Fox Fig. 1 Ball Burs 0.30mm-3.70mm

A ball bur cuts the seat a stone sits in, opens a bearing, and clears fine detail work at the bench, and this figure covers that job from micro pavé through larger seats. Fox Fig. 1 Ball Burs are precision-manufactured tungsten vanadium steel rotary instruments made in Germany by Brasseler, and they come in 30 micro and standard sizes from 0.30 mm to 3.70 mm. Consistent sizing, a smooth cutting action, and long service life make them a dependable choice for stone setting, pavé work, seat cutting, and fine detail operations. Each size is sold in a pack of 6.
