PL (Product Liability) In accordance with the PL (Product Liablility) law, we have attached a WARNING label on the 5. METALCUTTING SAFETY case of METOMET products. There isno warning on the surface of the tools. Please read this safety guidelines before using carbide tools and provide safety education to all users. DANGEROUS FACTOR SAFETY COUNTERPLAN 2. Basic characteristics of CEMENTED CARBIDE toolsCemented carbide tools are made of carbides , nitrides, carbonitrides, oxides of W, Ti, Al, Si, Ta, Betc and metal component like CO, Ni, Cr, Mo as binder.
