Description
The Robet Charles Imperial piloted countersink is engineered for precise, repeatable countersinking in precision machining. Designed for professionals across aerospace, automotive, and general engineering, it delivers accurate seating for fasteners with minimal runout. Its integral pilot and straight shank help ensure clean, concentric countersinks from first pass to last.
- Integral 5/32" Pilot Diameter + Straight Shank: Built-in pilot with a straight shank ensures precise hole alignment and effortless mounting in standard tool holders for quick setup and dependable performance.
- 3-Flute Design for Smooth Cutting: The three-flute geometry provides efficient material removal with reduced chatter, yielding a clean, uniform countersink finish even in tougher materials.
- 82° Included Angle with Tight Pilot Tolerance: An 82° seating angle delivers reliable fastener flushness, while the pilot diameter is held to −0.0005" to −0.0015", ensuring repeatable, concentric results across production runs.
Together, these features empower you to achieve consistent countersinks with minimal rework, faster cycle times, and reliable results batch after batch. The tool's precise pilot and robust geometry help maintain alignment and finish quality, making it a trusted choice for demanding applications in aerospace, automotive, and engineering shops alike.
