Cope & Pattern Split Groover Set — 3/8″ Depth, Standard C&P, Eased Edge, Mini-Pro (3/4″ Bore)

Cuts the center groove that closes a stile-and-rail door frame, sized to run inside the Eased Edge version of Freeborn’s 10 and 50 series cope & pattern sets. The four-piece split design carries shims between the cutters, so one set adjusts the groove anywhere from 3/16″ up to just under 3/8″ instead of a separate groover per width — and the split also lets you dial out spindle-alignment error a fixed groover would drive straight into the joint. This set runs a 3/8″ groove depth — Freeborn’s standard depth — so it keeps the tongue-and-groove option available on the set. Profile cutters are not included; the set substitutes for the standard tongue-and-groove groover in a cope & pattern set you already run. Mini-Pro build: 3-wing, 3/4″ bore, 2-15/16″ diameter, counterclockwise. Hold a consistent 3/8″ center groove across a production run without re-shimming between parts.
