Carbide Inside Ring Cylinder Finishing Burs-Fine to Coarse

These burs trim and true the inside of a ring band, cutting fast and staying controlled as you clean up the interior after sizing or casting. The cylinder head is sized specifically for inside ring work and seats solidly in a 3/32" collet, so the cut feels stable and predictable on a flex shaft or micromotor. Four cutting aggressions, Fine through Extra Coarse, cover every stage of interior ring work, from light refining to heavy stock removal.

Notes

Use light, controlled pressure and let the bur do the work when trimming ring interiors, especially in softer alloys. Keep burs clean and free of loading to maintain cutting efficiency.
