Robert Charles DIN 3 Flute Countersink 90° - 11.5mm Head Diameter

The Robert Charles DIN 3 Flute Countersink 90° is a precision cutting tool designed to create exact 90° countersinks and chamfers in a wide range of materials. Engineered to DIN standards, it delivers clean, uniform finishes and reliable performance in engineering, maintenance, and production environments. The 11.5 mm head diameter provides a stable cutting profile for consistent results across parts.

• DIN-standard precision for consistent results: The 90° countersink follows DIN specifications to deliver precise chamfers and uniform surface finish, reducing rework and ensuring parts fit first time.
• Three-flute design for smoother cutting and better chip evacuation: The 3-flute geometry minimizes vibrations, improves stability, and helps clear chips quickly for cleaner holes and longer tool life.
• Wide material compatibility with durable, shop-floor-ready construction: Effective on steels, aluminium, and plastics, with a robust build designed to withstand daily use in engineering, maintenance, and production settings.

This countersink helps you streamline your milling or drilling workflow by delivering accurate, repeatable chamfers with a high-quality surface finish. Its stable cutting action minimizes tool deflection and downtime, while broad material compatibility expands its usefulness across mixed-material assemblies. With reliable performance and a precise 90° angle, you can expect consistent results that improve part quality, reduce rework, and help your team meet tight production schedules.
