8″/64T NON FERROUS T.C.G.GRIND 586401 Carbide Tipped Aluminum and Non-Ferrous Metals 8 Inch Dia x 64T TCG, -6 Deg, 5/8 Bore #586401 Specification (D) Diameter 8 (200mm) Teeth 64 (d) Bore 5/8 Tooth Grind TCG Hook Angle -6° Kerf (B) .110 (2.8mm) Plate (C) .087 (2.2mm) Thanks to its special carbide formulation and blade geometry, this is the ideal blade for cutting relatively thin-walled aluminum and non-ferrous extrusions and frames. The negative hook angle (-6°), triple-chip grind and thick plate combine to produce a superior finish. The blade can also be used to cut other “difficult” materials such as plastic, PVC tubing, fiberglass and ACM (Aluminum Composite Material). Warning: Never attempt to cut ferrous metals with these blades. Clamp down the workpiece. For optimal results and extended saw blade sharpness use blade wax, mist lubricant system or air cooling.
