12.4mm Countersink DIN 335C 90° HSS 3-Flute Cylindrical Shank, 0.14mm/rev Steel Feed - TECWERK

Take advantage of the HSS three‑flute geometry and the 90° DIN 335 C profile for reproducible, chatter‑free countersinking in steel, cast iron and non‑ferrous metals; for availability and advice, order the tool via Metav Werkzeuge or consult the technical team.

Countersink DIN 335 C, 90° Ø12.4 mm, HSS, 3‑flute (TECWERK) — Countersink for clean chamfering and deburring

The Countersink DIN 335 C, 90° Ø12.4 mm, HSS, 3‑flute is a cylindrical‑shank countersink engineered for consistent chamfering and deburring of drilled holes across ferrous and non‑ferrous materials.

• HSS, DIN 335 C, 3 flutes
• 90° countersink angle
• Ø12.4 mm cutting diameter
• Cylindrical shank for secure mounting

Consistent, chatter‑free countersinking that speeds production

The TECWERK countersink combines a hardened HSS body with a 3‑flute geometry conforming to DIN 335 C, delivering a chatter‑free cutting action and a reproducible chamfer. The 90° cone angle produces the standard countersink profile required for many fasteners and fits, while the Ø12.4 mm cutting diameter keeps tolerances tight in serial production. Where repeatability and surface quality are critical, the three‑flute design reduces vibration and improves chip evacuation compared with two‑flute variants, resulting in fewer rework cycles and a higher first‑pass yield.

Secure set‑up and measurable process parameters for reliable cycles

A cylindrical shank ensures secure clamping in standard chucks and tool holders, supporting steady rotation and stable axial alignment during operation. The tool’s measurable guidance — feed in steel up to 500 N: 0.14 mm/rev — offers a concrete parameter for process planning and CNC cycle programming, enabling efficient integration into existing machining sequences. For workshops and maintenance departments the result is a clearer edge finish and reduced manual deburring, which shortens throughput times and lowers overall processing costs.

Practical application scope and machining advice for safe use

Designed for countersinking and deburring of holes, the countersink is suitable for steel, cast iron and non‑ferrous metals, making it a versatile choice for toolrooms and production lines alike. The DIN 335 C designation standardises the cone geometry, simplifying tool selection for assemblies that require a 90° chamfer. The HSS material balances edge retention and toughness for general‑purpose use; the three‑flute profile enhances surface quality and chip control, particularly on interrupted or slightly misaligned holes. For best results, match shank fixation to the machine and maintain steady feed rates in accordance with the stated feed recommendation.
