Manufactured from premium HSS with a Titanium Nitride coating, these step drills are engineered for reduced heat, improved wear resistance, and long service life. The self-starting tips prevent drill wandering, ensuring accuracy and control for clean, precise holes across multiple diameters.

What materials can these step drills cut?

This set is ideal for drilling thin materials such as sheet metal, stainless steel, copper, brass, aluminium, plastics, and laminates.

What size range does this set cover?

The set includes three step drills that collectively cover a wide range of hole sizes:

• 4–12mm

• 4–20mm

• 6–30mm

This comprehensive range makes the set ideal for a wide variety of drilling applications, from small pilot holes to larger openings.

What are the key features of these premium step drills?

Each drill bit features a self-starting tip that improves accuracy and control by preventing bit wandering. The TiN coating provides a thermal shield that increases service life and cutting speed, making these drills suitable for tougher materials. A three-flats shank prevents slipping in the drill chuck, and diameter sizes are laser-marked on each step for long-lasting visibility.

Is this set easy to use?

No pilot hole is required, and the bits can also be used to easily enlarge existing holes. The tapered design makes it simple to drill a range of sizes with one bit. They are compatible with most power drills with a standard chuck. Simply secure the bit, apply steady pressure, and drill at the appropriate speed for the material.

Are these step drills suitable for professional use?

Yes, the combination of premium HSS, TiN coating, and self-starting tips makes this set suitable for professional workshops, fabrication, and maintenance tasks. These drills are designed to provide long-lasting, reliable performance and are a popular choice for professionals requiring durable, heat-resistant cutting edges.
