Template bits also known as Pattern bits or Straight Bits with Centre Ball Bearing are used in woodworking to replicate letters, shapes or designs by means of copying an overlaid shape onto the desired material. The Ball Bearing guide will ride along the Template, and the carbide teeth will cut into the material at the exact diameter of the bearing, hereby “copying” the design flush with the bearing’s diameter.

Template Bits can be used in handheld and table-mounted routers. When used with a handheld router, the pattern is on top of the work; with a table-mounted router, the pattern is underneath the work.
