Frequently Asked Questions

• Q: Which diamond blade is best for cutting agate and jasper on a lapidary trim saw?
  A: Sintered diamond trim saw blades (4"–6") are the best choice for agate and jasper — the sintered bond self-sharpens as it cuts, providing consistent performance through hard, abrasive material. Thin-rim blades minimize kerf loss when cutting valuable rough.
• Q: What is the difference between a slab saw blade and a trim saw blade?
  A: Slab saw blades (8"–18") are designed for cutting large rough stone into slabs on a slab saw machine. Trim saw blades (4"–6") are used on smaller trim saws to shape slabs into workable pieces for cabbing or faceting.
• Q: Can I use a continuous rim blade for cutting gemstones?
  A: Continuous rim (Pro Slicer) blades are ideal for chip-free cutting of glass, tile, and softer gemstones. For hard lapidary materials like agate, jasper, or quartz, sintered or thin-rim blades are more durable and efficient.
• Q: How do I choose the right blade diameter for my lapidary saw?
  A: Match the blade diameter to your saw’s maximum capacity. Common sizes: 4"–6" for trim saws, 8"–14" for mid-size slab saws, and 16"–18" for large production slab saws. Always check your machine’s arbor size and use an arbor adapter if needed.
• Q: Do I need water cooling when using diamond saw blades?
  A: Yes — all diamond saw blades require water or oil coolant to prevent overheating, extend blade life, and reduce dust. Running a blade dry will rapidly destroy the diamond bond and void any warranty.
• Q: What are diamond band saw blades used for in lapidary?
  A: Diamond band saw blades allow continuous cutting of stone and hard minerals with minimal kerf loss. They are ideal for cutting irregular shapes and curved profiles that circular blades cannot achieve.
