Diablo's Diamond Metal Cut-Off Discs deliver extreme durability, minimal downtime and increased productivity. These diamond rimmed discs deliver up to 100X longer cutting life versus a standard bonded cut-off disc in some of the most intense metal cutting situations. The disc's long-lasting durability maximizes cutting even in extreme applications such as rebar, angle iron, cast iron and steel bar. Diablo's diamond metal cut-off discs not only provide long lasting cutting life, durability and control, but they also allow for a safer cutting experience.
