Bimetallic ring (crown) drills RUKO are used for work with hand drills and vertical drilling machines. When working on a vertical drilling machine, use only manual feeding. When processing easily cutting materials, the teeth provide a more even cut and allow less effort. Due to less vibration and the heat generation during cutting, the service life may increase by three times. They are used for non-alloy steel (strength up to 700 MPa), non-ferrous and light metals, plastics, gypsum, fibrous, plywood and wood.
