Drag Knife - Tangential CNC Knife

The Donek Tools Drag Knife allows you to cut a wide array of things you would normally use a utility knife for, but with the precision of CNC. This D2 will fit onto a 1/2 inch spindle collet or router. The D4 will fit onto a 1/4 inch collet. It will cut a wide range of materials up to a depth of 1/4 inch. The blade orients itself similar to a wheel on an office chair during the motion of the CNC machine. The tip of the blade is slightly offset from the center of the collet so the knife will rotate according to the direction the CNC machine is moving. The Donek Drag Knife is designed to work best with inexpensive, standard utility knife blades. For the best and most consistent results, only bi-metal blades should be used.
