Countersink Set DIN 335 C 90° 6.3–20.5 mm, HSS‑Co — TECWERK

The countersink set DIN 335 C is an HSS‑Co tool designed for accurate countersinking and deburring of drilled holes in metalworking and workshop applications

• DIN 335 C standard compliance
• 90° countersink angle for common fasteners
• Three cutting edges for smooth surface finish
• HSS‑Co composition for higher wear resistance
• Plastic cassette for organised storage

Precision that reduces rework and cycle time

The set conforms to DIN 335 C, ensuring a defined geometry that produces consistent chamfers and countersinks. The 90° angle matches common screw heads and creates predictable seating for fasteners, reducing the need for rework. With the three cutting edges, material removal is even and generates a finer finish than two‑flute variants, which lowers subsequent finishing time. This predictable behaviour supports efficient process planning and reduces scrap rates in routine machining tasks.

Material choice for longer tool life and stability

Manufactured from HSS‑Co (cobalt alloyed high‑speed steel), the cutters offer improved hot hardness and wear resistance compared with standard HSS. The alloy composition helps maintain cutting geometry under higher temperatures and intermittent loading, which prolongs service intervals and lowers tooling costs per part. The result is greater uptime and fewer tool changes in repetitive workshop operations, translating into measurable productivity gains for everyday metalworking tasks.

Organised storage for fast access and safe handling

Supplied in a practical plastic cassette, the tools remain protected and easy to transport between workstations. Compact storage reduces loss and prevents damage to the cutting edges, preserving the tool geometry that is essential for consistent countersinking and deburring results. Clear organisation of tools also speeds up job changeovers and supports a tidy workplace, contributing to safer and more efficient daily operations.

Clear application and measurable benefits

Designed specifically for countersinking and deburring of drilled holes, this TECWERK solution provides a robust, standardised approach to preparing holes for fasteners and finishing edges. The combination of standard conformity, cobalt‑alloy steel and three‑edge geometry leads to faster processing, improved surface quality and fewer rejects—advantages that directly affect throughput and quality assurance in production environments.
