Take advantage of the HSS‑TiN coating and the robust three‑clamp flat shank to boost drilling speed and tool life; the compact plastic cassette keeps the set organised and ready for workshop use. Order the set directly via Metav Werkzeuge or ask the Metav consultants for application advice.

TECWERK sheet metal step drill set, HSS‑TiN, 3‑piece (3–30.5 mm ranges)

The TECWERK sheet metal step drill set is a three‑piece solution for precise hole making and fast deburring in thin metal workpieces, supplied in a practical plastic cassette.

• HSS‑TiN coating for extended wear resistance
• Step coverage 3–30.5 mm across three drills
• Shank with 3 clamping flats for secure grip
• Supplied in a plastic cassette for tidy storage

Faster, cleaner drilling for sheet‑metal production

The set delivers consistent step diameters across three versatile ranges, enabling quick progression from pilot to final hole size without tool changes. The HSS‑TiN coating reduces friction and increases surface hardness, which lowers tool wear and supports higher cutting speeds in routine sheet‑metal tasks. For production environments, this translates into fewer interruptions, improved cycle times and a predictable finish quality on thin plates. The design reduces burr formation by producing more uniform cutting conditions, so time spent on secondary deburring is minimised and throughput is optimised.

Stable clamping and reduced run‑out for precision results

A shank with three clamping flats ensures reliable seating in chucks and adapters, reducing slippage and run‑out that can spoil hole geometry. Secure clamping means the bit maintains its concentricity during operation, which is particularly important when enlarging existing holes or stepping through multiple diameters. The three‑flat arrangement facilitates quick, repeatable setup in both standard chucks and quick‑change holders, supporting faster tool changes and a safer working environment. Accurate positioning leads to fewer rejects and less rework, improving overall efficiency on the shop floor.

Practical storage, handling and workshop reliability

The three‑piece kit comes held in a plastic cassette that keeps tools organised and protected between jobs, simplifying transport and storage at the bench. Compact storage reduces the risk of lost cutters and ensures the right size is at hand when needed. The set’s combination of durable coating and robust shank geometry means a long service life under typical sheet‑metal workloads, contributing to predictable maintenance intervals and cost‑effective operation. The brand’s focus on dependable workshop tools makes this set suitable for both trade and light industrial applications, where straightforward tool management and consistent performance are valued.

FAQ

What sizes are included in the set?
The TECWERK sheet metal step drill set (SKU 2000862055NW) contains three step drills covering ranges 3–14 mm, 4–20 mm and 16–30.5 mm.

What is the coating and why does it matter?
The cutters feature an HSS‑TiN coating; this increases surface hardness and reduces friction, extending tool life and allowing higher cutting speeds in typical sheet‑metal work.

Will the shank fit standard chucks and holders?
Yes — the shank with three clamping flats provides a secure grip in standard drill chucks and many quick‑change holders, improving concentricity and reducing slippage during operation.

Which materials is the set intended for?
The set is designed for sheet metal and thin plate applications; it is optimised for clean holemaking and efficient step drilling in such materials.

How should the drills be stored and maintained?
Keep the tools in the supplied plastic cassette to protect edges and store them dry; clean chips after use and inspect cutting edges for wear to determine re‑grinding or replacement.
