Robert Charles Metric Piloted Countersink - 3 Flutes - Integral Pilot - Straight Shank - 6.0mm Pilot Diameter - 120° Inclusive Angle

The Robert Charles Metric Piloted Countersink is a precision tool designed to countersink metric pre-drilled holes with repeatable accuracy. It features an integral 6.0 mm pilot that centers the cutter in the hole, preventing wander and delivering clean, concentric results.

With a 120° included angle and three-flute geometry, this countersink delivers smooth cutting, strong stability, and efficient chip evacuation across a range of materials, including steels, aluminum, and plastics. The straight shank ensures compatibility with standard chucks and holders, making it a reliable choice for daily use in workshops, maintenance bays, and production environments.

• Integral 6.0 mm Pilot: Ensures precise alignment and prevents tool wander, delivering clean, concentric countersinks every time.
• 3-Flute Cutting Geometry: Provides smooth cutting, high stability, and efficient chip evacuation for consistent finishes on metals and plastics.
• 120° Included Angle with Straight Shank: Standard chamfer geometry and broad holder compatibility for reliable performance in production and maintenance workflows.

In practice, this countersink helps you achieve accurate countersinks in a single pass, reduces chatter, and speeds up setup. Its versatility across steel, aluminum, and plastics supports a streamlined tooling inventory, improves workflow efficiency, and delivers repeatable, high-quality results in both small-batch and production machining tasks.
