Robet Charles Imperial Piloted Countersink - 3 Flutes Integral Pilot Straight Shank - 3/32 Pilot Diameter - 82° Inclusive Angle

The Robet Charles Imperial Piloted Countersink is a precision cutting tool engineered for repeatable countersinking in metalworking and precision engineering. Its 3-flute cutter and integral pilot guide the tool for concentric, clean countersinks, making it a reliable choice for aerospace, automotive, and general engineering work. The 3/32 inch pilot diameter provides accurate alignment with your existing drill sizes, ensuring a consistent start every time.

With a tight pilot diameter tolerance of -0.0005" to -0.0015" and an 82° included angle, you get consistent seating depth and a smooth finish across materials. The result is repeatable, concentric countersinks that minimize rework and maximize productivity in demanding manufacturing environments.

• Integral pilot for precise alignment: Built-in pilot guides the cutter for concentric countersinks and repeatable starts, reducing drift and ensuring true hole alignment on every job.
• 3‑Flute design for smooth cutting: Three cutting edges remove material efficiently while minimizing vibration, delivering a clean finish even in tougher metals.
• Tight pilot diameter tolerance with 82° included angle: Pilot diameter held to -0.0005" to -0.0015" for consistent, concentric results, with the 82° angle providing reliable seating across a range of applications.

This countersink is designed to improve workflow by delivering predictable results, reducing setup time, and minimizing rework. Its precise tolerances and robust geometry help you achieve professional, consistent seating across aerospace, automotive, and general engineering projects, boosting overall productivity and part quality.
