The Carbide cutting tip is brazed to a steel shank specially designed to cut grooves in composite building materials. Routing v-shaped grooves, whereby the aluminum cover and a part of the polyethylene core is removed, allows Folding/creasing the remaining material by hand. Special amana-grade carbide provides much longer tool life especially compared to carbide Tipped tooling. Composite material panels like TCM, ccm, and ACM are widely used for cladding many diverse exterior and interior applications such as office buildings, hospitals, convention centers, airports, and hotels. The long lasting durability of the material makes it an excellent choice for buildings, signage, displays, etc., #45745, diameter (D) 1/2, angle (a°) 90°, cutting height (B) 3/8, shank (D) 1/4, overall length (L) 2-1/8, B1 13/64, Type ZRN coated V-Groove, Max RPM 28, 000, flutes 2, D1 0.090", A1° 45, carbide V-Groove 90 deg.
