Premium diamond continuous-rim cut-off disc for chip-free cuts on granite, marble, porcelain, ceramic tile, brick, and masonry. The ultra-thin constant-contact rim delivers up to 60% smoother cuts than standard diamond discs, with no burn marks on glazed or polished surfaces.

• 3" continuous-rim diamond disc, 20,400 RPM maximum operating speed
• Designed for use on a die grinder or 3" cut-off tool
• Hardened steel disc body absorbs vibration for precise high-speed cuts
• For granite, marble, porcelain, ceramic tile, brick, block, and general masonry
• Cuts dry or wet - run wet on extended cuts to extend disc life and reduce dust
• Fits standard die-grinder and cut-off tool arbors
• Diablo MPN DMADC0300

Tip: Let the disc do the cutting - apply light steady pressure and let the diamond rim abrade the material. Pressing hard glazes the diamonds and shortens disc life. For ceramic and porcelain tile, score 1/8" deep on the first pass then deepen on subsequent passes for the cleanest break edge.
