28.5 Degree Back Bevel Cutter

These 28.5-degree back bevel moulding knives are designed to mill a twenty-eight and one half-degree chamfer on the backside of a piece of crown, cove or bed moulding when milled sprung (laying horizontally flat) from on a right vertical cutter head. These knives create only half the determining factor of the final height and projection of these types of mouldings when installed. The other half of the equation for back cuts on these styles of mouldings will be a degree that combined equals ninety or slightly more, depending on the manufacturer's tolerances.

On this cutter layout the maximum depth of cut is .437", the maximum height of cut is fixed at .805". Every sprung moulding we design have height of cut numbers near the degree bevel on the layout papers we provide, that number must be smaller than the height number, in this equation .805" for this knife to be able to cut the entire back bevel while milling, if not, please select a larger size height bevel of the same degree. We purposely layout all our sprung mouldings with forty-five-degree back bevels and under to be milled on the right vertical cutter head, and all forty-five-degree back bevels and higher to be milled on the left vertical cutter head. This custom design practice will save thousands of dollars in manufacturing cost over the years, as well as moulder setup time.

For knife quoting purposes use the calculator below, we have added only the important measurements. A brief detailed explanation on how to use the calculator is located here. Need some assistance with the dimensions? Print a copy of our fraction - decimal - millimeter chart, place it on the moulder to help operators save time and increase accuracy during machine setup.

Thickness = 1.625" / Depth of Cut = .437" (right blades).
