Description
The Robert Charles Piloted Microstop Countersink is a precision tool designed for accurate countersinking in aerospace, automotive, and precision engineering. With a 90° countersink angle, a 14 mm cutter diameter, and a 3/16" pilot diameter, it is built to partner with microstop cages for repeatable depth control and exact hole alignment.
- Integral Pilot for Accurate Alignment: The built‑in pilot ensures holes are aligned precisely, delivering consistent countersinks and concentric results with minimal setup.
- Threaded Shank for Secure Fitment and Depth Control: The threaded connection locks firmly in your holder or tool holder, providing dependable depth control and reduced drift during operation.
- Tight Tolerance Pilot Diameter: Pilot diameter held to −0.0005" to −0.0015" delivers exceptional alignment accuracy, making it ideal for high‑precision work in demanding environments.
By delivering precise alignment and consistent countersink depth, this tool streamlines your workflow, reduces setup time, and yields clean, flush countersinks that meet tight specifications batch after batch. Designed for durability and reliable performance in demanding environments, it helps you improve part quality and overall productivity.
