Robert Charles Metric Piloted Countersink - 3 Flutes - Integral Pilot - Straight Shank - 6.0mm Pilot Diameter - 90° Inclusive Angle

The Robert Charles Metric Piloted Countersink is engineered for precise, repeatable countersinking of metric pre-drilled holes. It’s a reliable choice for engineers, machinists, and workshop users who need clean, concentric results from every hole every time.

The integral pilot features accurate alignment to prevent tool wander, delivering clean countersinks with minimal chatter. Its 3-flute cutting geometry provides smooth cutting performance, excellent stability, and efficient chip evacuation, making it suitable for a wide range of materials including steels, aluminium, and plastics. Built for reliability and consistent performance, this countersink is ideal for workshop, maintenance, and production machining applications.

• Integral Pilot for Precise Alignment: Centers the countersink with the pre-drilled hole, prevents wander, and delivers consistently concentric countersinks with minimal chatter?
• 3-Flute Geometry for Smooth Cutting and Chip Evacuation: Balances cutting forces for stable, clean cuts and efficient debris removal, helping extend tool life across metals and plastics.
• Metric 90° Countersink with 6.0 mm Pilot Diameter and Straight Shank: Designed for metric applications, compatible with standard straight-shank tooling, and optimized to produce accurate countersinks quickly and reliably.

With this countersink, you gain faster setup, repeatable results, and reduced rework across production runs or routine maintenance. It enhances workflow by delivering dependable performance on steels, aluminium, and plastics, ensuring high-quality edge preparation and consistent results from the first part to the last.
