Common Crown Moulding 5" - 12

This Beautiful Crown Moulding 5" - 12 measures 5" wide by 3/4" thickness, the profile is one of the more common crown moulding styles, the pattern consist of a cyma recta flanked by vertical fillets with a cavetto joined to a horizontal fillet positioned on the bottom. When installed the height becomes 3-27/32" tall with a projection of 3-23/64" wide with the spring angles fixed at thirty-eight and fifty-two degrees. Three points of the crown design are positioned on the same level plane creating superior hold down conditions while milling the pattern on an industrial style moulder.

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.
