3-Pc Set Double Edge Folding V-Groove Router Bits for Aluminum Composite Material (ACM) Designed for shaping Aluminum Composite (sandwich) Materials (ACM) with flat bottom V-grooves. 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. Designed for cutting and scoring aluminum sandwich materials including: Acetate Aluminum, Brass, Bronze, Clay, Zinc & Wood Composite Panels Aluminum Composite Materials (ACM) Aluminum Composite Panel (ACP)* ALPOLIC® Copper Composite Material (CCM) Alucobond® Alupanel® Bakelite Dibond® Durabond** e-panel™ Etalbond® Nylon Phenolics Plastic/Acrylic Plexiglas® PVC Thermoplastics Titanium Composite Material (TCM) Wood *Aluminum Composite Panel (ACP) is a type of ACM flat panel that consists of two thin aluminum sheets bonded to a non-aluminum core. ACPs are frequently used for external cladding or facades of buildings, insulation, and signage. **Durabond is a polyethylene core with 0.3mm colored aluminum sheet on either side, pre-finished requiring no decoration.
