The Robet Charles Imperial Piloted Countersink is a precision 3-flute countersink with an integral pilot and straight shank, designed for accurate countersinking of pre-drilled holes in steel, aluminum, and plastics. Its precision-ground integral pilot ensures perfect alignment and chatter-free starts, delivering a clean, professional finish with every cut. The 3-flute design provides smooth cutting, improved stability, and efficient swarf evacuation, making it a dependable choice for both workshop and production environments where precision matters.

• Integral 1/8" pilot for precise alignment: The precision-ground pilot centers the countersink in the drilled hole, delivering accurate starts and a consistently clean chamfer with every cut.
• 3-flute design with 120° inclusive angle: Allows fast, smooth cutting and reliable swarf evacuation across steel, aluminum, and plastics, reducing chatter and tool deflection.
• 1/4" body diameter with straight shank: Provides rigid seating in standard holders and machines, supporting stable depth control and long, consistent performance across jobs.

Whether you're assembling parts in a shop or completing production runs, this countersink helps you achieve repeatable results quickly. The combination of an integral pilot, robust cutting geometry, and a straight shank means fewer reworks, reduced downtime, and a professional bevel that enhances fit and appearance for every project.
