Sintered Diamond Grinding Wheels – Heavy-Duty Lapidary Grinding

Professional sintered diamond grinding wheels for heavy-duty lapidary grinding of hard and abrasive stone. Sintered (metal bond) construction embeds diamond throughout the wheel body — delivering maximum durability, consistent cutting performance, and long wheel life on quartzite, granite, basalt, and highly abrasive gemstone materials.

Frequently Asked Questions

  • Q: When should I use sintered wheels instead of standard metal bond wheels?
    A: Sintered wheels are the best choice for very hard or highly abrasive materials (quartzite, basalt, granite) where standard metal bond wheels wear too quickly. The sintered bond continuously exposes fresh diamond as the wheel wears.
  • Q: Are sintered grinding wheels the same as sintered saw blades?
    A: Both use sintered (metal bond) diamond construction, but grinding wheels are designed for surface grinding on a cab machine arbor, while sintered blades are for cutting on a saw. They are not interchangeable.
  • Q: Do sintered wheels require water cooling?
    A: Yes — wet grinding with water coolant is required to prevent overheating and extend wheel life. Sintered wheels are more heat-tolerant than resin bond wheels but still benefit significantly from coolant.
