SPANISH DIFFERENCES WITH INSTALLATIONS AND USEFUL SKERPLATES

摘要

The cutter head of a rotary cutting head is formed with three pairs of recesses separated by a wall portion of the head. An abutment member is received in one recess of each pair, and a tool bit in the other recess in such a manner that a cutting edge of the bit projects from the cutter head. A threaded fastener engages the bit and the abutment member and clamps the bit to the wall portion, thereby releasably fastening the bit to the head.
