The Bob Winter Restorative Design Prep Kit #K0197 contains all five depth-cutting burs. The RW 2.0 is a 2-mm reduction bur to be used as an anterior incisal-edge depth guide for ceramic veneers when no core is required, and as a posterior occlusal depth guide for posterior ceramic restorations. The RW 2.5 is a 2.5-mm reduction bur for use as an anterior incisal-edge depth guide for extensive veneers and for full-crown restorations, and provides a 2-mm space for layering ceramic and a 0.5-mm space for the core material (metal, zirconia, etc).
The RW Mand is a labial depth-cutting bur that provides 0.7-mm reduction in the incisal one third, 0.5-mm reduction in the mid tooth, and 0.3-mm reduction in the gingival one third. The RW Max is a labial depth-cutting bur that provides 0.9-mm reduction in the incisal one third, 0.7-mm reduction in the mid tooth, and 0.5-mm reduction in the gingival one third. The RW Press is a labial depth-cutting bur that provides 1.2-mm reduction in the incisal one third, 1-mm reduction in the mid tooth, and 0.8-mm reduction in the gingival one third.
