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

The TECWERK Countersink Set DIN 335 C is a three-flute countersink designed for precise chamfering and deburring of drilled holes in workshop and light industrial environments

• DIN 335 C geometry for consistent chamfers
• 90° countersink angle for standard fittings
• HSS with TiAlN coating for extended tool life
• Supplied in a compact plastic case

Consistent geometry for repeatable results

The DIN 335 C specification ensures a standardised cutting form that produces uniform chamfers across batches. The 90° angle meets common assembly requirements and simplifies downstream fitting and countersunk fastener seating. By using tools conforming to this geometry, process variance is reduced and part interchangeability is improved, which supports predictable assembly tolerances and fewer reworks in production.

Fast material removal with clean edges

A three-flute design provides a balance between cutting speed and surface finish: it removes material efficiently while maintaining a controlled cutting action that reduces burr formation. The combination of HSS substrate and TiAlN coating enhances thermal resistance and wear performance, allowing longer runs before regrinding is required. This results in fewer tool changes and better uptime on small-batch and repetitive tasks.

Practical set composition and secure storage

The set covers a 6.3–25 mm diameter range, offering a versatile spread of sizes for common workshop needs. Supplied in a sturdy plastic case, the kit keeps cutters organised and protected from damage during transport or storage. Clear organisation reduces search time and supports a tidy workbench, contributing to faster job changeovers and improved workflow in busy work environments.

Suitable for routine chamfering and deburring tasks

Designed specifically for chamfering and deburring drilled holes, the cutters give a clean edge suitable for both metalworking and many non-ferrous materials where standard countersinking is required. The geometry and coating combination offers a pragmatic compromise between cost and performance, making the set appropriate for maintenance shops, toolrooms and small production lines seeking dependable, repeatable results.
