Unmatched in versatility and performance, ZR-Diamonds address these real, everyday challenges by providing superior results quickly and with minimal effort. Offered in a range of shapes and sizes, ZR-Diamonds provide an effective, efficient, and easy-to-use option for adjusting high-strength ceramic restorations. Other features and benefits include:

• Permanently bonded, high-quality diamond particles
• Densely packed diamond layer
• Outstanding durability & extended service life

Indications for Use

Crown and bridge technique. Grinding all types of ceramics including zirconia.

Laboratory Use

For efficient post-processing of zirconium oxide.

Due to its high strength, zirconium oxide places high demands on its processing. In view of the high material hardness of the zirconium oxide, conventional grinders have too little service life and wear out very quickly. With the ZR grinder, a special diamond tool is available for first-class post-processing of zirconium oxide.
