Robert Charles DIN 3 Flute Countersinks 60° - 16.0mm HeadDiameter

Designed to DIN specifications, the Robert Charles DIN 3 Flute Countersinks 60° deliver precise 60-degree countersinking and chamfering for metal, plastic, and composite parts. It’s built for engineers, machinists, workshop teams, and production environments where consistent, high-quality finishes matter.

With a 16.0 mm head diameter, this countersink provides a stable platform for deeper countersinks and uniform seating. The three-flute geometry enables smooth cutting and efficient chip evacuation, helping to maintain sharp edges and reduce heat buildup. Compatible with a wide range of materials, including steel, aluminum, and plastics, it’s a reliable choice for everyday use in busy shops.

• DIN-compliant 60° countersink geometry: Ensures accurate 60° countersinking and chamfering to DIN standards, giving consistent fits and a professional finish across parts.
• Three-flute design for smooth cutting and chip evacuation: Delivers stable cutting action, reduces vibration and heat, and produces clean, uniform results even on tougher materials.
• Durable, versatile construction with 16.0 mm head diameter: Sturdy construction resists wear in demanding shop environments; the 16.0 mm head diameter provides rigidity and consistent depth across steel, aluminum, and plastics.

By delivering consistent depth, clean chamfers, and reliable repeatability, this countersink helps you speed up setups, reduce rework, and improve overall part quality. It pairs with other DIN-standard tooling in professional shops and is suitable for both production runs and precise DIY projects where precision matters.
