Abstract: A planer-type face milling machine for processing wood having a drive motor that is coupled to a work spindle, which supports, on a free end, a milling head, which on its front side supports cutting edges, the milling head being configured particularly as a disk-shaped body, running parallel to the workpiece surface, the milling cutting edges being supported by a cutter, particularly a planar one, furnished with main and secondary cutting edges, and removably arranged on the milling head, is configured as a particularly effective and-tool machine in that the planer-type face milling machine is correspondingly small and light and has a housing having a handle, the milling head supporting a cutter without a main cutting edge and having only at least one secondary cutting edge.

Abstract: A cutter blade (17) for a finger joint cutter head (10) which includes a cantilevered cutting tip attachment. A cantilever pocket (20) is formed in the fillet area of steel backing member (18) to receive and hold the inner end of a hard material cutting tip (19), such as tungsten carbide. Cantilever pocket (20) has tapered sides which diverge outwardly and a rounded vertex or pocket bottom. Cutter tips are elongated to extend well into cantilever pockets (20). Each cutter tip is attached within a pocket (20) and along the joint surface of steel backing members (18), using a sandwich braze, to form braze joints (21) and (22).
