Glass Groover — 9/64″ × 1/4″, Rubber Extrusion, Pro-Line (1-1/4″ Bore)

Cuts the 9/64″ wide, 1/4″ deep groove that seats a glass pane held by a rubber extrusion (glazing spline) in a Freeborn cope & pattern door frame. It takes the place of the standard tongue-and-groove groover in the set when the panel is glass rather than solid wood. Catalog note: “Glass option (for rubber extrusion).” Profile cutters are not included — this is the groover only. Pro-Line build: 3-wing, 1-1/4″ bore, 4″ diameter, counterclockwise, in carbide or T-Alloy. Choose it when the door takes a rubber-glazed glass panel instead of a wood one.
