5″ x 4″ Insert Surfacing Head — 6-Wing, Straight Bore

The IN656 is the six-wing version of the 5 in. surfacing head with a 4 in. cutting length, adding cutting edges for a finer finish and higher feed capability on mid-size moulders and planers. The aircraft-aluminum body runs light, quiet, and on less horsepower than a steel head. Six wings hold four-sided solid carbide inserts in a staggered spiral pattern that shears the grain cleanly, with 24 effective cutting teeth — more edges in the cut than the four-wing IN653, so each edge takes a smaller bite and leaves a smoother, often line-free face. Inserts rotate to a fresh edge or replace on the machine, with no grinding required. The constant cutting diameter keeps setup minimal between indexes, and the light cutting pressure lets feed speeds run higher. Specify bore size when ordering.
