The Turbine Wheel® brand diamond wheel has a unique, sawtoothed profile. As the crests wear, sharp fresh diamond is exposed, making it one of the fastest roughing wheels ever built for preforming agate, jasper, and other hard stones. The 1" arbor hole is bushed to 3/4", 5/8", and 1/2". Recommended operating speed is 1500 to 2000 rpm.
