Title: Hole cutter for making circular openings in ceramic wall and floor tiles of clay
Inventor: RADZIWILL HEINZ
IPC: B23B51/05
Filed: 1981-09-10
Abstract: The making of openings in ceramic tiles of earthenware or clay or in existing tile coverings in old buildings, with a diameter of 60 mm for electrical connections and 40 mm for water and gas connections, is still a problem which the specialist (tile layer and fitter) solves more or less manually by traditional skilled handicraft methods. Large-sized tiles with an edge length of more than 300 mm impose especially high demands on the ability of the craftsman. For the non-specialist (do-it-yourself enthusiast), the problem cannot be solved, since suitable aids are not available. The hole cutter for which a patent has been applied, an attachment for every commercially available drilling machine, enables circular and semi-circular openings to be made at tile edges and tile corners without problem. The advantages:     a) considerably shorter working times,   b) a minimum of breakage   c) perfect cutting guidance. The hole cutter can be used both for individual tiles and for existing tile coverings. The cutter heads fitted in the cover sleeve in an accident-proof manner can be exchanged without difficulty in accordance with the particular diameter required of 60 mm, 50 mm and 40 mm. <IMAGE>
