Center Groover — 9/64″ × 1/4″, Deep-Profile C&P, Pro-Line (1-1/4″ Bore)

Cuts the 9/64″-wide, 1/4″-deep groove that seats a panel or glass edge in a stile-and-rail door frame — one of the narrowest widths Freeborn offers, sized for glass or thin stock. This is the center-groover option that substitutes for the standard tongue-and-groove cutter in Freeborn’s 1/2″ depth-of-pattern cope & pattern sets, the six-piece family that mills a deeper profile than the standard series. At 1/4″ depth — other than the standard 3/8″ — the tongue-and-groove option is not available and diameters differ, so you fence-adjust between cuts. The set is two matched cutters; profile cutters are not included. Pro-Line build: 3-wing, 1-1/4″ bore, 4″ diameter, counterclockwise, in carbide or T-Alloy. Drops straight into the 1/2″-depth cope & pattern stack for a consistent 9/64″ groove across the run.
