Spearhead High Speed Steel (HSS) Cone Burs are hand cut by expert craftsmen in the USA, and each bur is stamped with its size on the 3/32" shank for easy identification at the bench. While HSS burs carry a higher price point than imported Tungsten Vanadium Carbon Steel burs, they maintain a sharper edge longer and deliver superior service life over machine-cut alternatives — making them the preferred choice of quality jewelers everywhere.
This master kit contains one each of every HSS Cone Bur in the Spearhead line, ranging from No. 2 (1.10 mm) through No. 34 (11.10 mm), for a total of 23 pieces. It is an ideal starter set or bench reference collection covering the full size spectrum available in this profile.
