Thickness Selection Guide

Thickness Best For
0.012" - 0.020" Soft to medium stone, fine trim cutting, minimal kerf
0.024" - 0.030" Medium-hard stone, standard lapidary trim saw work
0.036" - 0.048" Hard stone, large diameter slab cutting, maximum stability

Compatible Applications

  • Lapidary trim saw cutting - agate, jasper, quartz, obsidian, and all hard lapidary stone
  • Gemstone rough trimming - clean, precise cuts on valuable rough with minimal material loss
  • Stone slab cutting - 8" to 14" blades for slab saw work on larger stone pieces
  • Soft to medium stone cutting - thinner blades (0.012"-0.020") for minimal kerf on softer materials
  • Hard stone slab cutting - thicker blades (0.036"-0.048") for rigidity on hard stone
  • Most lapidary trim saws - 1/2" and 5/8" hole sizes for standard hobby and professional trim saws

Frequently Asked Questions

  • Q: What makes Red Thin Rim blades different from standard lapidary saw blades?
    A: Red Thin Rim blades use a sintered diamond rim construction - diamonds are distributed throughout the rim matrix and continuously exposed as the blade wears. This gives them longer service life than electroplated blades. The thin rim profile minimizes kerf width for cleaner cuts with less material loss.
  • Q: What size blade do I need for my lapidary trim saw?
    A: Match the blade diameter to your saw maximum blade capacity. Most hobby trim saws use 6" or 8" blades. Larger slab saws use 10", 12", or 14" blades. Always verify your saw maximum blade diameter and arbor hole size before ordering.
  • Q: How do I choose the right blade thickness?
    A: Use thinner blades for softer stones and fine trim work where minimizing kerf is important. Use thicker blades for harder stones and larger diameter cuts where blade rigidity and stability are more critical than kerf width.
  • Q: Should Red Thin Rim blades be used wet or dry?
    A: Always use wet. Run water or cutting oil over the blade continuously during cutting to cool the sintered rim, prevent heat damage to the stone, and extend blade life. Never run sintered diamond blades dry.
