Robert Charles DIN 3 Flute Countersinks 60° are precision‑manufactured to DIN standards for accurate 60° countersinking and chamfering. With a 20.0 mm head diameter, these tools deliver clean, repeatable finishes on steel, aluminium, and plastics, making them suitable for engineering, machining shops, and production environments where precision matters.
- DIN-standard precision: Delivers repeatable 60° countersinks and consistent chamfer quality, helping parts seat flush and align features with minimal rework.

These countersinks help you streamline setup, speed assembly, and achieve precise finishes across demanding engineering and workshop tasks. Built to DIN standards and engineered for steady performance, they support consistent results in production runs and routine maintenance alike.
