DIN 335 C standard design 90° countersink angle for reliable seating HSS-Co for long tool life 5-piece set in durable plastic case

Precision seating and consistent hole finishing

The set is built to the DIN 335 C specification, providing a repeatable 90° countersink angle across the full 6.3–25 mm range. Manufactured from HSS‑Co, the tools offer a balance of toughness and wear resistance that reduces burr formation and minimises subsequent rework. The 3 cutting edges geometry ensures smooth material removal and a concentric finish, which helps maintain fast, reproducible results when chamfering drilled holes or preparing surfaces for fastener seating.

Faster throughput and lower maintenance effort

Thanks to the high‑alloy HSS‑Co composition and the three‑edge cutting design, the set delivers extended tool life and consistent cutting behaviour, which supports higher uptime in batch work. The set format simplifies tool changes and reduces downtime, while the included plastic case keeps cutters organised and protected between jobs. This combination of durability and practical storage supports leaner workflows and fewer interruptions on the shop floor.
