Diamond Blades for Cutting Rocks

For cutting rocks, a diamond blade with a segmented or turbo segment design is recommended. Segmented blades like the Red Gullet Diamond Blade excel on hard natural stone and granite, while turbo blades provide faster cutting with smoother finishes. For tile and polished stone, a continuous rim blade delivers chip-free results.

Natural stone such as granite, marble, and fieldstone is best cut with a laser-welded diamond blade. The J-Slot Premium Diamond Blade and All-Surface Supreme Premium Diamond Blade are ideal for tile-sized stone pieces, while the Red Gullet and All-Cut Supreme Diamond Blades handle larger, harder natural stone and masonry cutting applications.

DI Tool offers diamond blades for rock cutting in diameters ranging from 4 inches up to 24 inches. Smaller blades (4"–10") suit tile and countertop stone work, medium blades (12"–16") handle general masonry and stone cutting, and large-diameter blades (18"–24") are suited for heavy-duty construction and road-grade rock cutting.

Most DI Tool diamond blades — including the Red Gullet and All-Cut Supreme — support both wet and dry cutting. Wet cutting extends blade life and reduces dust, while dry cutting offers convenience in field conditions. The All-Surface Supreme Premium Diamond Blade is wet-use only to protect its double-reinforced core during tile and stone operations.

Match the blade's bond hardness to the hardness of the material. Harder stones like granite require a softer bond for better diamond exposure, while softer stones use a harder bond. Segment design matters too — segmented blades offer aggressive cutting, turbo blades balance speed and finish, and continuous rim blades deliver chip-free cuts on polished stone.

DI Tool diamond blades are compatible with a wide range of equipment including angle grinders, handheld circular saws, walk-behind saws, table or masonry saws, and tile saws. Each product specifies compatible arbor sizes (typically 5/8", 1"-20MM, or 20MM), so always verify the blade's arbor matches your saw before use.
