High Speed Steel Inverted Cone Burs 1.70mm-8.00mm

Inverted cone burs cut and shape metal at the bench where a precise, controlled profile is required. Spearhead High Speed Steel (HSS) inverted cone burs are hand cut by expert craftsmen in the USA. Each bur features the size stamped directly on the 3/32" shank, making identification quick and reliable at the bench. While HSS burs carry a higher price point than imported Tungsten Vanadium Carbon Steel burs, their superior hardness delivers a longer service life and sustained sharpness that machine-cut alternatives cannot match. These burs are the preferred choice of quality jewelers.
