The Carbide cutting tip is brazed to a steel shank specially designed to cut grooves in composite building materials. These bits are widely used as cladding for many diverse applications such as office buildings, hospitals, convention centers, airports, hotels. Routing v-shaped grooves, whereby the steel cover and a part of the polyethylene core is removed, allows Folding/creasing the remaining material by hand., #45778, diameter (D) 1/2, angle (a°) 90°, cutting height (B) 3/8, shank (D) 1/2, overall length (L) 2-3/8, B1 13/64, Type Altin coated V-Groove, Max RPM 28, 000, flutes 2, D1 0.090", A1° 45°, RPM 18, 000 - 24, 000, carbide V-Groove 90 deg.
