CMT blade designers and technicians present the new Non-Ferrous Metal Saw Blade with the high quality performance you expect from CMT. Key features include high impact strength teeth made from special formulation carbide, a triple chip tooth configuration for longevity and a close tooth-to-body ratio - 0.122 tooth to 0.098 blade plate - gives better support to the tooth. The -7° hook angle provides controlled cutting for a smooth finish, without collapsing channel or storm window frames. Special gullet design allows for efficient chip evacuation. The CMT Non-Ferrous Metal blade is ideal for miter, radial and table saws and gives an optimum performance cutting aluminum, brass and other non-ferrous metals. NOTE: We highly recommend using a liquid lubricant. Wax stick for lubrication NOT RECOMMENDED.
