Busch Fig. 156C Hart 90 Degree Burs 4.00mm-5.00mm

A 90 degree hart bur cuts the angled seat a stone beds into, opening a clean bearing at a fixed angle for setting work. Busch is the most trusted name in jewelers' burs, and the Fig. 156C Hart 90 Degree Bur upholds that reputation with precision craftsmanship built for professional metalsmithing and stone setting. Known in Europe as Fig. 414 and in the USA as Fig. 156C, these burs are machined from tungsten vanadium steel to ultra-high precision tolerances, delivering consistent, reliable performance cut after cut.
