt drill bit set covers sizes from 1/16 inch to 1/4 inch in 1/64-inch increments. The indexed plastic case keeps every bit organised and easy to transport. It suits DIYers, woodworkers and metalworkers who need a ready-to-go range for everyday drilling tasks. Builders who need larger diameters or specialised step bits will need a different kit.

M35 Cobalt High Speed Steel

Each bit is made from M35 HSS containing 5% cobalt for superior wear and heat resistance. The material stays hard at high temperatures, so the cutting edges last longer than standard HSS when drilling stainless steel, cast iron or hardened steel. It also handles copper, aluminium, plastic and wood without trouble.

135° Split Point & Chip Evacuation

The 135-degree split point centres instantly on contact, preventing walk and ensuring accurate hole placement. Spiral flutes clear chips quickly, reducing friction and heat build-up during extended use. This geometry keeps the bit running cooler and quieter in hand drills or drill presses.

Questions about this item

What does the 135-degree split point do once the bit is in the drill?

The 135-degree split point centres the bit instantly on contact, stops it from wandering, and the spiral flutes clear chips quickly for a cleaner hole.

What does the M35 cobalt designation mean for the steel itself?

M35 high-speed steel contains 5 percent cobalt, giving the bits higher heat resistance and wear life than standard HSS when drilling hard metals.

What shank style do these bits use and will they fit my drill?

They have a straight round shank that fits any standard three-jaw chuck on corded or cordless drills.
