Window Sash Cutter Set — 7-Piece S-Alloy Insert (Glass) with 3/8″ Sticking, 7″ × 1-1/4″ Bore (3-Wing)

The insert-tooling version of the WC231 seven-piece window sash cutter set — S-Alloy replaceable knives rather than brazed tips, configured with a 3/8″ sticking width, 7″ diameter, 1-1/4″ bore, three wings. Insert tooling lets a shop index or replace worn knives at the machine rather than sending the head out for sharpening. Supplied by special order. See WC231 for the brazed-tip version; the 3/8″ sticking configuration matches the WC231 pairing.
