ZT680-S 10,000 RPM Rated Microstop Cage For Composite Material

Part Number: ZT680-S

The ZT680-S 10,000 RPM Rated Microstop Cage, originally designed for composite work, is the ultimate microstop cage on the market for contoured surface work! Full-bearing design and felt dust shield keeps composite dust out of the interior of the cage. Boeing and it's subcontractors have standardized on this microstop cage for all of the new B787 program. Here are a few of the features of this cage:


  • Fail-safe positive stop insures accurate repeatability and eliminates the possibility of work piece damage.
  • Felt dust shield eliminates composite/graphite dust contamination of the radial ball bearings extending cage life.
  • .0005″ incremental depth adjustment.
  • 3/4″ diameter cutter capacity with this “X” style footpiece. For information on other footpieces, please see the “microstop cages & cutters” section of our website.
  • 1/4″ shaft travel with either 1/4″-28 or 6mm internally threaded shafts.
  • Shaft style available in either in three flats, 1/4″ round or “quick-change” ball lock style.
