New & innovative, RZR Cermet tipped circular saw blades cut faster and 2X longer than standard carbide tipped blades Cermet = a ceramic and metal compound that resists heat and friction Razor sharp cermet teeth, specifically engineered to cut steel resist and dissipate heat for cool, smooth, bur-free cuts. Ideal for cutting steel plate, angle iron, pipe, all thread and more Special tooth geometry and hardened steel body increase tool life. Super thin kerf design reduces cutting resistance for faster cutting.Unique laser slits reduce vibration/noise for stable cutting. Max thickness of cut= 1". Please note that when cutting pipe or tubing, "max thickness of cut" refers to wall thickness, not overall diam.
