Robet Charles Imperial Piloted Countersink - 3 Flutes Integral Pilot Straight Shank -3/32 Pilot Diameter - 100° Inclusive Angle - 3/16 Body Diameter

The Robert Charles Imperial Piloted Countersink – 3 Flute Integral Pilot Straight Shank is designed to deliver accurate countersinking for pre-drilled holes. Its integral pilot ensures precise alignment and chatter-free cutting, producing a clean, professional finish every time.

The 3-flute design provides smooth cutting action, enhanced stability, and efficient swarf evacuation, making it suitable for a range of materials including steel, aluminium, and plastics. Manufactured to high quality standards, this countersink is built for both workshop and production environments where precision and reliability matter.

• Integral Pilot for Precise Alignment: The precision-ground integral pilot keeps the countersink centered in the pre-drilled hole, reducing drift and delivering a clean, flush countersink with minimal chatter.
• Three-Flute Design for Smooth Cutting: The 3-flute geometry offers a smoother cutting action, greater stability, and efficient swarf evacuation for consistent results across steel, aluminium, and plastics.
• Defined Geometry with Robust Shank: Straight shank with a 100° inclusive angle, 3/16" body diameter, and 3/32" pilot diameter provide repeatable, reliable countersinks and compatibility with standard holders.

In use, this countersink helps you complete holes with professional precision, improving workflow and reducing rework. The integral pilot and 3-flute design work together to deliver reliable performance across common workshop materials, while the rigid straight shank and precise geometry support steady cutting and long tool life.
