TECWERK Countersink DIN 335 C — 90° Ø10.4 mm, HSS TiAlN, 3‑flute

A TECWERK Countersink DIN 335 C designed for precise countersinking and deburring of drilled holes in steel, cast iron and non‑ferrous metals.

• DIN 335 C standardised 90° geometry
• Three‑flute design for chatter‑free cutting
• TiAlN coating for extended tool life
• Cylindrical shank for secure toolholding

Consistent seating and precise geometry for reliable assembly

The DIN 335 C 90° profile guarantees repeatable countersink geometry for reliable screw seating and flush finishes. The standardised angle removes guesswork in assembly design and inspection, while the three‑flute layout promotes a balanced cut that minimises vibration. This leads to a chatter‑free finish and reduces the need for rework, supporting predictable cycle times and higher first‑pass yield in production environments.

Extended tool life and predictable performance under load

Equipped with a TiAlN coating on a high‑speed steel body, this countersink improves thermal resistance and surface hardness compared with uncoated tools. The coating helps maintain cutting edges at elevated temperatures, which extends tool life and preserves edge integrity during higher speed operations. Feed guidance of 0.12 mm/rev in steel (at up to 500 N) offers a reliable starting point for process planning and contributes to stable machining and reproducible results.

Versatile material range for workshop and industrial use

The tool is specified for use in steel, cast iron and non‑ferrous metals in its HSS form; the HSS‑Co variant increases suitability for stainless and heat‑resistant steels. This flexibility reduces tool inventory needs and enables the same countersink design to be applied across diverse workpieces, from structural components to light alloys, without compromising surface finish or concentricity.

Practical features that simplify set‑up and integration

A cylindrical shank provides straightforward clamping in standard toolholders and drill chucks, easing changeovers and setup in busy workshops. Conformity to DIN standard geometry supports process documentation and quality control. The tool comes as single units for targeted replacement and inventory control, making it simple to integrate into existing tool management systems and production routines.

FAQ

Is this countersink suitable for stainless steels?
The TECWERK countersink in its HSS‑Co variant is suitable for stainless and heat‑resistant steels; the standard HSS version is optimised for steel, cast iron and non‑ferrous metals (SKU 2000865224NW).

What advantage does the TiAlN coating provide?
The TiAlN layer increases surface hardness and thermal resistance, which extends the service life of the countersink and maintains edge stability during higher temperature operations.

Which shank type is used and how is it clamped?
The tool features a cylindrical shank, intended for secure clamping in standard drill chucks and toolholders for straightforward changeovers and reliable concentricity.

What feed should be used as a starting point in steel?
A recommended starting feed in steel under loads up to 500 N is 0.12 mm/rev; this parameter supports stable cutting and can be adapted based on machine rigidity and workpiece material.

Can this countersink be used for deburring as well as countersinking?
Yes, the design is suitable for both countersinking and deburring of drilled holes, providing a clean edge and consistent seating geometry.
