Robet Charles Imperial Piloted Countersink - 3 Flutes Integral Pilot Straight Shank -1/8 Pilot Diameter - 90° Inclusive Angle - 3/8 Body Diameter

The Robet Charles Imperial Piloted Countersink is a precision countersinking tool designed for accurate, flush finishes on pre-drilled holes. It features a 1/8" integral pilot, a 90° included angle, and a 3/8" body diameter to ensure precise alignment and clean bevels across steel, aluminium, and plastics. The straight shank accepts standard chucks, making it suitable for both workshop use and production environments where repeatable results matter.

The 3-flute design delivers smooth cutting and efficient swarf evacuation, providing stable performance from first cut to finish.

• Integral 1/8"-diameter pilot for precise alignment: The built-in pilot centers each hole, delivering chatter-free countersinking and consistent depth for a professional finish.
• Three-flute design for smooth cutting and efficient swarf evacuation: The extra flute reduces chatter and speeds up material removal, giving a cleaner bevel on steel, aluminium, and plastics.
• Straight shank for quick setup and broad compatibility: Fits standard drill chucks and minimizes runout, ensuring reliable performance in both hand tools and CNC setups.

With its robust construction and precise grinding, this countersink helps you achieve repeatable bevels with fewer reworks, speeding up workflows and delivering consistent results across challenging materials. The integral pilot eliminates misalignment, while the 3-flute geometry reduces chip clogging and heat buildup for longer tool life. Whether you’re assembling cabinetry, fabricating metalwork, or finishing plastic components, you’ll enjoy reliable performance and a professional look from first cut to last.
