Busch Fig 1 Round Ball Bur Kit of 19 Pieces-0.5mm to 4.0mm

Round ball burs do the everyday work at the bench: opening and enlarging drilled holes, cutting seats, and shaping metal wherever a rounded cut is wanted. This Busch Fig 1 Round Ball Bur Kit gathers the most popular ball bur sizes, from 0.50mm through 4.00mm, with the three highest-demand sizes supplied in duplicate, which makes it both a strong starter set and a way to sample Busch quality across the size range.

Busch burs are the most trusted name in jewelers' burs, known for consistent quality and precision across a wide range of shapes and sizes. Every bur here is genuine Busch tungsten vanadium steel on a 3/32" (2.35mm) shank for quick tool changes. The kit is part of the GIA graduate jeweler program, with sizes chosen by GIA's expert instructors to support their curriculum, and it is stored in a plastic bur box drilled with 48 holes for 3/32" shank burs.
