TECWERK Countersink DIN 335C, 90° — 8.3 mm HSS with TiN, 3‑flute

The TECWERK Countersink DIN 335C 90° (8.3 mm) is a precision countersink designed for clean countersinking and deburring of drilled holes in steel, cast iron and non‑ferrous metals, ideal for production and workshop use

• HSS with TiN coating for enhanced wear resistance
• DIN 335C profile with precise 90° geometry
• Three flutes for chatter‑free surface finish
• Cylindrical shank for secure clamping

Consistent edge geometry for precise seating

The countersink’s DIN 335C profile and 90° angle ensure predictable chamfer geometry, which simplifies assembly and fastener seating. Manufactured from HSS, the tool provides the toughness required for intermittent and continuous operation, while the TiN coating reduces friction and improves tool life under normal workshop conditions. The three‑cut design contributes to a uniform cutting action, reducing the need for subsequent rework and supporting more consistent part quality.

Faster, chatter‑free finishing that sustains throughput

A three‑flute layout delivers a smoother chip formation and a chatter‑free cut compared with two‑cut alternatives, enabling reliable surface finishes at production speeds. The tool’s specified feed characteristic of 0.09 mm/rev in steel (up to a cutting resistance of 500 N) provides a practical starting point for process set‑up, allowing operators to balance surface finish and cycle time. These traits translate directly into higher throughput and fewer rejects on repetitive countersinking tasks.

Versatile for common workshop materials and secure clamping

Designed for operation on steel, cast iron and non‑ferrous metals, the countersink covers a broad range of typical workshop applications, from mechanical assembly to maintenance work. The cylindrical shank ensures positive seating in standard drill chucks and collets, which aids concentricity and reduces runout. Using a tool with predictable shank and geometry characteristics simplifies fixturing and reduces setup variability across batch runs.

Practical handling and straightforward tool care

The combination of HSS substrate and TiN coating gives a balance of toughness and wear resistance suitable for general countersinking duties. Regular inspection of the cutting edges and keeping the tool free of built‑up material will help preserve finish quality; when wear is evident, replacement restores original performance quickly. The compact 8.3 mm diameter and standard shank format support easy integration into existing tooling stock without special holders.
