TECWERK 90° conical countersink DIN 335 C, Ø16.5 mm, HSS Nano, 3‑flute

The TECWERK 90° conical countersink DIN 335 C is a high‑performance countersinking tool designed for precision finishing of metal and plastic components across workshop and production environments.

• HSS with Nano coating for high wear resistance
• 90° geometry for standard countersinking
• Three‑flute design for smoother operation
• Reduced feed force and extended tool life

Consistent, precise countersinks for production use

The combination of HSS Nano coating and a three‑flute geometry delivers consistently accurate chamfers with minimal burr formation. The specialised chip‑space parameters and variable relief reduce cutting forces, which means the tool demands less feed force while keeping the workpiece surface quality high. In practical terms this results in faster process cycles and fewer reworks when preparing holes for assembly or deburring finished parts.

Faster cycles and measurable productivity gains

Engineered to accelerate the countersinking operation, the tool can achieve up to 30% faster countersinking and up to 60% longer tool life compared with conventional designs, according to the factory data. The optimised geometry also promotes a very quiet, stable run, which improves repeatability across batches and reduces machine wear. For production planners this translates into lower tooling costs per part and greater throughput without compromising accuracy.

Broad material compatibility for one‑tool versatility

Manufactured for versatility, the countersink is suitable for steel, stainless and heat‑resistant steels, aluminium, brass and various plastics. The variable relief and Nano coating help maintain cutting edge performance under thermal and mechanical stress, enabling clean chamfers in mixed‑material assemblies. This single‑tool approach simplifies tooling lists and supports leaner inventory management across repair, maintenance and manufacturing tasks.

Secure clamping and optimised chip evacuation

The tool features a shank with three flats from nominal Ø 8.3 mm, ensuring positive clamping and reliable torque transmission in standard chucks. With right‑hand cutting and engineered chip‑space geometry, swarf evacuation is improved and the countersink runs smoothly even under higher feed loads. The specified feed recommendation in steel is 0.2 mm per revolution at up to 800 N, providing a clear starting point for process setup and stable cycle times.

FAQ

What materials can this countersink handle?
The TECWERK 90° conical countersink is suitable for steel, stainless and heat‑resistant steels, aluminium, brass and a range of plastics, thanks to its HSS substrate and Nano coating.

How should cutting parameters be set for steel?
As a reference, the countersink performs well at a feed of 0.2 mm per revolution with cutting forces up to 800 N; actual settings should be adapted to machine rigidity and workpiece conditions.

What advantage does the Nano coating provide?
The Nano coating increases wear resistance and hot hardness, extending tool life and maintaining edge stability during repeated countersinking cycles.

Why choose a three‑flute design over two‑flute?
The three‑flute geometry delivers smoother operation and improved surface finish while enhancing chip control and reducing vibration compared with two‑flute variants.

Is the shank suitable for standard toolholders?
Yes, the shank is supplied with three flats from nominal Ø 8.3 mm for secure clamping in common chucks and holders.
