Window Sash Cutter Set (4-Piece) — Profile 020, Pro-Line (1-1/4″ Bore)

A complete four-piece cutter set for machining traditional wood window sash — the matched rail-and-stile members that frame the glass in double-hung windows, divided-light frames, and glazed cabinet doors, on stock up to 1-3/4″. The sash profile is carried by Freeborn’s profile-020 reference rather than a shape name; see the product image for the machined cross-section. It runs counter-clockwise with the stock fed face down. Pro-Line: 1-1/4″ bore, 4″ outside diameter, three wings, carbide or T-Alloy. The Mini-Pro counterpart is MC-67-020.
