ABSTRACT:
A cutter for removing chips from wood has a rotary carrier whose peripheral surface is formed with rearwardly and inwardly inclined recesses for permanent magnets which attract plate-like blades having cutting edges which extend radially outwardly beyond the peripheral surface of the carrier. The blades consist of magnetic material and are attracted to the permanent magnets. The magnets have dovetailed projections extending into complementary grooves of the carrier. Each blade is urged against the respective magnet by a spring-biased wedge in the respective recess, and the inner edge of each blade bears against a plate-like abutment which is attracted to the respective magnet.
