Product Description: Traditional diamond instruments often clog during the bulk reduction task in crown preparation, particularly when cutting non-brittle substrates like amalgam. There is no clear way to wash away the debris. As a result, diamonds quickly lose their cutting efficiency. Unlike diamond instruments, the Great White Ultra carbide is designed to provide high-speed performance with minimal clogging.
