The Lenox Tools 10833800RDG Diamond Grit Reciprocating Saw Blade 8-Inch - 1 Pack is specifically designed for cutting Cast iron. This blade will eliminate the need for using a snap cutter, making the job of removing cast iron pipe easier and safer. The Nickel alloy-brazed particles maintain sharpness to keep cutting after conventional carbide grit fails allowing you to cut more pipe without changing blades. This blade also has a narrow kerf which allows you to make thinner and faster cuts. Unlike Bulky snap cutters which crush the pipe and leaves ragged, uneven cuts, this blade leaves a nice clean cut.
