The DXE0130 DiamondX® Cutter is an all-new thin diamond blade that replaces .040/45 thin abrasives. DiamondX® Cutter will cut virtually any metal including steel and stainless steel. Unlike abrasives, use the DiamondX Cutter edge to safely deburr flashing. For optimum results on steel and stainless steel; use on sheet and section material up to 3/8" thick or use on solids, bar, and bolts up to 3/4" thick. The diamond thin cut-off wheels are ideal for dry cutting of metal, rebar, iron, brass profiles, aluminum, different types of pipes, and sheet metal. Its solid steel wheel body significantly reduces the risk of shatter and injury for added safety. The diamond cutting edge of these cut-off wheels is 100% contaminant-free and will not wear down. They are easy-to-cut workpieces made of metal, stone, and stainless steel.
