Precisely designed to meet the requirements of the Incra Jig, these 8 Piece sets allow you to route tight-fitting dovetail and box joints with your table-mounted router equipped with an Incra Jig. Follow the directions in the Incra Jig manual and use the correct bit number for the joint you want to create. Both sets contain 2 Straight and 6 Dovetail bits, packed in an attractive wooden storage box. Use them to rout hardwood, softwood, plywood or composites. These bits also may be used with other router jigs.
