ABSTRACT:
The invention is directed to a cutting blade assembly (24) for a rotary cutter head (18) of a power planer tool (10). The blade assembly includes a pressure piece (36), and a blade carrier (60) which is mated with the pressure piece to define a blade slot (68) in which a cutting blade (70) is removably secured. The blade carrier (60) is fixed against movement relative to the pressure piece (36) by way of a dove-tail connection (46, 62) along the mating surfaces of the two pieces. The cutting blade (70) is fixed in elevation within the blade slot (68) by a projection (66) on the blade carrier (60) engaging a recess (72) on a side of the blade between its cutting edges.
