The Fill-in Set transforms Set 1 or 2 into a finely graded dovetail cutter collection. Now you'll always have the perfect cutter to match your wood thickness, even down to 8mm! Includes: WR-8-7-14.7, WR-8-7-20-10, WR-8-7-10-5 as well as the smallest WoodRat dovetail cutter, WR-8-7-8-4.

A specially chosen range of cutters for dovetailing, morticing and tenoning on the WoodRat WR900 or WR600. It's the perfect way to get started using a 1/2" router. This set also contains extra-long conversion sleeves for use with the supplied 8mm cutters and your own 1/4" cutters. Note: The WR-H-6-25-15 cutter cannot be used for making through dovetails on the WR600. It is, however, excellent for making sliding dovetails.
