4 in. Insert Stile Head, 3-Wing, 1-1/4 in. Bore, Shaker Pattern — Groove

Cuts the groove along shaker cabinet door stiles and rails — the 4 in. groove body in Schmidt’s insert shaker set, the smaller-diameter option. Three wings on a 1-1/4 in. bore run counter-clockwise with the wood face down, seating 30mm carbide ISR70 groove inserts (ISR70SC, or ISR70SCEE for an eased edge) — the same inserts used by the 4-1/2 in. ISRH700S. The groove receives the tongue from the matching ISRH70R rail head and captures the floating center panel. Sold as the body only; inserts ordered separately. Also available as the 4-1/2 in. ISRH700S.
