Specifications

Pro-Tip: To prevent the diamond segments from glazing over, avoid using excessive downward pressure. Let the diamonds do the work. If you notice a drop in cutting speed, briefly drill into a softer abrasive material like a cinder block or a specialized dressing stone to expose fresh diamonds on the segment face, restoring the bit's original cutting speed.
