Matching diamond tool specifications to material hardness, abrasiveness, and equipment type is essential for productivity and finish quality. This selection guide covers blades, core bits, and grinding wheels for the most common natural and engineered stones.
Material Hardness and Abrasiveness
Dekton and porcelain are extremely hard and dense, requiring blades with high diamond concentration and hard bonds. Granite varies from 6-7 on the Mohs scale; harder varieties need blades with premium diamond quality. Marble is softer but more abrasive, favoring blades with softer bonds that release diamonds at a controlled rate.
Blade Selection by Material
- Dekton and sintered stone: vacuum brazed or laser welded turbo blades, 12-14 mm segment height
- Granite: laser welded segmented blades for bridge saws, electroplated blades for handheld angle grinders
- Marble and limestone: sintered blades with copper or bronze bond for clean edges
- Porcelain tile: continuous rim electroplated blades or fine-grit vacuum brazed blades
Core Drill Bit and Grinding Wheel Matching
For drilling, match core bit bond hardness to material: copper bond for granite and porcelain, steel bond for marble. Grinding wheels should follow the same principle—electroplated for aggressive stock removal on concrete, vacuum brazed for long-life grinding on granite and quartz.
Equipment Considerations
Bridge saws and masonry saws benefit from larger diameter laser welded blades with cooling slots. Handheld grinders require smaller diameter blades rated for the grinder RPM. Always verify arbor compatibility and use proper flange support.
Consult manufacturer cutting data and conduct test cuts on representative material samples before committing to large production runs.
