Robert Charles DIN 3 Flute Countersinks 120° - 8.3mm HeadDiameter

The Robert Charles DIN 3 Flute Countersinks 120° are precision tools designed to meet DIN standards for accurate 120-degree countersinking and chamfering. With a 3-flute geometry, they deliver smooth cutting, stable performance, and efficient chip evacuation for clean, consistent finishes. These countersinks are ideal for steel, aluminum, and plastics, making them a reliable choice for engineering, maintenance, and production environments where precision matters.

• Smooth cutting and burr-free finishes: Three-flute geometry minimizes cutting resistance and vibration, producing clean 120° countersinks and chamfers with minimal post-processing.
• Stable performance and efficient chip evacuation: DIN-compatible design and flute arrangement promote steady cutting under load while quickly clearing chips to reduce heat buildup and improve tool life.
• Wide material compatibility and reliability: Proven performance across steel, aluminium, and plastics, making it a versatile addition to any workshop or production line.

Used across engineering, maintenance, and production tasks, these countersinks help you achieve repeatable hole geometry, reduce rework, and maintain consistent quality between jobs. Their durable construction supports long tool life and dependable performance, so you can complete assemblies and prototypes with greater confidence and fewer interruptions.
