Robert Charles Metric Piloted Countersink - 3 Flutes - Integral Pilot - Straight Shank - 6.0mm Pilot Diameter - 100° Inclusive Angle

The Robert Charles Metric Piloted Countersink – 3 Flutes – Integral Pilot – Straight Shank is a precision tool engineered for accurate countersinking of metric pre-drilled holes. The integral pilot guides the cutter with true alignment, helping prevent wander and delivering clean, concentric results with every cut.

Its 3-flute geometry provides smooth cutting, excellent stability, and efficient chip evacuation across a wide range of materials—including steels, aluminium, and plastics. With a straight shank and a 6.0 mm pilot diameter and 100° included angle, this countersink is ready for reliable use in workshop, maintenance, and production machining environments.

• Integral Pilot for True Alignment: The built‑in pilot ensures accurate alignment and prevents tool wander, delivering concentric countersinks even in deeper holes.
• Three-Flute Design for Smooth Cutting and Efficient Chip Evacuation: Balanced cutting geometry reduces chatter and promotes clean swarf removal for a superior finish on metal and non-metal materials.
• Metric Precision with Straight Shank: Designed for metric pre-drilled holes, the 6.0 mm pilot diameter and 100° included angle provide repeatable seating of fasteners, while the straight shank fits standard milling setups for reliable performance.

Designed for reliability and consistency, this countersink helps speed up setups, reduce rework, and deliver uniform flush or countersunk heads across parts. Its robust construction supports daily workshop or production use, making it a dependable choice for engineers, machinists, and maintenance teams seeking repeatable, high‑quality results.
