Robert Charles Piloted Microstop Countersink - 3 Flute - Integral Pilot - Threaded Shank - 1/8 Pilot Diameter - 100°

The Robert Charles Piloted Microstop Countersink is a precision tool designed for engineers, machinists, and precision shops. It features a 3-flute cutting design and an integral pilot, delivering accurate hole alignment and consistent countersinking for demanding aerospace, automotive, and precision engineering applications.

Designed for use with microstop cages and equipped with a threaded shank, this countersink provides secure fitment and reliable depth control across multiple setups. The pilot diameter is held to tight tolerances, ensuring each countersink starts true and finishes precisely where you need it.

• Precise 3‑Flute Countersink with 100° Angle: Delivers efficient material removal and a clean, flush countersink with every pass, producing smooth finishes and dependable tool life on challenging materials.
• Integral Pilot for True Alignment: Built‑in pilot centers each hole before countersinking, reducing wandering and delivering repeatable accuracy across parts and batches.
• Threaded Shank with Microstop Cage Compatibility and Tight Pilot Tolerances: Securely locks into your machine for reliable depth control; pilot diameter held to −0.0005" to −0.0015" to ensure high‑precision starting holes and consistent depths.

This combination supports consistent, high‑quality results in critical applications, helping you reduce setup time, minimize rework, and achieve repeatable countersinks across complex assemblies. Trustworthy performance from aerospace to precision automotive components translates to faster workflows, better part quality, and greater overall productivity.
