31mm 90° Countersink 3-Flute HSS-Co Cylindrical Shank, 0.22mm/rev Feed in Steel - TECWERK

Combining the DIN 335 C geometry, a 90° countersink angle and a HSS‑Co substrate, this tool provides precise, rattle‑free chamfering and consistent service in stainless and heat‑resistant steels; order the TECWERK countersink directly via Metav Werkzeuge or consult the technical team for tailored application advice.

TECWERK Countersink DIN 335 C Ø31 mm — 90° HSS‑Co, 3‑flute

The TECWERK Countersink DIN 335 C Ø31 mm is a three‑flute, cylindrical‑shank cutting tool designed for reliable countersinking and deburring of drilled holes across a wide range of metals.

• DIN 335 C standard compliance
• 90° countersink angle for chamfers
• Three‑flute, rattle‑free cutting
• HSS‑Co for stainless and heat‑resistant steel

High‑precision countersinking for consistent process results

The TECWERK countersink combines a standardised DIN 335 C geometry with a 90° taper to produce uniform chamfers and deburrs that meet assembly requirements. The 3‑flute configuration delivers a rattle‑free cut, which reduces chatter and improves surface finish compared with two‑flute variants. With a specified feed 0.22 mm/rev in steel up to 500 N, the tool offers predictable material removal rates that support stable cycle times and reproducible hole preparation in production environments.

Material performance and application range explained

Manufactured in HSS‑Co, the cutter is suited to a broad material spectrum: steel, cast iron and non‑ferrous metals, with an extended capability for stainless and heat‑resistant steels thanks to the cobalt alloy. In practical terms, HSS‑Co increases red hardness and wear resistance, so the tool retains cutting geometry and edge life under higher temperatures. This makes the product economical over many cycles where conventional high‑speed steel would wear prematurely.

Practical design for workshop integration and tool life

The cylindrical shank enables straightforward mounting in standard chucks and toolholders, simplifying changeover and set‑up. The geometry is optimised for countersinking and deburring, delivering clean chamfers that ease subsequent assembly and reduce rework. As a result, maintenance intervals can be extended and tool replacement scheduled predictably. For operations seeking to standardise tooling and minimise process variation, this countersink supports stable quality and repeatability on mixed metal batches.

FAQ

What materials can this countersink process effectively?
The TECWERK countersink is suitable for steel, cast iron and non‑ferrous metals and, due to its HSS‑Co composition, is also appropriate for stainless and heat‑resistant steels.

How does the three‑flute design benefit machining?
A three‑flute geometry provides a stable, rattle‑free cutting action that improves surface finish and reduces vibration compared with fewer flute designs when countersinking holes.

What mounting system is required for this tool?
The tool features a cylindrical shank, enabling clamping in standard chucks or holders commonly used in drilling and milling equipment.

Is the countersink compliant with industry standards?
Yes, the design conforms to DIN 335 C, ensuring consistent geometry and compatibility with standard chamfer requirements.

What feed rates are recommended for steels?
For steels up to 500 N, the specified feed is 0.22 mm per revolution, providing a balance between cutting efficiency and tool life.
