By vigorously drilling into the sharpening stone, new chip spaces are created between the diamond grains, which ensure good cutting ability. If no cutting ability is achieved by sharpening, the dressing stone BO 5000498 should be used beforehand.
This version of the sharpening stone is especially suitable for larger drill diameters, diamond segment drills, and particularly for high-performance automatic drills such as Benteler with automatic sharpening device.
