60 Degree Back Bevel Cutter - 3

This 60 degree back bevel moulding knife - 3 is designed to mill a sixty-degree chamfer on the left backside of a piece of lumber to produce crown, cove, or bed moulding. These knives create only half of the determining factor of the final height and projection when the moulding is installed, the other half of the mathematical equation is generally a degree (in this case thirty,) that combined equals ninety or slightly more. This 60-degree bevel has a maximum depth of cut of 1.125", the maximum height of cut is set at .650". Every crown moulding we design has height numbers near the side edge of the bevel, that number must be smaller than the height number, in this example, the number is .650" for this knife to cut the entire bevel while milling, if not, select a different bevel of the same degree.

We intentionally design all our crown mouldings with forty-five degree and under bevels milled on the right vertical moulder spindle, and all forty-five degree and higher cuts are milled on the left vertical spindle. This specialized practice will save thousands of dollars in manufacturing cost over the years. Please read our commentary about axial position for crown moulding, this article will help you dial this profile in axially on the first try when milling this detail on an industrial moulder, provided the machine is axially calibrated.

For knife quoting purposes use the calculator below, we have added only the important dimensions. A brief detailed explanation on how to use the calculator is located here.

Thickness = 1.625" / Depth of Cut = 1.125" (left knives).
