Description

Robert Charles Metric Piloted Countersink – 3 Flutes – Integral Pilot – Straight Shank is designed for precise countersinking of metric pre-drilled holes. The integrated pilot guides the cutter for accurate alignment and clean, concentric results with minimal chatter, while the three-flute geometry delivers smooth cutting and efficient chip evacuation across steels, aluminium, and plastics.

  • Integrated pilot for precise centering: Keeps the tool aligned with the pre-drilled hole, reducing wander and rework for repeatable, concentric countersinks across materials.
  • Three-flute design for smooth cutting: Delivers stable performance, efficient chip evacuation, and clean edge quality with minimal vibration.
  • Rigid straight shank with exact geometry (8.0 mm pilot, 100° angle): Ensures solid tool guidance in common holders and produces consistent countersink depth and angle across steels, aluminium, and plastics.

In daily use, this countersink streamlines your workflow by delivering repeatable, high-quality finishes with fewer passes and less noise or chatter. The integral pilot simplifies setup, keeps your hole alignment tight, and reduces the need for rework, while the robust construction supports long-term reliability in workshop, maintenance, and production environments. Whether you’re preparing precision fastener seats or finishing countersinks in a mix of materials, this tool provides dependable performance and consistently professional results.
