LENOX® Double Tang DIAMOND™ Reciprocating Saw Blade with a narrow kerf design for thinner, faster cuts. The cutting edge features nickel alloy brazed diamond particles that help to maintain sharpness, so it keeps on cutting long after conventional carbide grit fails. Fitted with a durable chrome alloy backing steel that provides extra stability. LENOX® DIAMOND™ Blades cut cleanly through cast iron, tile, granite and other abrasives, unlike bulky snap cutters which crush pipes and leave ragged, uneven cuts.
