Robet Charles Imperial Piloted Countersink - 3 Flutes Integral Pilot Straight Shank -1/4 Pilot Diameter - 90° Inclusive Angle - 1/2 Body Diameter

The Robet Charles Imperial Piloted Countersink is a precision 3-flute countersink with an integral pilot and straight shank, designed for accurate, chatter-free countersinking of pre-drilled holes. With a 1/4-inch pilot diameter, 90° included angle, and a 1/2-inch body diameter, it delivers clean, repeatable countersinks across steel, aluminum, and plastics.

• Integral Pilot for Precise Alignment: The built-in pilot centers the cutter with the hole, reducing wandering and delivering a flush, professional countersink every time.
• Three-Flute Design for Smooth Cutting: Three cutting edges provide steady, efficient material removal and better swarf evacuation, helping maintain edge quality on multiple materials.
• Rigid Straight Shank for Easy Integration: Fits standard drill chucks and holders with minimal runout, offering consistent performance in both manual and production environments.

This combination of alignment accuracy, smooth cutting action, and tooling rigidity translates to faster setup, fewer reworks, and consistently professional finishes on every project—whether you’re in a busy workshop or running production. It’s a dependable addition to any toolkit that demands reliability and repeatable results.
