Robet Charles Imperial Piloted Countersink - 3 Flutes Integral Pilot Straight Shank -3/32 Pilot Diameter - 120° Inclusive Angle - 1/4 Body Diameter

The Robet Charles Imperial Piloted Countersink is a precision tool designed to create accurate, clean countersinks in pre-drilled holes. With an integral 3/32" pilot and a 120° inclusive angle, it aligns perfectly with your bore to deliver a consistent chamfer every time. The 1/4" body diameter and straight shank provide stiffness and compatibility with standard countersink holders, making it suitable for both small workshops and production environments.

This countersink is engineered for reliability across common materials—steel, aluminium, and plastics—delivering chatter-free cutting, smooth surfaces, and minimal rework. Its precision-ground geometry and robust construction are built to withstand frequent use in busy shops while maintaining repeatable results.

• Integral Pilot for Precise Alignment: The built-in 3/32" pilot guides the cutter, ensuring exact alignment with the pre-drilled hole and reducing chatter for a clean, repeatable countersink.
• Three-Flute Design for Smooth Cutting and Efficient Swarf Evacuation: The 3-flute geometry delivers steady cutting action, improved stability, and fast removal of chips across steel, aluminium, and plastics, minimizing clogging and deflection.
• Rigid Straight Shank with 1/4" Body Diameter: A straight shank fits standard tool holders, while the 1/4" body diameter provides rigidity and consistent seating, supporting uniform results even in tougher materials, with a 120° inclusive angle for a reliable chamfer.

This combination of precision pilot, stable 3-flute cutting, and robust construction translates to faster setups, fewer passes, and consistently flush countersinks across a range of materials. It helps you reduce rework, improve edge quality, and maintain high production output without sacrificing accuracy or reliability.
