TECWERK Step Drill 4–20 mm, HSS, Spiral Flute

The TECWERK Step Drill 4–20 mm is a precision HSS step drill designed for quick production of stepped holes in thin materials across general workshop and light fabrication applications.

• HSS, precision finish with 2 cutting edges
• Spiral-fluted design for improved chip evacuation
• 118° point angle for reliable centring
• Shank with three flats for secure clamping

Consistent, economical drilling across a range of hole sizes

The spiral-fluted step drill delivers a practical alternative to multiple fixed drills by combining a series of stepped diameters into a single tool. Manufactured in HSS and executed to a precision finish, the tool reduces tool changes and increases throughput when producing holes from 4–20 mm in thin sheet materials. The two cutting edges and the cross-ground geometry promote even cutting forces, which helps to extend tool life and maintain hole quality over repeated cycles.

Cleaner holes and smoother chip flow to cut rework time

A spiral flute profile channels chips away from the cutting zone, improving evacuation compared with straight-flute designs and reducing the risk of clogging. The 118° point angle supports reliable centring on flat surfaces without the need for pilot holes in many applications, while the 90° step geometry produces well-defined step shoulders. Together these features reduce burr formation and secondary finishing, saving time on de-burring and assembly preparation.

Secure mounting and user-friendly handling for reliable results

The shank is supplied with three flats, ensuring stable clamping and minimizing slippage in standard chucks or collets; this is especially useful when torque is variable or when interrupted cuts occur. A 22 mm effective shank length provides compatibility with most bench and pillar drill setups. The precision execution and balanced geometry mean fewer vibrations and improved hole concentricity, which supports tighter tolerances in everyday fabrication and maintenance work.

FAQ

What materials can be drilled with this step drill?
The TECWERK step drill in HSS is suitable for a range of common workshop materials; the combination of HSS and spiral flutes supports drilling in softer metals and many sheet materials where stepped holes are required.

How does the spiral flute help in practical work?
Spiral flutes improve chip evacuation, which reduces clogging and helps maintain hole quality during continuous production with the TECWERK step drill.

Is a pilot hole required for accurate results?
The 118° point angle provides good centring on flat surfaces; in many thin-sheet applications a pilot hole is not essential, though it can further enhance precision for critical tasks.
