137mm OD x 305mm CB Knife Head, 4-Pocket, 22° Hook, 1-13/16 in. Bore

Runs corrugated-back knives across a full 305mm (12″) working length — the longest head in Schmidt’s 137mm (5-3/8″) diameter straight-bore series, for wide moulding and paneling profiles that a shorter head can’t span in one setup. Four knife pockets with 22° hook double the cuts per revolution of the 2-pocket version for better finish at production feed rates, taking standard 16-60° corrugated-back knife stock in 1/4″, 5/16″, 3/8″ or 10mm thickness — the same CB knife inventory as the shorter 50mm-230mm heads in the series. For the two-pocket head at this length, see MH46302; for shorter lengths in the series, see the MH461-464 range. Confirm bore and machine spindle before ordering.
