Robert Charles Metric Piloted Countersink - 3 Flutes - Integral Pilot - Straight Shank - 10.0mm Pilot Diameter - 120° Inclusive Angle

The Robert Charles Metric Piloted Countersink – 3 Flutes – Integral Pilot – Straight Shank is engineered for precise and repeatable countersinking of metric pre-drilled holes. The integral pilot ensures accurate alignment and prevents tool wander, delivering clean, concentric results 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. Designed for reliability and consistent performance, this countersink is ideal for workshop, maintenance, and production machining applications.

• Integral Pilot for Accurate Alignment: The built‑in pilot guides the cutter as it enters the work, keeping the countersunk hole concentric and minimizing wander, which reduces rework and improves surface quality.
• Three-Flute Cutting Geometry: Three cutting edges deliver smooth, stable cuts with efficient chip evacuation, supporting consistent finishes across a variety of materials including steel, aluminum, and plastics.
• Straight Shank with 10.0 mm Pilot Diameter and 120° Included Angle: Enables quick setup in standard tooling and delivers a clean, flush 120° countersink across multiple materials, with precise guidance from the 10.0 mm pilot.

With dependable alignment, stable cutting, and easy integration into existing setups, this countersink helps you complete precision countersinking tasks more quickly and with repeatable accuracy. It reduces downtime, minimizes rework, and delivers professional-grade finishes—whether you’re updating a single part or running production lots in a shop, maintenance bay, or factory floor.
