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).for optimal results and extended saw blade sharpness use blade wax, mist lubricant system or air cooling, #512961, (D) diameter: 12 (300mm), teeth: 96, (D) bore: 1, tooth grind: TCG, hook angle: -6°, kerf (B): .126 (3.2mm), Plate (C): .102 (2.6mm), 512961 carbide Tipped aluminum and non-ferrous metals 12 inch dia X 96T TCG, -6 deg, 1 inch bore
