Countersink DIN 335 C 90° D 25 mm HSS‑Co, 3 flutes – TECWERK

A Countersink DIN 335 C 90° D 25 mm HSS‑Co designed for precise countersinking and deburring of holes in steel, cast iron and non‑ferrous metals

• DIN 335 C, 90° cutting angle
• Three‑flute design for chatter‑free cutting
• HSS‑Co for stainless and heat‑resistant steel
• Cylindrical shank for secure clamping

Precision cutting for reliable chamfers and deburring

The DIN 335 C geometry combined with HSS‑Co material ensures a stable cutting edge and consistent chamfer forms. The three‑flute layout produces a chatter‑free cut, reducing edge rollover and the need for secondary finishing. This leads to fewer rejects and a steadier process when preparing countersinks for screw seats or clean deburring operations.

Broad material compatibility for mixed production runs

The tool is optimised for use in steel, cast iron and non‑ferrous metals, while the cobalt alloy grade extends performance to stainless and heat‑resistant steels. Compared with standard HSS, the cobalt‑alloy variant maintains hardness at elevated temperatures, so holes remain true under tougher conditions and longer running times, reducing tool change frequency and downtime.

Secure mounting and consistent run‑out behaviour

A cylindrical shank provides straightforward clamping in standard chucks and toolholders, ensuring concentricity and repeatable seating. The even flute spacing improves balance during rotation, which reduces vibration and contributes to a cleaner finish at the hole edge. This design supports stable machine cycles and predictable component fit‑up.

Optimised feed recommendation and process efficiency

Designed with a 90° countersink angle for common fastener seating, the cutter achieves effective material removal at the recommended parameter of 0.2 mm/rev in steel up to 500 N, balancing cutting performance and tool life. The combination of geometry and feed guidance supports efficient single‑pass chamfering and controlled deburring, shortening cycle times in batch and one‑off production.
