TECWERK 90° Countersink DIN 335C, Ø 8.3 mm — HSS‑Co, TiAlN, 3‑flute

The TECWERK 90° countersink DIN 335C is a spiral‑fluted, three‑cutting‑edge countersink designed for precise deburring and chamfering across a wide range of metals and plastics

• HSS‑Co substrate for long tool life
• TiAlN coating for thermal and wear resistance
• 90° angle for standard chamfer profiles
• Spiralised 3‑flute geometry for smooth cutting
• Reduced feed and radial forces for accurate finishes

Faster, cleaner chamfers for mixed materials

The TECWERK 90° countersink DIN 335C combines a HSS‑Co substrate with a TiAlN surface treatment and a spiralised 3‑flute geometry to deliver consistently round, exact and rattle‑free countersinks. The spiralised cutting edges promote reliable chip evacuation and reduce vibration, which results in a cleaner edge and fewer rejects. Measured process improvements include up to 60% lower feed force and 50% lower radial force, translating directly into less strain on fixtures and improved surface quality.

Longer tool life and stable cutting behaviour

A cobalt‑alloy HSS‑Co body provides mechanical strength at elevated temperatures, while the TiAlN coating increases oxidation resistance and hardness at cutting temperatures. This pairing supports higher cutting speeds and longer intervals between tool changes, delivering predictable uptime. For production environments where tool change overheads impact throughput, the enhanced wear resistance reduces maintenance cycles and contributes to lower total operating cost.

Process control and straightforward machining parameters

Conforming to DIN 335C and fitted with a cylindrical shank, the tool is compatible with standard collets and holders, easing integration into existing setups. The spiral, convex‑cutting geometry is right‑hand cutting and is suitable for a broad material spectrum — from mild steel and stainless variants to aluminium, brass and engineering plastics. Recommended feed setting in steel up to 800 N is 0.105 mm/rev, providing a baseline for process planners to tune feed and speed for material‑specific optimisation.

Seamless production adoption and quality assurance

Designed for workshop and industrial use, the countersink’s construction yields consistently good visual and tactile chamfer results, reducing downstream rework. The combination of stable cutting forces and improved chip control allows integration into automated cell machining as well as manual operations. For buyers seeking supply reliability and a broad portfolio, Metav’s distribution from Emmerich functions as a quality filter for European customers, ensuring consistent stock and professional advice when scaling machining processes.

FAQ

Which materials can be machined with this countersink?
The TECWERK 90° countersink DIN 335C machines steel, stainless and heat‑resistant steels, aluminium, brass and a range of engineering plastics as stated in the product data (SKU 2000865291NW).

What benefit does the TiAlN coating provide?
The TiAlN coating on this countersink increases thermal resistance and surface hardness at cutting temperatures, improving wear resistance and extending the tool life of the TECWERK countersink.

How does the spiralised 3‑flute geometry help production?
Spiralised flutes and unequal convex cutting edges improve chip evacuation and reduce vibration, resulting in smoother chamfers and reduced radial and feed forces during machining.

Is the shank compatible with common collet systems?
Yes — the cylindrical shank conforms to standard collet holders, enabling straightforward mounting in typical manual and CNC toolholders for process integration.

What feed settings are recommended as a starting point?
A baseline recommendation given for steel (up to 800 N) is 0.105 mm/rev; fine tuning of feed and speed should be performed according to material grade and machine stability.
