Frequently Asked Questions

  • Q: What makes REZ resin soft wheels different from standard sintered wheels?
    A: REZ wheels use a foam-backed flexible resin bond that provides a softer, more conforming grinding action compared to rigid sintered metal bond wheels. This produces smoother surface finishes, reduces chipping on delicate gem materials, and extends the grit range all the way to 50000 for pre-polish work - eliminating the need to switch to separate polishing pads for many lapidary applications.
  • Q: What are the 4 and 6 grit wheels used for?
    A: The ultra-coarse 4 and 6 grit REZ wheels are designed for rapid stock removal on very hard gem rough - removing large amounts of material quickly before progressing to finer grits for shaping and pre-polish. These are specialty wheels for aggressive initial shaping on hard materials like corundum, topaz, and dense quartz.
  • Q: Should REZ resin soft wheels be used wet?
    A: Yes - always use with water cooling. Water prevents overheating of the resin bond, extends wheel life, reduces stone dust, and produces cleaner grinding results on all lapidary gem materials.
