Take advantage of HSS‑Co substrate and TiAlN coating for extended tool life and lower cutting forces; the 90° DIN 335 C geometry delivers round, chatter‑free countersinks across a wide range of materials — order directly via Metav Werkzeuge or contact our consultants for application advice.

TECWERK Countersink set DIN 335 C 90° — HSS‑Co, TiAlN, 6.3–25 mm

The TECWERK Countersink set DIN 335 C 90° is a precision cutting tool set for standardised countersinking and deburring in metalworking and general workshop use

• TiAlN coating for extended tool life
• HSS‑Co base for high cutting endurance
• 90° DIN 335 C for standardised countersinks
• Reduced feed and radial forces for smooth cuts

Consistent precision and far longer tool life for production use

The combination of a HSS‑Co substrate with a TiAlN coating provides high thermal resistance and wear protection, translating into longer service life and fewer tool changes. The tools' spiralised flutes and three unequal convex cutting edges reduce chatter and produce round, accurate countersinks; this reduces rework and improves cycle reliability. For production environments, the lower feed and radial forces mean less power draw and smoother insertion, supporting a predictable processing workflow and higher throughput.

Universal suitability across common engineering materials

Designed to process steel, stainless and heat‑resistant steels, aluminium, brass and a range of plastics, the set combines material versatility with DIN‑standard geometry. The 90° angle conforms to DIN 335 C, ensuring compatibility with standard fasteners and reducing fitting errors. The right‑hand cutting action and spiral flute geometry aid chip evacuation, which helps maintain surface finish and reduces the risk of edge build‑up on the tool.

Easier handling, cleaner holes and organised storage

Reduced feed and radial forces result in quieter, chatter‑free countersinking and a finer finish, particularly important for visible assemblies and precision components. Spiral flutes assist chip removal to prevent clogging when machining softer alloys and plastics. The kit is supplied in a practical plastic case for secure storage and quick tool selection at the bench, keeping tooling organised and ready for repeatable results.
