This Backout/Relief Cut Moulding 3-3/8" measures 3.375" wide, with a .062" depth of cut on the bottom horizontal moulding cutters. This universal profile can be utilized on many of our tongue and groove profiles like flooring, siding, and on the backside of crown mouldings to minimize cupping after the milling process.
The design layout is comprised of three shallow 1/4" radius plows, flanked by 15/32" wide fillets in the center, and a 47/64" wide fillet on each side edge of the pattern. The maximum width this backout knife can mill is 4-1/8" wide, that’s if the bottom moulder spindle is positioned at .000" axially.
