Robert Charles Metric Piloted Countersink - 3 Flutes - Integral Pilot - Straight Shank - 5.0mm Pilot Diameter - 90° 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 centers the tool for accurate alignment and helps prevent tool wander, delivering clean, concentric countersinks with minimal chatter.

With a 5.0 mm pilot diameter and a 90° included angle, the 3-flute geometry provides smooth cutting action, solid stability, and efficient chip evacuation across a range of materials including steels, aluminium, and plastics. Built for reliability and consistent performance, this countersink is an ideal choice for workshop tasks, routine maintenance, and production machining applications.

• Integral Pilot for Precise Alignment: Built-in 5.0 mm pilot diameter centers the countersink in pre-drilled metric holes, preventing wander and delivering clean, concentric results with minimal chatter.
• Three-Flute Geometry for Smooth Cutting: The 3-flute design delivers steady cutting, excellent stability, and efficient chip evacuation for clean finishes across a variety of materials.
• Straight Shank for Easy Integration: Robust straight shank ensures reliable seating in standard toolholding and easy compatibility with common machines and setups in busy workshops.

By combining precise alignment, stable cutting performance, and durable construction, this countersink helps you achieve consistent depths and concentric finishes with fewer reworks. It streamlines setup, reduces downtime, and enhances overall workflow across workshop, maintenance, and production machining environments.
