Busch Fig 411T Twincut Concave Cup Bur Kit of 12-0.80mm to 2.00mm

A cup bur rounds the tip of a prong cleanly and consistently, the number one application for cup burs in jewelry work. Busch Fig. 411T twincut concave cup burs are precision engineered in Germany from tungsten vanadium steel to ultra-high tolerances, and this kit of 12 brings together one bur in each size of the full 411T range, from 0.80 mm to 2.00 mm.

The twincut blade geometry is the defining feature of the Fig. 411T series, delivering a smooth, controlled cutting action. The concave cup shape, the traditional form jewelers have relied on for generations, rounds the tip of a prong cleanly and produces a finished look that protects stones. The kit is supplied in a plastic bur box with 48 holes for 3/32 in shank burs.
