Abstract
A holder block is mounted on a carrier and has formed therein a first hole and a water passage. A sleeve is mounted in the first hole and receives a cutter bit. The sleeve includes a shank and an enlarged flange disposed at a front end thereof. The shank is disposed in the first hole. The flange includes a rearwardly facing shoulder bearing against an outer surface of the block. A second hole extends through the shank and the flange and is adapted to receive the cutter bit. A spray nozzle is disposed in the flange and is connected to the water passage by way of an annular groove, for receiving water which it sprays forwardly against the cutter bit.
