ROLAND offers three new Diamond-Coated Dental Milling Burs for its DXW-50 zirconia milling machine. Each tool is engineered for precise performance, maximum durability and long life. The burs are available in three sizes (0.8-, 1- and 2-mm). The design enables the user to produce up to 10 times the number of units that can be milled with a standard carbide bur. Because they are fully compatible with Roland's existing carbide tools, users can switch to the new tools without any changes in the CAM software. Burs are available through Roland dealers and online at the Roland DGA Store. Cost: $170. For more information, call 800-542-2307 or visit www.rolanddga.com.
