Komet has expanded its line of DCB (diamonds with ceramic bond) abrasives to include a small-diameter (4.8 mm), 13-mm-long cylinder-shape grinder, the DCB 2, in addition to the 6.5-mm-in-diameter, 13-mm-long cylinder-shape version (DCB 2 C).
The DCB abrasives have a ceramic bond interspersed with a high content of diamond grit to work with all types of ceramics, including zirconium oxide and aluminum oxide, and hard dental alloys, according to the company.
The array of DCB instruments also includes the DCB 1 flame-shape abrasive, the DCB 3 and 3C tapered-cylinder grinders, the DCB 4 and 4C flat-edge (12-mm-in-diameter) and the DCB 5 knife-edge (22-mm-in diameter) disk configurations, and the DCB 6 cup-shaped abrasive.
The DCB 2 abrasive is recommended for operation at a minimum speed of 12,000 rpm and a maximum speed of 30,000 rpm.
