Product Overview
SND840 Saw Grit Diamond is a synthetic diamond grit featuring a complete cube-octahedron crystal structure and medium toughness. It is developed for cost-effective, general-purpose diamond tool manufacturing where balanced wear resistance, consistent crystal characteristics, and practical production economics are important.
With its balanced combination of crystal morphology and mechanical toughness, SND840 is positioned for manufacturers producing diamond tools for construction, geological, and general industrial applications. It offers a practical grade option for applications that do not require the specialized performance characteristics of higher-end diamond grades.

Recommended Applications
SND840 is suitable for evaluating in diamond tool manufacturing applications where medium toughness and balanced wear characteristics are required.
- Diamond Saw Blades: General-purpose construction cutting tools and other applications where the selected diamond grade matches the workpiece and bond formulation.
- Diamond Core Bits: Drilling applications involving suitable rock and construction materials, including general geological sampling.
- Diamond Grinding Tools: General-purpose grinding applications where the crystal characteristics and bond system are appropriately matched.
- Industrial Diamond Tools: Cost-conscious tool manufacturing requiring a balanced combination of crystal structure and toughness.
Actual tool performance depends on grit size, diamond concentration, bond formulation, tool design, workpiece properties, and operating conditions. Application testing is recommended when selecting a new diamond grade.
Grade Selection: SND840 vs. Other Saw Grit Grades
SinoDiam offers multiple saw grit diamond grades to meet different tool manufacturing and application requirements. The following guide helps manufacturers identify the appropriate starting point for grade selection.
- SND830 – Economy Grade: Semi-blocky crystal morphology, positioned for cost-sensitive general-purpose diamond tools.
- SND840 – Medium Toughness Grade: Complete cube-octahedron crystal structure, offering a balanced option for general-purpose cutting and drilling tools.
- SND860 – Higher Toughness Grade: Blocky crystal morphology with medium-high toughness, designed for applications requiring greater crystal strength.
