Thanks to its special carbide formulation and blade geometry, this is the ideal blade for cutting relatively thick-walled aluminum and non-ferrous metal bars such as copper, brass, bronze and Lead. It also is good for cutting extrusions and profiles. 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), #512721-30, (D) diameter: 12 (300mm), teeth: 72, (D) bore: 30mm, tooth grind: TCG, hook angle: -6°, kerf (B): .126 (3.2mm), pinholes: 2/7/42, 2/9/46 & 2/10/60, plate (C): .102 (2.6mm), 512721-30 carbide Tipped aluminum and non-ferrous metals 12 inch dia X 72T TCG, -6 deg, 30mm bore
