Robert Charles Metric Piloted Countersink - 3 Flutes - Integral Pilot - Straight Shank - 3.0mm Pilot Diameter - 120° Inclusive Angle

The Robert Charles Metric Piloted Countersink – 3 Flutes – Integral Pilot – Straight Shank is a precision tool designed to countersink metric holes with repeatable accuracy. Its integral pilot centers the cutter to prevent wander and delivers clean, concentric finishes across steel, aluminum, and plastics, making it ideal for workshop, maintenance, and production machining.

• Integral Pilot Alignment: Keeps the cutter centered in metric pre-drilled holes, reducing wander and delivering true, concentric countersinks.
• Three-Flute Cutting Geometry: Provides smooth, stable cutting and efficient chip evacuation for clean finishes and reduced cycle times.
• 3.0 mm Pilot Diameter with 120° Angle and Straight Shank: Fits standard toolholders, matches metric holes, and enables quick setup with consistent countersink depth across steels, aluminum, and plastics.

By combining precise alignment, smooth cutting, and reliable performance across common materials, this countersink helps you finish countersinking tasks faster with fewer rework cycles. The integrated pilot minimizes setup steps, while the straight shank ensures compatibility with a wide range of holders, improving changeovers in busy shops. Whether you’re prepping metal panels or plastic components, you’ll achieve repeatable depths, clean edges, and a professional finish that enhances overall productivity.
