Geared templates are designed to fit a specific tool, for example, Peter Wolters, Speedfam or Strasbaugh, among others. These tools have specific geometries that dictate the diameter and gear tooth design of the template.
Geared templates typically come in two formats, pin drive and gear drive. Pin drive templates have teeth with rounded slots and are driven by pins on the polishing tool. Gear drive have a more conventional gear appearance.
Single side, double side and double single side templates are all available. The double single side template has pockets for the work pieces to be mounted back-to-back.
