10'X80T NON-FERROUS GRINDThanks 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.
