What It Is

This stepped point cobalt drill bit is a premium industrial cutting tool engineered for stainless steel and hardened metals. Featuring precision stepped point geometry and a 135° split angle, it is designed to start cleanly, minimize heat buildup, and extend tool life in demanding metal drilling applications. The 1/4" quick change hex shank allows fast bit swaps and secure use in impact drivers and drill/drivers.

What Makes It Different

Unlike standard drill bits, the stepped point geometry begins cutting immediately on contact. The design helps the bit self-center, significantly reducing walking and eliminating the need for a pilot hole in most applications. The 135° tip angle is optimized for stainless steel and other high-strength alloys, allowing smoother entry and improved stability throughout the cut.

Manufactured from premium cobalt alloy, this drill bit offers superior wear resistance and heat tolerance compared to standard high-speed steel (HSS) bits. The cobalt composition maintains edge sharpness longer, especially when drilling tough, abrasive materials.

The 1/4" quick change hex shank provides secure engagement in impact drivers and quick-change chucks, reducing slippage and allowing rapid bit changes on the jobsite. This makes it especially effective for installation, fabrication, and field work where speed and efficiency matter.

Applications

Ideal for use in drill presses, CNC machines, and heavy-duty hand drills, this stepped point cobalt drill bit is built for precision metalworking environments including industrial fabrication, automotive repair, aerospace manufacturing, and general machining. Designed for:

• Stainless steel
• Hardened steel
• Alloy steel
• Tool steel
• Cast iron
• Aluminum and brass
• Acrylics

Frequently Asked Questions

What makes a stepped point drill bit better than a standard drill bit?

A stepped point begins cutting immediately and stays centered as it enters the material. This reduces walking, improves hole accuracy, and produces cleaner holes compared to standard 118° or split point drill bits.

Do stepped point drill bits require a pilot hole?

No. Stepped point drill bits are designed to self-center on contact, which reduces walking and eliminates the need for a pilot hole in most stainless steel and hardened metal applications.

What is a stepped point drill bit used for?

A stepped point drill bit is used for drilling stainless steel, hardened steel, and other tough metals where accuracy, reduced walking, and clean hole quality are important.

Is cobalt better than HSS for stainless steel?

Yes. Cobalt drill bits offer higher heat resistance and improved wear characteristics compared to standard high-speed steel (HSS), making them better suited for stainless steel and hard alloys.

What materials can a stepped point cobalt drill bit cut?

Stepped point cobalt drill bits are designed for stainless steel, hardened steel, alloy steel, tool steel, cast iron, aluminum, brass, and acrylic.

Can stepped point drill bits enlarge existing holes?

Yes. The stepped geometry allows the bit to enlarge existing holes or create new, smoother holes with improved stability and reduced chatter.

What does a 135° tip angle do?

A 135° tip angle improves centering and stability when drilling hard metals. It reduces walking and allows the bit to engage stainless steel more efficiently than a standard 118° tip.
