Countersink DIN 335 C Ø16.5 mm — HSS, TiAlN, 3‑flute (TECWERK)

The Countersink DIN 335 C Ø16.5 mm (90°) is a robust cutting tool for clean countersinking and deburring of drilled holes in steel, castings and non‑ferrous materials, designed for production and workshop use.

• Countersink DIN 335 C, 90° cutting angle
• Three‑flute design for chatter‑free cutting
• TiAlN coating for increased wear resistance
• Cylindrical shank for secure toolholding

Consistent chamfers for reliable assemblies

A repeatable 90° chamfer is the basis for accurate screw seating and finished part appearance. The tool’s geometry follows DIN 335 C, delivering a uniform chamfer that reduces rework and assembly time. The three‑flute configuration distributes cutting forces evenly, which results in a chatter‑free cut and a smooth edge that minimises secondary finishing. For production environments this translates to higher first‑pass yield and fewer manual touch‑ups.

Durable performance under higher loads

The substrate of the tool is HSS with a TiAlN surface treatment, combining toughness with high surface hardness. This pairing improves tool life under intermittent cutting and at elevated temperatures, so the countersink maintains edge quality over many cycles. The TiAlN coating reduces adhesive wear and supports dry or reduced‑lubrication processes, extending service intervals and lowering tooling costs per component.

Clear operating guidance for efficient machining

The countersink is supplied with a cylindrical shank for standard toolholders and is suitable for countersinking in steel, cast iron and non‑ferrous metals. Recommended feed in steel up to 500 N is 0.14 mm/rev, which balances surface finish and tool life for many workshop applications. Following these parameters helps to maintain the geometry and avoid premature wear while preserving a clean deburred edge.

Practical benefits for workshops and production

The combination of standardised geometry, proven substrate and coating makes this countersink a pragmatic choice for workshop managers and CNC operators who require predictable results. With conformity to an established standard and a design that reduces vibration, the tool supports consistent component quality, reduced cycle variability and easier quality control sampling on the shop floor.
