Fabricators prefer to use DAMO Contour Blade and DAMO DWS-125 Stone Cutter to make a sink hole quickly and easily. Then follow by using DAMO Hand Profiler Z-Series to shape the edges. DAMO Hand Profiler Z-Series is also known as Zero Tolerance, Vertical Grinding Wheels or Drum Grinding. Adopting the latest “Vacuum Brazing Technology,” DAMO Hand Profiler Z-Series will maintain its original shape for a long time and deliver a very aggressive cutting performance.
