Looking like an overgrown keyhole cutter, you can use this cutter to cut a T-slot in a workbench or an assembly table. Once cut the T-slot enables you to use Axminster or Festool guide rail clamps as hold downs when working on a piece or gluing up. Alternatively a length of hardwood with a T-slot cut along its length can become a custom made or temporary guide rail. Alternatively, you can cut a T-Slot in nylon if making jigs to your own design. We suggest you remove the bulk of the waste with a straight cutter of the same diameter as the neck of the cutter (dimension E) prior to using the T-slot cutter.
