6.3-25mm Countersink Set DIN 335C 90° HSS, 3-Flute, Plastic Case - TECWERK

Take advantage of a precise combination of DIN 335 C conformity, a 90° countersink angle and HSS durability for clean, repeatable hole finishing. The set’s 3-cutting-edge geometry reduces burrs and rework while the compact plastic case keeps tools organised—order directly via Metav Werkzeuge or consult the technical team for application advice.

TECWERK Countersink Set DIN 335 C — HSS countersinks, 90° angle, 6.3–25 mm

A TECWERK Countersink Set DIN 335 C engineered for precision countersinking and deburring of drilled holes in workshop and industrial environments.

• Countersinks DIN 335 C standard
• 3 cutting edges for smooth finish
• 90° countersink angle for common fasteners
• HSS material for robust cutting performance
• Delivered in plastic storage case

Faster, more reliable hole preparation for assembly

The set follows the DIN 335 C specification, ensuring consistent geometry for predictable seating of countersunk fasteners. With a diameter range from 6.3 to 25 mm, the assortment covers typical hole sizes encountered in general workshop and light industrial work. The 90° tip produces the standard chamfer profile required for many screws and rivets, which leads to a reducing of rework and more reliable joint quality. The standardised form also simplifies process planning when multiple operators work on the same parts.

Improved surface finish and reduced burr formation

Each tool features three cutting edges, a geometry that balances cutting action and stability to give a fine surface around the hole. This configuration lowers the risk of tear-out and results in cleaner chamfers with minimal manual deburring afterwards. Made from HSS (high-speed steel), the cutters retain edge hardness at elevated cutting speeds and resist abrasive wear, delivering consistent performance across repeated cycles. The result is a faster throughput for finishing operations and fewer interruptions to replace or regrind tools.

Practical packaging for safe storage and quick access

The kit is supplied in a durable plastic case that organises tools for immediate selection at the machine or bench. Easy identification of each diameter reduces set-up time and helps maintain a tidy workstation, supporting a more efficient workflow. The compact case protects cutting edges during transport and storage, extending tool life and ensuring the set remains ready for precise countersinking and deburring tasks when required.

FAQ

What hole sizes are covered by this countersink set?
The set covers diameters from 6.3 to 25 mm, allowing the TECWERK countersink set to handle common hole sizes for countersinking and deburring operations.

Is the material specification suitable for industrial use?
Yes, the cutters are made from HSS, which provides good hardness and wear resistance for repeated finishing tasks in workshop and light industrial settings.

How does the three-edge geometry affect finish quality?
The three cutting edges of the countersinks create a balanced cutting action that produces a smoother chamfer and reduces burr formation compared with simpler geometries.
