Buying Guide
Key considerations when selecting diamond blades for stone include blade diameter and arbor compatibility, material compatibility, and cutting method. Large-diameter blades generally deliver faster cuts on hard stone but require appropriate equipment and safety measures. Continuous-rim blades provide clean cuts on ceramic tile and stone with reduced chipping, while segmented or turbo designs excel in faster stock removal for rough-cutting tasks.
Material quality, including diamond grit concentration and core durability, influences blade life and heat generation. For dry cutting, ensure ventilation and dust control; for wet cutting, provide water supply to maintain blade temperature and prolong life. Compatibility with your tool’s arbor size, RPM ratings, and maximum cutting depth should guide the final choice. Finally, consider whether you need a multi-pack, which can offer a cost-effective mix of blade geometries for various stone projects.
