This Backout/Relief Cut Moulding 3" - 7 measures 3.000" wide, with a .125" depth of cut on the bottom horizontal moulding cutters. This profile can be utilized on hundreds of our thicker sized casings and chair rail mouldings.
The functional profile is comprised of a 1-1/2" wide by 1/8" deep plow flanked by forty-five degree bevels, they both transition into 3/4" wide straight fillets on each side edge of the detail. The maximum width these cutters can mill is 3-3/4" wide, when the bottom horizontal moulder spindle is positioned at .000" axially.
Our purple colored ceramic blend grinding wheel, hogging at 2000 rpm, at a twenty-five degree back clearance angle, will rough grind a set of high-speed steel moulding knives in a minimal amount of time.
