TECWERK tapered countersink DIN 335 C — 25 mm, HSS‑Co, TiAlN coating

TECWERK tapered countersink DIN 335 C, 90° — a precision chamfering tool for steels, aluminium, brass and plastics

TiAlN coating for extended tool life
HSS‑Co substrate for heat resistance
Spiral flutes for chatter‑free cutting
Suitable for steels, non‑ferrous metals and plastics

Precision chamfering that reduces machining forces

The TECWERK tapered countersink is designed to produce clean, concentric chamfers with minimal vibration. Its three unequal convex cutting edges and spiral flutes distribute cutting forces and reduce tendency to chatter; this results in 60% lower feed force and 50% lower radial force compared with conventional straight‑flute countersinks. The 90° taper and consistent geometry guarantee repeatable chamfer dimensions and a predictable finish, which helps maintain assembly tolerances and reduces rework in production environments.

Durable combination of substrate and coating for extended tool life

Built from HSS‑Co (cobalt‑alloyed high‑speed steel) and finished with a TiAlN coating, the tool resists heat and abrasive wear during high‑duty cycles. TiAlN provides an oxidised protective layer that withstands elevated cutting temperatures and reduces built‑up edge on non‑ferrous materials. For shops transitioning between batch sizes, the improved wear resistance translates into longer intervals between tool changes and lower overall tooling consumption, supporting stable process economics.

Wide material compatibility and straightforward process parameters

The geometry and material selection enable use across a broad material range: carbon and alloyed steels, stainless and heat‑resistant steels, aluminium, brass and various plastics. The tool is right‑hand cutting with a cylindrical shank for simple mounting in standard toolholders or collets. For steels up to a cutting resistance of 800 N the recommended feed is 0.160 mm per revolution, offering a clear starting point for process setup; adapt feeds for softer materials such as aluminium to achieve the preferred surface finish without excessive tool load.

Consistent integration into workshop and CNC workflows

The countersink conforms to DIN 335 C (Form C), which facilitates interchangeability and process planning in professional workshops. The 25 mm diameter and standard shank fit common countersinking operations on drilling machines and machining centres. Because the tool is designed for predictable, rounded chamfers and rattle‑free performance, it reduces cycle variability and supports higher first‑pass yields — a practical advantage for production and maintenance tasks alike.

FAQ

What diameter and angle does this countersink have?
The TECWERK tapered countersink is specified with a 25 mm diameter and a 90° chamfer angle in accordance with DIN 335 C.

Which materials can this countersink machine reliably?
The tool machines carbon and alloyed steels, stainless and heat‑resistant steels, aluminium, brass and various plastics, thanks to the HSS‑Co substrate and TiAlN coating.

How does the TiAlN coating help in practice?
TiAlN extends tool life by providing thermal and abrasive resistance; on the TECWERK countersink this reduces built‑up edge and preserves cutting geometry during elevated temperatures.

What feed should be used for steel applications?
A recommended starting feed for steels with cutting resistance up to 800 N is 0.160 mm per revolution; adjust feed rates for different materials to optimise finish and tool life.

Is the geometry suitable for CNC and manual drilling machines?
Yes — the cylindrical shank and DIN 335 C Form C geometry make the countersink compatible with standard toolholders used in both CNC machining centres and manual drilling setups.
