Busch Fig. 413 Setting Burs 4.00mm-8.00mm

A setting bur cuts the seat inside a prong head or bezel so the stone's girdle drops in level and holds securely. Busch Fig. 413 setting burs do that work in tungsten vanadium steel, precision-ground to ultra-high tolerances for consistent, repeatable results across a wide range of seat diameters.

This listing covers the larger end of the family: nine sizes from 4.00mm – 8.00mm, each sold individually so you buy only the diameter the job calls for.
