10 Degree Pivoting Shaft (Swivel Shaft), High Speed Heavy Duty. Microstop Countersink Cage, WES598 Series

Precision Microstop Countersink Cages

Wescon USA’s precision microstops (countersink cages) are engineered to deliver absolute, repeatable depth control for critical airframe assembly.

Manufactured 100% in the USA using the highest quality aircraft-grade workmanship and materials, our microstops are built for high-cycle OEM and MRO environments. Capable of speeds up to 10,000 RPM, they feature dual ball bearings and heavy-duty thrust bearings to eliminate runout and vibration. With ultra-precise micro-adjustments in increments of 0.0005 inches, tooling engineers can dial in exact tolerances for any advanced composite or traditional alloy. To seamlessly integrate into global manufacturing lines, our entire catalog is available in both Imperial (e.g., 1/4-28) and Metric (e.g., M6x1, M8x1) cutter threads.

Interchangeable Foot Pieces for Surface Protection

Proper surface contact is vital during hole preparation. We offer multiple foot piece options tailored to your specific application. Choose non-marring Nylon or Phenolic or Steel foot pieces to protect delicate aircraft skins, cladding, and composite panels from scoring, in high-friction, heavy-duty production environments.

Custom Microstop Engineering

Beyond our extensive standard catalog, Wescon USA provides direct-to-manufacturer engineering solutions. If your assembly line requires extended reach cages, unique skirt geometries, vacuum-adapted tooling, or tight-clearance footprints, our engineering team can design and manufacture custom microstops tailored precisely to your airframe specifications.

• Micro-Adjustable Precision: Positive-locking 0.0005" increments guarantee exact countersink depths every time.
• High-Precision Spindles: Dual ball bearings and integrated dust seals eliminate chatter for mirror-finish hole preparation.
• Global Compatibility: Comprehensive availability in both metric and imperial cutter threads.
• Uncompromising Quality Control: Machined to stringent aerospace standards with bespoke tooling capabilities available directly from our production floor.
• In-House Production & Rapid Global Shipping: By managing the entire manufacturing cycle under one roof, we guarantee absolute quality control and offer lightning-fast shipping to aerospace facilities anywhere in the world.
