The Robert Charles DIN 3 Flute Countersink 90° is a precision cutting tool designed to create clean, exact 90° countersinks and chamfers. Manufactured to DIN standards, it delivers consistent geometry and a smooth surface finish across multiple materials. The 12.4 mm head diameter provides a stable cutting profile for shallow to deeper countersinking tasks.

Ideal for engineering, maintenance, and production environments where precision and reliability matter. It works well on steels, aluminium, and plastics, enabling you to tackle a wide range of components with a single countersink.

DIN 90° countersink geometry: Precise 90° countersinks and chamfers with a consistent surface finish for repeatable results across jobs.
Three-flute cutting design: Smooth, stable cutting with reduced vibration and efficient chip evacuation for clean, accurate holes.
Wide material compatibility: Suitable for steels, aluminium, and plastics, enabling versatile use across projects and reducing tool changes.

The tool’s DIN-compliant geometry and three-flute design translate into reliable, repeatable performance, helping you achieve clean chamfers quickly and with minimal deburring. Built to withstand demanding workloads, it supports higher throughput in engineering, maintenance, and production environments while delivering consistent finishes across materials.
