Robet Charles Imperial Piloted Countersink - 3 Flutes Integral Pilot Straight Shank -7/32 Pilot Diameter - 90° Inclusive Angle - 7/16 Body Diameter

The Robet Charles Imperial Piloted Countersink is a precision countersink tool designed for accurate countersinking of pre-drilled holes. It features a finely ground integral pilot that aligns with the hole, minimizing wander and delivering a clean, flush finish in steel, aluminium, and plastics.

Built with a 3-flute configuration and a straight shank, this countersink offers smooth cutting, improved stability, and efficient swarf evacuation. It uses a 7/32 in pilot diameter, a 90° included angle, and a 7/16 in body diameter, making it a reliable choice for repeatable results in both workshop and production settings.

• Integral pilot for precise alignment: The finely ground integral pilot ensures the countersink starts exactly where intended, reducing wandering and delivering a clean, flush finish.
• Three-flute design for smooth cutting: The 3-flute geometry provides steady cutting action, enhanced stability, and efficient swarf evacuation for materials like steel, aluminium, and plastics.
• Straight shank with defined dimensions: With a 7/32 in pilot diameter, 90° included angle, and 7/16 in body diameter, this tool offers repeatable results and easy compatibility with standard tool holders for quick, reliable setup.

By combining precise alignment, stable cutting, and easy integration into existing tooling setups, this countersink helps you achieve professional-quality holes faster. The integral pilot reduces misalignment, the 3-flute design maintains smooth performance under load, and the straight shank with standard dimensions simplifies tool changes to keep your workflow efficient and consistent across steel, aluminium, and plastics.
