Schmidt Rail Backer — Profile 231IN

The profile 231IN backer is the profile-carrying element of the Schmidt multiprofile system: it seats in a multiprofile head or head blank and holds the matching profile 231IN carbide insert at the correct rake and radial position for the rail member of the profile 231IN stile-and-rail set. Because the profile lives in the backer-and-insert pair rather than in a dedicated cutter, a shop changes profiles by swapping backers on a head it already owns — no new arbor, no regrind. Pair this backer with the profile 231IN insert; order the opposing stile or rail member to complete the matching stile-and-rail set. Seats index to the head for repeatable setup across profile changes. Confirm head size and profile before ordering.
