Blade Type Selection Guide

Blade Type Best For Cut Quality Speed
Pro Slicer Ultra-Thin Precious gem rough, minimal material loss Excellent — very clean edge Moderate
Red Thin Rim Sintered General lapidary trim saw work, clean cuts Very good Good
Coarse Cut Notched Fast slab cutting, rough rock, large material Good — rougher edge Fast
Continuous Rim Tile, glass, smooth edge cuts Excellent — chip-free Moderate
Frame Saw Blades Jade, amber, sapphire — frame saw machines Very good Slow/precise

Frequently Asked Questions

  • Q: Which blade type should I choose for cutting gemstone rough?
    A: For precious gem rough where minimizing material loss is critical, use Pro Slicer ultra-thin blades (0.004"–0.016" kerf) — the thinner kerf means less gem material lost to sawdust. For general lapidary trim saw work, Red Thin Rim sintered blades offer a good balance of cut quality and blade life. For fast rough slab cutting where speed matters more than edge finish, use Coarse Cut notched blades.
  • Q: What is the difference between sintered and electroplated diamond saw blades?
    A: Sintered blades (Red Thin Rim, Premium Sintered) have diamonds embedded throughout the metal segment — as the segment wears, fresh diamonds are exposed, giving much longer blade life. Electroplated blades (Pro Slicer) have a single diamond layer on the surface — they wear faster but can be made much thinner for ultra-low kerf precision cutting. Choose sintered for longevity; choose electroplated for minimum kerf.
  • Q: What arbor size do I need for my saw?
    A: Most lapidary trim saws use 5/8" arbors. Some smaller trim saws and tile saws use 1/2" arbors. Check your machine's spindle specification before ordering. Most blades in our range are available in both 1/2" and 5/8" arbor options.
  • Q: Do diamond saw blades require water cooling?
    A: Yes — always use water cooling with diamond saw blades. Water prevents overheating of the diamond segment bond, extends blade life significantly, reduces stone dust, and produces cleaner cut edges. Never run diamond saw blades dry.
  • Q: What size blade do I need for a slab saw vs a trim saw?
    A: Trim saws typically use 4"–10" blades for cutting smaller stones and trimming rough. Slab saws use larger blades (10"–24") for cutting large rough rock into slabs. Match the blade diameter to your machine's maximum blade size specification.
