TECWERK Taper Countersink Set DIN 335 C — HSS, 90° (6.3–25 mm), 5‑piece

The TECWERK taper countersink set DIN 335 C is a compact cutting tool range for accurate chamfering and deburring of drilled holes in workshop and production settings.

• DIN 335 C standard for consistent geometry
• 3‑flute high-speed steel construction
• 90° countersink angle for chamfering and deburring
• Supplied in robust plastic case

Consistent hole finishing that reduces rework

The set follows the DIN 335 C specification to ensure repeatable geometry across operations, which translates into consistent chamfering and reduced manual rework. Built from HSS, the cutters combine toughness with good heat resistance under typical drilling and countersinking speeds, helping to maintain edge sharpness during batch work. The defined 90° angle provides a standard bevel for countersinks and screw seats, simplifying assembly tolerances and inspection.

Cutting geometry engineered for efficient material removal

A 3‑flute design balances chip evacuation and cutting stability to produce a smooth edge with fewer burrs. The five cutters cover a broad diameter spectrum (6.3–25 mm) so a single set accommodates common hole sizes encountered in repair, maintenance and small-scale production. This range reduces tool changes and stock complexity while offering suitable flexibility for varying component designs. The geometry supports steady feed rates and predictable results on through‑holes and spot finishes.

Durable construction and organised storage for the workshop

The cutters are supplied in a plastic case that protects ground cutting edges during transport and keeps the set organised at the workstation. The solid‑body HSS construction provides a robust core material that withstands typical workshop use and occasional higher loads without chipping easily. The case design aids inventory control and reduces risk of accidental damage, helping to extend usable tool life and lower replacement frequency.

Practical advantages for procurement and maintenance planning

Selecting a standards‑based tool set streamlines quality assurance and simplifies supplier comparisons for procurement teams; the adherence to DIN 335 C offers a clear technical specification for documentation and incoming inspection. With a compact range in one kit, maintenance crews and small production facilities can reduce tool variants on the shelf while maintaining readiness for common countersinking tasks. Where additional specification or application details are required, technical documentation and sample testing remain straightforward thanks to the standardised geometry.
