The HMT VersaDrive Rebar Cutter is designed for applications where concrete has steel plate or rebar reinforced areas.
SDS & masonry drills will not effectively create holes through metal. The triple cut Carbidemax teeth are specifically designed for effective cutting of metal.
When a hole is found to contain steel or reinforcement, withdraw the SDS drill and cut through the steel with the rebar cutter, then continue with the SDS drilling.
