Diamond Notched Saw Blades

Diamond Notched Rim Saw Blades – Coarse-Cut Blades for Lapidary Slabbing & Stone Cutting

Professional diamond notched rim saw blades for lapidary slabbing, coarse stone cutting, and high-volume material removal. The notched rim design creates segments that improve coolant flow, reduce heat buildup, and allow faster cutting speeds than continuous rim blades — ideal for harder materials and larger diameter cutting applications. Available in 100mm to 610mm (4" to 24") diameters with kerf from 0.15mm to 2mm. Sold in 5-pack and 10-pack sets. From $30.00.

Frequently Asked Questions

  • Q: What is the advantage of notched rim diamond blades over continuous rim blades?
    A: Notched rim blades have segments separated by gullets (notches) that channel coolant across the blade face and evacuate stone particles during cutting. This allows faster cutting speeds, better heat management, and longer blade life on hard materials compared to continuous rim blades. The trade-off is a coarser cut edge with more chipping — continuous rim blades produce smoother, cleaner cuts but cut more slowly.
  • Q: Why are these blades sold in 5-pack and 10-pack sets?
    A: Multi-pack sets provide better value for high-volume lapidary operations and production cutting environments where blades are consumed regularly. The 10-pack sets (smaller diameters) and 5-pack sets (larger diameters) are priced to offer significant savings over individual blade purchases, making them ideal for lapidary clubs, production shops, and serious hobbyists who cut frequently.
  • Q: What kerf thickness should I choose for slab sawing?
    A: For slab sawing, kerf selection depends on blade diameter and material hardness. Smaller diameter blades (100–150mm) can use thinner kerfs (0.15–0.30mm) due to their shorter blade span. Larger diameter blades (12"+) require thicker kerfs (0.024"+) for adequate blade rigidity and stability during cutting. Always use the thinnest kerf that provides stable cutting for your specific saw and material combination.
  • Q: Do notched rim blades require water cooling?
    A: Yes — water cooling is essential for all diamond saw blade applications. The notched rim design improves coolant distribution across the blade face, but adequate water flow must still be maintained throughout cutting. Running notched rim blades dry will rapidly destroy the diamond segments and can cause dangerous blade failure. Always ensure your saw's water system is functioning before cutting.
  • Q: What is the maximum cutting depth for these blades?
    A: Maximum cutting depth is approximately 1/3 of the blade diameter (the usable rim depth). For example, a 6" blade provides approximately 2" of cutting depth; a 12" blade provides approximately 4" of cutting depth. For thicker slabs, use a larger diameter blade or make multiple passes from opposite sides of the material.
