We install Cellflex 7/8 RFS cable at work, on a previous project we encountered a 1/8 inch thick steel plate that we had to cut to pull the cable through. It is difficult to cut this plate. A new place doing the exact type of installation came across the same type of steel plate and bought these cutters for the purpose. Sprayed some coolant on the surface and got started, within seconds the cutter did its job and I wondered why I didn't get it sooner Clean cut in seconds, blades look new Great tool!
