Description
Ductile Iron Diamond Blades feature a brazed diamond side coating that reduces binding and allows for grinding a beveled edge. Use for cutting through cast iron pipe, galvanized steel and non-ferrous metals such as bronze copper, chrome, zinc, and lead. They can even cut through high nickel-content material and stainless steel!
- The #1 choice of water departments and utility companies.
Limited Lifetime Warranty
All diamond tool products including blades, coring bits, hole saws and grinding wheels include a limited lifetime warranty against warping, cracking and material defects. If any diamond tool (being used for its intended purpose with at least 50% of the diamond life remaining) fails to cut or work properly, or if the bond between the diamond segment and the steel core becomes separated at any time, the tool may be replaced free of charge.
