Robert Charles DIN 3 Flute Countersink 90° - 8.3mm Head Diameter

The Robert Charles DIN 3 Flute Countersink 90° is a precision cutting tool designed to create true 90-degree countersinks and clean chamfers. Manufactured to DIN standards, it delivers consistent geometry and a superior surface finish with an 8.3 mm head diameter for robust performance.

With a 3-flute design, this countersink provides smooth, stable cutting with reduced vibration and improved chip evacuation. It is suitable for a wide range of materials—steel, aluminium, and plastics—making it a versatile choice for engineering, maintenance, and production environments where reliability and precision matter.

• DIN-standard precision: Engineered to exact DIN specifications, giving consistent countersink diameter and angle and easy integration with standard drill setups for repeatable results.
• Three-flute design for smooth cutting: The 3-flute geometry reduces cutting forces and vibration, delivering a cleaner finish and reliable chip evacuation for fewer clog-ups during longer runs.
• Material versatility and durable edge: Effective on steels, aluminium, and plastics, with robust edge geometry that resists wear, helping you complete more work without frequent tool changes.

Using this countersink, you can expect consistent depth and clean flush finishes across diverse materials, reducing rework and boosting throughput. The DIN-standard accuracy, combined with the stable 3-flute cutting action, translates to quicker setup, fewer tool changes, and improved surface quality—all contributing to a smoother workflow, higher first-pass results, and greater confidence in every machining task.
