Step Point Drill Bits

A cobalt step point set covering a fractional range, such as 1/8" to 1/2", offers the best balance of durability and versatility for most metalworking shops. M35 Cobalt construction resists heat buildup during extended use, making it well-suited for repeated drilling in steel, stainless, and other tough materials.

Our step point drill bits are made from M35 Cobalt, an alloy known for its heat resistance and hardness. This material composition allows the bits to maintain a sharp cutting edge longer than standard high-speed steel, especially when drilling through dense or abrasive metals.

Our fractional cobalt step point drill bits range from 1/8" to 1/2", with each bit capable of producing several distinct hole diameters along its stepped profile. This range covers most common metalworking and fabrication hole-sizing needs in a single tool.

Yes, M35 Cobalt step point drill bits are well suited for stainless steel and other hard metals due to their heat and wear resistance. Proper cutting speed and lubrication are still recommended to extend bit life and achieve clean hole edges.

Unlike standard twist bits that produce a single hole diameter, step point bits have a conical, staged design that lets one bit drill several hole sizes progressively. This reduces the number of tools needed and speeds up multi-diameter drilling jobs.
