Coarse Grinder

Our GR20 is a high-speed, heavy-duty, wet or dry grinder engineered to quickly accomplish your coarse grinding stage. It can be used to prepare large or small samples for metallographic or spectrographic purposes.

  • 3 HP (2 kW) motor drives a balanced 12-inch (30 cm) diameter aluminum wheel at 1750 RPM (60 Hz)
  • An efficient dust collecting system draws the dust-laden air out through an expansion chamber, then through fiberglass filters to remove remaining particles
  • The water inlet, located inside the base of the splash bowl, connects to the water outlet in the protective wheel guard to promote better abrasive flushing
  • Available single or double 36-inch (90 cm) console models feature laminated phenolic working surfaces and include 6-inch (15 cm) cup sinks with stainless water spouts
