Busch Fig 411C Fast Cut Concave Cone Cup Bur Kit of 16 Burs 1.00mm - 2.30mm

A cup bur finishes and rounds the top of a prong during stone setting. The Busch Fig. 411C fast cut concave cone cup bur has a concave cone shape that leaves a more sharply sloped, rounded prong tip than a traditional concave cup bur.

This kit holds 16 Fig. 411C fast cut concave cone cup burs, two of each of eight sizes from 1.00 mm to 2.30 mm. The burs are made from tungsten vanadium steel with 3/32 in shafts, and the kit arrives in a plastic bur box with 48 holes for 3/32 in shank burs.
