Diamond Pacific's Agate Slicer The Diamond Pacific Agate Slicer Lapidary Saw Blade has been designed to cut a variety of hard lapidary materials with minimal chipping. The stiffening/cooling slots guarantee straight cutting in dense rock material such as quartz, agates, geodes, petrified wood, and jaspers. This blade also does well with granite, marble, and porcelain tile. The cooling slots reduce the amount of heat and resistance generated when cutting, providing for faster cutting speeds, and a higher quality finish. These agate slicer blades are sturdy and durable and are popular with workshops and lapidary clubs as they can easily withstand abuse from beginners and high-volume scenarios. These blades should never be run dry under any circumstances. These blades will work with oil, but designed to run in water at 3200 to 3450 RPM. Blade bushings are available to adapt a chosen blade to your lapidary saw. Doesn't sound like the right blade for your needs?
