KOMET USA's ZR Polishers have been specially developed to meet the preliminary and final polishing requirements of zirconium oxide and other high-strength ceramic materials, including aluminum oxide and pressed ceramics. Incorporating interspersed diamonds for consistent performance, ZR polishers produce an outstanding shine in just two steps - blue for pre-polishing and light gray for high-shine final polishing. Each color polisher is available in three sizes and with golden shanks.
