Description
The Robet Charles Imperial piloted countersink is a precision cutting tool designed to countersink holes with consistent depth and perfect alignment. It features a 3-flute cutting design, an integral pilot, and a 100° included angle to deliver smooth cutting and reliable starts in precision machining applications.
The countersink uses a 3/32" pilot diameter and is manufactured to tight tolerances, with the pilot diameter held to −0.0005" to −0.0015", delivering consistent, concentric results ideal for aerospace, automotive, and general engineering use.
- Integral pilot with 3/32" diameter: Guarantees precise hole alignment and repeatable countersinking for true starts and reduced rework.
- 3-flute design for smooth cutting: Efficient chip removal with minimal vibration, producing a cleaner finish and longer tool life.
- Tight pilot diameter tolerance: Pilot diameter held to −0.0005" to −0.0015", delivering consistently concentric countersinks for high-precision work.
By delivering precise alignment, smooth cutting, and repeatable tolerances, this tool helps you speed setup, reduce finishing steps, and achieve consistently high-quality countersinks. It supports demanding applications in aerospace, automotive, and general engineering, making it a trusted, reliable choice for professionals and hobbyists alike.
