Abstract
PCT No. PCT/US79/00133 Sec. 371 Date Mar. 5, 1979 Sec. 102(e) Date Mar. 5, 1979, PCT Filed Mar. 5, 1979 PCT Pub. No. WO 80/01927 PCT Pub. Date Sept. 18, 1980 A router bit assembly (18,22) for the sides (20,24) of the bowl (10) of an earthmoving machine (12). The router bit assembly is of two-piece construction and includes a router bit (42) and a holder (26) which, when secured to the vertical side walls (20,24) of the bowl (10), captures the bit (42) between the holder (26) and the vertical side wall (24). The rear edge (56) of the bit (42) is held against the leading edge (58) of the corner (25) of the vertical side wall (24) by the holder (26). The two-piece router bit assembly advantageously reduces the amount of metal that is discarded when the life of the bit is expended.
