Do not attempt to increase wear life by hard surface welding on cutting edges. This can result in premature failure.
After removing cutting edges, or router bits, clean all mounting surfaces before installing new edges or bits, or rotating used ones. See chart for BOLT TORQUES FOR CUTTING EDGES when mounting cutting edges or router bits.Cutting Edges
With two edges to each section, double wear can be obtained by rotating each edge. Remove bolts. Rotate edge 180°. Install bolts. By exchanging sides, the end section can be used four times to extend life. Remove bolts, install edges on opposite sides. Install bolts.Cutting Edge Teeth
