Robert Charles Metric Piloted Countersink - 3 Flutes - Integral Pilot - Straight Shank - 3.5mm Pilot Diameter - 90° Inclusive Angle

Robert Charles Metric Piloted Countersink – 3 Flutes – Integral Pilot – Straight Shank is designed for precise countersinking of metric pre-drilled holes. With an integral pilot for accurate alignment and a 3‑flute cutting geometry, it centers quickly and delivers clean, concentric chamfers with minimal chatter on steel, aluminium, and plastics.

• Integrated Pilot for Precise Alignment: The built‑in pilot centers the tool on the pre‑drilled hole, preventing wander and delivering true, concentric countersinks every time.
• Three‑Flute Design for Smooth Cutting: Three cutting edges provide a stable, efficient cut with reduced vibration and excellent chip evacuation across a range of materials.
• 90° Countersink Angle with 3.5 mm Pilot: Creates clean, uniform bevels for metric holes while the 3.5 mm pilot diameter keeps the tool guided and easy to use with a straight shank.

Whether you’re working in a high‑volume production environment, performing routine maintenance, or tackling precise hobbyist projects, this countersink helps you achieve professional chamfers quickly and consistently. The integrated pilot reduces setup time and wander, while the robust 3‑flute geometry delivers reliable performance across steels, aluminium, and plastics, providing repeatable finishes you can trust.
