TECWERK conical countersink DIN 335 C, 90° Ø15 mm — HSS‑Co, 3‑flute

A TECWERK 90° conical countersink designed for clean chamfering and deburring of drilled holes in steel, castings and non‑ferrous metals

• DIN 335 C standard compliance
• Three‑flute rattle‑free cutting action
• HSS‑Co for stainless and heat‑resistant steels
• Cylindrical shank for standard chucks

Reduce rework with a rattle‑free three‑flute design

The three‑flute geometry delivers a steady, low‑vibration cut that reduces chatter and produces a cleaner chamfer compared with two‑flute countersinks. For workshop managers this means fewer rejected parts and less finishing time, because the tool produces a predictable edge and minimal burr formation. The combination of DIN 335 C geometry and a 90° angle ensures interchangeability with fixtures and predictable chamfer dimensions, while the cylindrical shank fits standard collets and chucks for straightforward set‑up.

Work reliably across common workshop materials

This countersink is offered in HSS‑Co, which extends performance into stainless and heat‑resistant steels, while the general HSS variant suits standard steels, cast iron and non‑ferrous metals. The specification explicitly lists suitability for steel, cast iron and non‑ferrous metals, so operators can select the correct grade for their application and expect consistent edge quality. The provided feed guidance — 0.14 mm/rev in steel up to 500 N — gives a practical starting point for process planning and reduces trial‑and‑error during setup.

Consistent results and simple process integration

A tool that cuts smoothly lowers operator strain and improves cycle stability; the rattle‑free cut produced by the three cutting edges reduces noise and extends tool life by equalising wear. The HSS‑Co substrate offers improved hot‑hardness for higher cutting temperatures, which is beneficial when countersinking tougher alloys. Because the countersink conforms to DIN 335 C, it integrates easily into existing production sequences without bespoke fixturing — a pragmatic choice for shops that prioritise uptime and reproducible quality.

Practical guidance for setup and use

For best results run the countersink at speeds and feeds appropriate to the material and machine rigidity; the published feed of 0.14 mm/rev in steel up to 500 N provides a reference for manual and CNC operations. The cylindrical shank supports quick tool changes and stable clamping, while the three‑cut design promotes a balanced load on the tool body. Operators unfamiliar with the specification can rely on the standardised 90° geometry to match common countersinking applications such as chamfering for countersunk screws and deburring drilled through‑holes.

FAQ

What materials can be processed with this countersink?
The TECWERK conical countersink DIN 335 C, 90° Ø15 mm (SKU 2000865008NW) is suitable for steel, cast iron and non‑ferrous metals; the HSS‑Co grade extends capability into stainless and heat‑resistant steels.

How does the three‑flute design affect finish quality?
The three‑flute arrangement on the TECWERK countersink produces a rattle‑free cut that reduces chatter and yields a cleaner chamfer, helping to minimise subsequent deburring or rework.

Is this tool compatible with standard chucks and holders?
Yes — the countersink features a cylindrical shank and conforms to DIN 335 C, allowing straightforward clamping in standard collets and chucks for consistent positioning.

What feed rate should be used for steel?
The specification for the TECWERK 90° countersink indicates a reference feed of 0.14 mm/rev in steel up to 500 N, which serves as a practical starting point for machining trials.

Can the same countersink be used on stainless steel?
The HSS‑Co version of this TECWERK countersink is engineered for stainless and heat‑resistant steels; the cobalt alloy improves hot‑hardness and wear resistance under higher cutting temperatures.
