High Speed Steel Cylinder Burs 1.70mm-11.10mm

A cylinder bur cuts precise seats and channel work at the bench. Spearhead High Speed Steel (HSS) cylinder burs are hand cut by expert craftsmen in the USA, offering superior sharpness and longer service life compared to imported Tungsten Vanadium Carbon Steel burs. The harder composition of HSS allows these burs to hold their edge through demanding work, making them the preferred choice of quality jewelers. Each bur features the size stamped directly on its 3/32" shank for quick, reliable identification at the bench.
