Type DF

One of the most popular types of grinding stones. A special corundum with a medium soft bond is used as an abrasive for these stones, which guarantees high shape stability. Therefore, it is still possible to well correct the contours of the grinding stone surface to the desired shapes. A special area of ​​application is in the machining of cutting and pressing tools and in the creation of molds, where very good results are achieved. This stone can be used for all types of steel for the production of molds and also for pre-processing of aluminum or copper with the addition of beryllium. The stone can be used by hand, in sawing attachments or ultrasonic heads (for high-performance ultrasounds, use caution, as thinner stones may crack under load due to a medium soft bond). When working with these stones, we recommend using the oil to work with abrasive stones grinding stones with dirt and increases the grinding performance and quality of the treated surface.
