Step Drill Bits

The unique cone shape of step drill bits helps create clean, burr-free holes, making them ideal for drilling sheet metal and plastic. These drill bits feature small ridges or steps from the narrow tip to the wide base.

What Is the Benefit of a Step Drill Bit?

The stepped design of these drill bits improves their functionality. You can use a single step drill bit to create different-sized holes by adjusting and controlling the drill depth. The tip can bore a small hole using shallow drilling, while drilling down to the base of the bit creates a larger hole. They can also make existing holes bigger. Step drill bits are often coated in titanium to reduce friction and increase durability. Attach the specialist bit to power drills to bore holes in steel, non-ferrous metals and hard plastics. At Toolstation, we stock the best step drill bits, cone drill bits and titanium coated step drill bits from trusted brands.

 

What is a step drill bit (cone drill bit)?

A step drill bit (or cone drill bit) is a conical bit with multiple graduated cutting diameters (“steps”) so you can drill different hole sizes with one tool.

When should I use a step drill bit instead of a regular drill bit?

Use a step drill on thin materials like sheet metal, plastic, laminates, or for enlarging holes. It avoids the need to keep swapping bits for different diameters.
