TECWERK conical countersink DIN 335 C, 90° D25 mm – HSS TiAlN, 3 flutes

The TECWERK conical countersink DIN 335 C is a precision tool for chamfering and deburring drilled holes in steel, castings and non‑ferrous metals, designed for industrial workshop and production environments

• DIN 335 C geometry, 90° chamfer angle
• Three‑flute design for chatter‑free cut
• TiAlN coating for heat resistance
• Suitable for steel, castings and non‑ferrous metals

Consistent chamfers and reduced rework with standardised geometry

The DIN 335 C specification and 90° chamfer angle ensure repeatable chamfers that match standard fastener and countersink profiles, which reduces assembly adjustments and rework. The three‑flute geometry gives a more even cutting action than two‑flute designs, producing a chatter‑free finish and smoother edges. The tool’s cylindrical shank allows simple mounting in common toolholders and drill chucks, so process integration is straightforward and operator training is minimal. These characteristics support steady throughput in batch production.

Extended tool life and thermal stability for demanding applications

Constructed in HSS with a TiAlN coating, the tool offers improved wear resistance and thermal protection during higher temperatures. The coating forms a stable, hard surface that reduces adhesion of workpiece material and delays softening, which translates into longer service intervals and less downtime for tool changes. Where machining stainless or heat‑resistant steels is required, the HSS‑Co alternative provides higher red hardness; the distinction between HSS and HSS‑Co helps specify the correct grade for each workpiece material, ensuring process reliability and cost efficiency.

Practical machining guidance for efficient use and safe operation

Designed for both chamfering and deburring, the countersink delivers clean edges on drilled holes in steel, cast iron and non‑ferrous metals, improving fastener seating and component fit. The manufacturer recommends a feed in steel up to 500 N with 0.2 mm/rev, a guideline that balances cutting forces and surface finish; adjust spindle speed and feed to match material and machine rigidity. The tool’s construction minimises vibration, which preserves component tolerances and cutting edge geometry, helping production engineers achieve predictable results and lower scrap rates.

FAQ

What materials is the TECWERK countersink suitable for?
The TECWERK countersink is specified for chamfering and deburring in steel, castings and non‑ferrous metals; HSS‑Co grades extend capability to stainless and heat‑resistant steels.

How does the TiAlN coating benefit tooling performance?
TiAlN on this countersink increases heat resistance and wear protection, which prolongs tool life and improves performance under higher cutting temperatures.

What does the three‑flute design change compared with two flutes?
Three flutes deliver a more continuous cutting action, reducing vibration and producing a smoother, chatter‑free finish on the chamfer edge.

What is the recommended feed for chamfering steel with this tool?
The published guideline indicates a feed in steel up to 500 N of 0.2 mm/rev; actual settings should be adapted to machine rigidity and workpiece conditions.

Is this countersink compatible with standard drill chucks and holders?
Yes, the cylindrical shank is suitable for common toolholders and drill chucks used in workshop and production environments.
