The Ultra-flex Disc is the thinnest disc available to the crown and bridge craftsman. This disc is two-thirds as thin as and more flexible than the Ultra-thin Disc, supplementing the Ultra-thin where maximum thinness is required. These are excellent for interproximals and margins. Made of silicon carbide, the gray color discs work best between 10,000 and 12,000 rpm.
