A wood moulder is a machine used to shape wood with profiled cutters. The profiled cutters are also known as knives, and blades. Tooling refers to cutters, knives, blades including planer blades, and cutterheads. Most moulders require the blades to be secured into a cutterhead that mounts on the shaft(s) of the machine. However, some machines such as the Williams & Hussey and the Shop Fox require the blades to bolt directly onto the shaft of the machine. The wood being fed into a moulder is commonly referred to as either “stock” or “blanks”.
