Wastewater is tough on grinders. Gritty material wears the cutters and acidic conditions corrode them. Previously, operators needed to choose hard steel alloy cutters and sacrifice corrosion resistance. Or choose softer corrosion-resistant stainless steel cutters and sacrifice abrasion resistance. Now you do not have to choose. JWC Monster Metal® is a hard, corrosion-resistant alloy. Monster Metal is a trade secret alloy with the right balance of carbon for strength and chromium for corrosion resistance. The result is Monster Metal increases the usable life of your grinder cutters. Plus there is an extended 5-year warranty on the Muffin Monster® and 3-year warranty on the Channel Monster® and Channel Monster® FLEX*.
