Festool's Domino series of mortising machines are each designed to work with their own size range of tenons. With the Domino DF 500 being designed for 4mm to 10mm tenons in smaller stock, and the Domino XL DF 700 designed for 8mm to 14mm tenons in larger stock.
Our 5mm cutters for the Domino XL DF 700 allow cutting mortises to work with tenons 5mm in size, up to 50mm deep.
To make these cutters, we start with genuine Festool DF700 cutters and have them precision ground and sharpened to 5mm using an 8 axis CNC cutter grinding machine. We have found them to be rather durable and cut well, however, It's important to note that care should always be used not to plunge the cutter into the work surface too quickly or damage to the cutter and/or workpiece can occur.
These 5mm cutters with their extended 50mm cutting depth are perfect for through tenons. However, for cutting 4mm/5mm/6mm/8mm/10mm standard depth mortises with the Domino XL DF700, a more economical and versatile solution is our RTS-500 Domino Cutter Adapter.
