Robert Charles Metric Piloted Countersink - 3 Flutes - Integral Pilot - Straight Shank - 12mm Pilot Diameter - 120° Inclusive Angle

The Robert Charles Metric Piloted Countersink – 3 Flutes – Integral Pilot – Straight Shank is engineered for precise, repeatable countersinking of metric pre-drilled holes. It’s an ideal choice for workshops, maintenance teams, and production environments where clean, accurate countersinks matter.

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, excellent stability, and efficient chip evacuation for dependable performance across a range of materials including steel, aluminium, and plastics.

• Integral Pilot for Accurate Alignment: Ensures the countersink starts true to the hole and minimizes wandering for first-pass accuracy.
• Three-Flute Cutting Geometry for Smooth Cutting: Delivers stable engagement, reduced vibration, and efficient chip evacuation for clean finishes across steel, aluminium, and plastics.
• 12 mm Pilot Diameter for Consistent Positioning: Provides repeatable entry and alignment with metric pre-drilled holes, enabling quick setup in high-volume tasks.

By delivering concentric countersinks with minimal chatter and reliable performance, this countersink helps you streamline machining workflows, reduce downtime, and achieve superior hole quality across a variety of materials. Its design supports faster setup, fewer reworks, and consistent results in workshop, maintenance, and production environments.
