WM 86 Cove Moulding 1-5/8" - 1

This WM 86 Cove Moulding 1-5/8" - 1 measures 1.625" wide by .563" thickness. The common symmetrical design is comprised of a 7/8" radius cavetto in the center, attached to a 9/32" tall vertical fillet on top with a 9/32" wide horizontal fillet at the bottom. The spring angles are fixed at forty-five degrees, these specific back cuts set the installed height & projection at an identical dimension of 1-5/32" tall and wide.

Two high points in the design were intentionally positioned on the same plane, our disciplined design practices will assure excellent holddown conditions while milling the detail on an industrial moulder, providing the pressure shoe is parallel to the bed plates. Ever wonder why some mouldings look and feel better than others in the industry? Read our article on knife marks to learn how machine feed rates and rpm of the cutter head can directly affect the quality of your finished mouldings.

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

Width = 1.625" / Depth of Cut = .279" (top knives).

Thickness = .562" / Depth of Cut = .367" (right blades) & .367" (left cutters).

Grade of Steel

V2+RW

V2+RW Rockwell Hardness about 58-62, Good Quality. Made for short runs, (1' - 1000') of high quality millwork. This steel is flash coated with a special hard chrome coating (.001") thick to help provide very long wear on the cutting edge. It will outlast any standard M-2 steel that's not coated. This steel is easy to grind with standard grinding wheels and borazon finish wheels. This steel is easy to joint on high speed machines.

chrome coated 72rc face, best seller, great tool life

Black Nitride

BLACK NITRIDE Rockwell Hardness about 70-72 (Surface Only), Premium Quality. Black Nitride (carbon nitride) steel offers longer run times than standard M2 or M3 high speed steel (1' - 2000'). Adding pure carbon to the top surface of the knife steel hardens the cutting edge about .010" to obtain about a 72 Rockwell. Steel is black oxide to reduce pitch build up and rust, this also gives the steel a uniform color due to the case hardening. Because the steel is case hardened and higher on the Rockwell scale this steel is more brittle than other non-case hardened steels. Excellent for stubborn hardwoods and softwoods, but not recommended for knotty woods or very large cuts over 1" depth of cut.

black nitride case hardened 72rc, medium size runs

Endurance

ENDURANCE Rockwell Hardness about 70-72 (Surface Only), Superior Quality. Endurance super run is the premium of all high speed knife steels. They start with V2 base, then apply P.V.D. (Physical Vapor Deposits) in an Ion sputtering magnetron chamber. These deposits consist of a five layer film of Aluminum, Chromium, Molybdenum, Nitride, and Titanium. This forms an extremely hard and heat resistant cutting edge twice as hard as C2 grade carbide. Because the coating is so thin, normal vitrified rough wheels and CBN finish wheels can be used on this product. Special care must be taken not to hone the face of the tool with anything but a block of wood. Tool life is increased up to 600 percent over normal high speed steel. Small amounts of MDF (500' or Less) can be run with this product.
