Product Catalog

This is a revolutionary product which will save you time and money! These are 4" resin grinding cups. This 400 grit grinding cup should be used after the 200 grit if you are going all the way to a high gloss finish on your flat edges. Due to the continuous resin bonding used on this tool, this diamond cup wheel can be used on granite, engineered stone, marble, travertine, limestone or even onyx! If you have ever had problems getting smooth finishes when grinding brittle materials like marble then you will love this resin bonded diamond cup wheel!

This cup wheel requires you to use it with water as a coolant - do NOT run this unit dry! You can use it with a center feed water grinder or with a regular variable speed grinder set to low or medium speed with water on the face of the stone.

  • Step 4 to a high gloss flat edge
  • 5/8"-11 threaded arbor
  • Ultra Smooth finishes
  • 400 Grit

Try this product and you will not want to use metal bonded grinding cups again!
