These burs cut and true the seat that holds a stone, and shape metal in close quarters where a clean, controlled cut matters. Spearhead High Speed Steel (HSS) 45° Hart Burs are precision hand-cut in the USA by expert craftsmen. Known for their exceptional sharpness, durability, and consistency, these burs are the professional jeweler's choice for stone setting and precision metalwork.
Each Spearhead bur is stamped with its size on the 3/32" (2.35 mm) shank for quick identification. Made from premium HSS, they maintain a sharper edge longer and resist heat buildup better than imported tungsten vanadium burs, ensuring smoother, cleaner cuts and extended tool life.
