Designed for shaping aluminum composite (sandwich) materials (ACM) with 90ª angle v-grooves with Flat bottoms. 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. Ideal for wall panel fabrication., ACM is 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., #45792, diameter (D) 1/2, angle (a°) 90°, cutting Height (B) 3/8, shank (D) 1/4, overall length (L) 2, B1 13/64, Type carbide Tipped V-Groove, Max RPM 35, 000, flutes 2, D1 0.090", A1° 45°, carbide Tipped double edge Folding V-Groove 90 deg X 0.090 inch tip width x 1/2 dia x 3/8 x 1/4 inch Shank
