Description
The Robert Charles Piloted Microstop Countersink – Removable Pilot – Threaded Shank is a precision countersinking tool designed for highly accurate depth control and repeatable finishes. Its removable pilot and threaded shank provide quick size changes without losing alignment, while the secure connection to compatible microstop cages ensures stability during every cut. This makes it a dependable choice for aerospace, engineering, and precision assembly applications.
Designed for versatility, this countersink features a 3/32" pilot diameter and a 2 mm pilot shank diameter with a 100° countersink angle. It delivers clean, uniform countersinks across a variety of materials, maintaining tight tolerances over long runs and reducing the need for rework.
- Removable Pilot for Quick Size Changes: Swap pilots in seconds to accommodate different hole sizes without re-aligning the setup, minimizing downtime and keeping production moving smoothly.
- Threaded Shank for Secure, Repeatable Cage Fit: The threaded interface locks firmly into microstop cages for stable alignment and consistent depth control across multiple parts.
- 100° Countersink with Precision Geometry: Delivers clean, flush finishes with smooth edges and reduced chipping on metals and composites alike, even in demanding applications.
With its removable pilot, secure threaded connection, and precise 100° profile, this countersink enhances workflow efficiency, reduces set-up and rework time, and delivers reliable, repeatable results across high-volume production and precision assemblies. Trustworthy construction and compatible design give you confidence to tackle tight tolerances and complex parts with each job.
