TECWERK countersink DIN 335 C, 90° D16.5 mm — HSS, TiN, 3-flute

The TECWERK countersink DIN 335 C 90° D16.5 mm is a robust, production-oriented tool for countersinking and deburring holes in steel and non-ferrous materials, designed for fast, clean chamfering in workshop and industrial environments.

• HSS solid construction, DIN 335 C
• 90° countersink angle for standard fittings
• TiN coating for extended tool life
• Three-flute design ensures rattle-free cut

Precise chamfers with consistent surface quality

Made from HSS, this countersink delivers repeatable results when producing chamfers and preparing holes for fasteners. The 90° geometry matches standard screw and bolt heads, while the 16.5 mm diameter provides a typical chamfer size suitable for many fastening operations. The three flutes stabilise the cutting action and produce a rattle-free cut, which reduces chatter marks and the need for rework. For operators less familiar with cutting data, the tool’s DIN 335 C specification offers a clear reference that simplifies tool selection and ensures interchangeability in production processes.

Longer tool life and reduced machine downtime

The TiN coating reduces wear and improves resistance to built-up edge when machining steels and non-ferrous alloys, extending service intervals and lowering tool replacement frequency. The cylindrical shank ensures secure clamping in standard toolholders and contributes to consistent concentricity during operation. Measured feed performance shows that at loads up to 500 N the recommended feed is around 0.14 mm per revolution, a practical value for balancing surface finish and productivity. This combination of durable materials and stable geometry means fewer changeovers and a smoother production flow.

Easy integration into workshop workflows

Conforming to DIN 335 C, the countersink fits established process standards and can be integrated without altering existing fixtures or assembly steps. Its application range — countersinking and deburring for steel, cast iron and non-ferrous metals — makes it a versatile choice for maintenance shops and fabrication cells alike. The three-flute design not only improves finish but also permits higher feed rates where appropriate, helping to shorten cycle times. Supply and quality assurance are supported by established distribution channels, with Metav Werkzeuge providing centralised availability and a proven track record in precision tools for industrial users.

FAQ

Which materials can be machined with this countersink?
The TECWERK countersink (DIN 335 C, SKU 2000865198NW) is suitable for steel, cast iron and non‑ferrous metals, as indicated by the tool’s HSS substrate and TiN coating.

What is the angle and diameter of the countersink?
The tool has a 90° countersink angle and a 16.5 mm cutting diameter, matching common fastening and chamfering requirements.

How does the TiN coating benefit workshop performance?
The TiN coating on this TECWERK countersink improves wear resistance and reduces built-up edge, which extends tool life and supports more consistent surface quality.

Are there recommended feed values for this tool?
At loads up to 500 N a practical feed is about 0.14 mm per revolution; actual settings depend on machine rigidity and workpiece material.

What feature reduces vibration and chatter during cutting?
The three-flute geometry provides a stabilised cutting action that results in a rattle-free cut and improved surface finish.
