20 Inch Diamond Blades — Premium Cutting Performance

Yes. All DI Tool 20 inch diamond blades support both wet and dry operation. Wet cutting provides superior heat dissipation and extends blade life for prolonged sessions, while dry cutting offers jobsite convenience. For extended continuous cutting, wet operation is recommended to prevent overheating and maintain optimal segment performance.

Segment count varies by blade model. The All-Cut Supreme features 24 turbo segments, significantly more than the standard 16, for enhanced cutting capacity. The Heavy Duty Cured Concrete blade includes 42 segments for maximum milling capacity and extended blade life. More segments generally mean greater durability and cutting efficiency for hard materials.

Segment height depends on the model. The All-Cut Supreme offers 12mm segments with 15mm drop segments, while the Heavy Duty Cured Concrete blade features 10mm segments optimized for aggressive cutting of hard concrete. Taller segments typically provide longer usable blade life before the core is reached during repeated cutting operations.

DI Tool's 20 inch diamond blades use a 1"-20MM arbor, which is the standard for large-diameter saw equipment including walk-behind flat saws and ring saws. Always verify your saw's arbor specification before ordering to ensure compatibility. Adapter rings may be available for equipment with different arbor configurations.

DI Tool's 20 inch diamond blades are typically 0.125" to 0.142" thick depending on the model. For example, the Red Gullet blade in 20" is 0.125" thick, providing precise, clean cuts with minimal material loss. Thicker blades offer added stability and are better suited for aggressive cutting in harder or more abrasive materials.

Turbo segments feature a serrated profile that accelerates cutting speed and improves heat dissipation, making them ideal for hard concrete and masonry. U-slot (or gullet) segments use open gullets between segments to evacuate debris efficiently, offering versatile performance across softer aggregates, asphalt, and multi-material applications. The right choice depends on your primary cutting material.
