TECWERK countersink DIN 335 C, 20.5 mm, 90° — HSS, TiN, 3-flute

The TECWERK countersink DIN 335 C 20.5 mm is a 90° high-speed steel tool designed for clean countersinking and deburring of drilled holes across steel, cast iron and non-ferrous metals.

• HSS construction for high wear resistance
• TiN coating for extended tool life
• Three flutes for rattle-free cutting
• 90° angle for standard countersinking

Precision performance for reliable hole preparation

This tool combines HSS material with a TiN surface finish to deliver consistent cutting performance and longer service intervals. The tool conforms to DIN 335 C, providing a standardised 90° geometry that simplifies set-up and ensures reproducible seat angles for fasteners. The three cutting edges produce a rattle-free cut, reducing chatter and improving surface finish at the hole rim. For workshop planners and production engineers this translates to fewer reworks and steadier cycle times.

Efficient machining across common industrial materials

Engineered for use on steel, cast iron and non-ferrous metals, the countersink offers a practical balance between robustness and versatility. The specification includes a recommended feed of 0.2 mm/rev in steel up to 500 N, which supports predictable metal removal without overloading the tool. The three-flute geometry aids chip evacuation while maintaining concentricity, so burrs are removed cleanly and the hole profile remains true — a clear advantage for assembly-ready components.

Reduced downtime and predictable tool life

The combination of HSS substrate and TiN coating reduces friction and wear, extending the tool’s productive life and cutting costs associated with frequent regrinds or replacements. The cylinder shank provides secure clamping in standard toolholders, minimising runout and helping to preserve the intended 90° countersink shape. For operations that demand repeatable quality, this tool helps maintain throughput while lowering variability in finished parts.

Practical handling and integration into production

Designed for straightforward installation, the countersink fits conventional collets and chucks thanks to its cylinder shank, enabling fast changeovers on drills and machining centres. The tool’s design focuses on delivering a clean chamfer with minimal post-processing, which supports lean workflows and reduces manual deburring. Clear labelling to DIN 335 C and the visible marking of diameter help logistics and toolroom management maintain correct tooling choices on the shop floor.

FAQ

What materials is this countersink suitable for?
The TECWERK countersink is suitable for steel, cast iron and non-ferrous metals, offering clean deburring and chamfering across these common workshop materials.

What is the recommended feed for machining steel?
A practical guideline is 0.2 mm per revolution in steel up to 500 N, which balances cutting efficiency and tool life for the TECWERK countersink.

How many cutting edges does the tool have and why does that matter?
The tool has three cutting edges, which produce a rattle-free cut and improved surface finish compared with two-flute designs, aiding chip control and stability.

Does the tool conform to any industry standard?
Yes, the geometry follows DIN 335 C, guaranteeing standardised 90° countersink dimensions for consistent assembly seats.

What benefits does the TiN coating provide?
The TiN coating lowers friction, increases resistance to wear and can extend the service life of the countersink while improving performance in intermittent or continuous operations.
