Diamond Coarse Cut Notched Blades

Diamond Coarse Cut Notched Blades - Heavy-Duty Notched Rim Blades for Stone and Glass

Diamond Coarse Cut Notched Blades are heavy-duty lapidary saw blades designed for aggressive, fast cutting through stone, glass, and ceramic. The notched rim design with thicker blade bodies (0.3mm-1.2mm) provides the rigidity and cutting aggression needed for hard stone slab work, rough stone trimming, and large-diameter cutting applications. Available in 4" through 12" diameters with multiple hole sizes to suit a wide range of lapidary trim saws and slab saws.

Compatible Applications

  • Hard stone slab cutting - aggressive notched rim for fast cutting through granite, hard minerals, and dense stone
  • Rough stone trimming - rapid material removal on lapidary rough before fine trim saw work
  • Large-diameter slab cutting - 8" to 12" blades for slab saw work on large stone pieces
  • Glass cutting - notched rim for controlled cutting on thick glass and glass blocks
  • Ceramic and tile cutting - heavy-duty cutting on dense ceramic and porcelain
  • Production cutting - thicker blade bodies for rigidity and stability in high-volume cutting

Frequently Asked Questions

  • Q: When should I use a coarse cut notched blade vs. a thin slicer blade?
    A: Use coarse cut notched blades for rough stone trimming, hard stone slab cutting, and applications where cutting speed is more important than kerf width. Use thin slicer blades for precious stones, fine trim work, and applications where minimizing material loss is the priority. Coarse cut blades are more forgiving of aggressive feed rates and harder materials.
  • Q: What hole size do I need for my saw?
    A: Most hobby lapidary trim saws use a 5/8" arbor. Larger slab saws typically use 3/4", 20mm, or 25mm arbors. Check your saw arbor diameter before ordering. Reducing bushings are available if your blade hole is larger than your saw arbor.
  • Q: Should these blades be used wet or dry?
    A: Always use wet. Run water or cutting oil over the blade continuously during cutting to cool the diamond rim, prevent heat damage, and extend blade life.
