Inside Ring Burs: 1/8" (3.18mm) Shank

This version of the extra-fine inside ring bur features a thicker 0.125 inch (3.18 mm) shank, designed for use with heavy-duty handpieces and industrial-scale lathes. The larger shank provides increased stability and less flex during the polishing process, which is ideal for working on larger items or when using higher torque. The extra-fine cut ensures a beautiful, smooth finish that requires minimal buffing to reach a high shine. This is a specialized tool for workshops that utilize larger-capacity rotary equipment for the manufacturing of heavy gold and silver bands.
