The Robert Charles Metric Piloted Countersink is a precision tool designed to countersink metric pre-drilled holes with repeatable accuracy.
Designed for reliability and consistent performance, it features an integral pilot for exact alignment, a 3-flute cutting geometry for smooth cutting and efficient chip evacuation, and a straight shank for rigidity. With a 10.0 mm pilot diameter and a 100° included angle, it delivers clean, concentric countersinks across steels, aluminium, and plastics—making it suitable for both workshop and production machining tasks.
- Integral pilot for accurate alignment: The integrated guide prevents tool wander and ensures concentric countersinks with repeatable results.
- 3-flute design for smooth cutting and efficient chip evacuation: Provides stable cutting performance and effective chip clearance across a range of materials, reducing chatter.
- Straight shank with precise pilot diameter and angle: 10.0 mm pilot diameter and 100° included angle offer rigid setup and consistent depth control for reliable countersinking in steels, aluminium, and plastics.
This countersink helps you complete projects faster with clean, concentric countersinks, reduces rework from misaligned holes, and delivers consistent finishes across steels, aluminium, and plastics in workshop, maintenance, and production environments.
