Sheet Metal Step Drill Set 3–14 / 4–20 / 16–30.5 mm, HSS‑Co (3 pcs) – TECWERK

The Sheet Metal Step Drill Set 3–14 / 4–20 / 16–30.5 mm HSS‑Co (3 pcs) is a compact trio of step drills designed for efficient hole enlargement and clean entry in thin metalwork and maintenance applications

• HSS‑Co cobalt for high cutting performance
• Shanks with three clamping flats for firm grip
• Diameter ranges 3–14, 4–20, 16–30.5 mm covered
• Supplied in a plastic storage case

Faster workflows and fewer tool changes with step geometry

The set's HSS‑Co composition provides improved heat resistance and wear behaviour compared with standard high‑speed steels, which supports sustained performance during repeated hole enlarging tasks. The step geometry integrates several diameters in a single flute profile, allowing continuous enlargement of holes without changing tools; this reduces downtime and simplifies process planning in repair and light production environments. The diameter ranges 3–14 mm, 4–20 mm and 16–30.5 mm are arranged to cover common sheet‑metal requirements, enabling efficient progression from pilot holes to finished sizes.

Reliable clamping for consistent hole quality

Each bit features a shank with three clamping flats, which prevents rotation in the chuck and improves concentricity. Secure clamping reduces vibration and runout, resulting in cleaner hole edges and longer tool life. This mechanical stability is particularly relevant when working with thin materials where precision and a burr‑reduced finish matter; operators benefit from repeatable results and fewer rework cycles, improving overall workshop throughput.

Practical storage and organisation to protect tools

The set is supplied in a robust plastic storage case, designed for orderly storage and easy identification on a busy tooling board. The compact cassette protects cutting edges during transport and keeps the three‑piece set accessible at the point of use. Better organisation supports faster set‑up times and helps maintain serviceable condition for longer, lowering total operating effort and supporting a tidy workstation ethos.

Clear use cases and straightforward handling for everyday tasks

Step drills of this type are ideally suited to enlarging and deburring pre‑punched holes, producing clean entry holes in thin panels and performing temporary or permanent assemblies in maintenance, HVAC and fabrication tasks. The working principle is simple: progressive steps cut incrementally to the desired diameter, reducing torque spikes and the need for pilot reaming. With proper clamping and moderate feed rates, this tool trio delivers consistent hole quality and is an efficient complement to a small industrial or trade workshop's tooling set.

FAQ

What materials are these step drills intended for? The TECWERK step drill set is optimised for sheet‑metal operations and similar thin‑gauge tasks where progressive hole enlargement and clean entry are required.

How does the three‑flat shank influence performance? The shank with three clamping flats reduces rotation in the chuck, improving concentricity and producing more consistent holes with less vibration when using the TECWERK set.

Is the set convenient for workshop storage and transport? Yes, the three‑piece set is supplied in a plastic cassette that protects cutting edges, simplifies identification and keeps tools organised for fast access.

Can one tool replace several conventional drills? Step drills in this set combine multiple diameters in a single body, enabling the progressive enlargement of holes and reducing the need to change conventional twist drills during many sheet‑metal tasks.
