A 90-degree bearing bur cuts the flat-bottomed seat that a stone sits down into, and this kit covers the range a setter reaches for most.
Spearhead High Speed Steel (HSS) 90 degree bearing burs are hand cut by expert craftsmen in the USA and are a preferred choice of quality jewelers everywhere. Each bur in the Spearhead line features the size stamped directly on the 3/32" shank, making identification fast and reliable at the bench. Compared to imported Tungsten Vanadium Carbon Steel burs, these HSS burs are harder, stay sharper longer, and deliver extended service life, making them a smart investment for professional stone setting work.
This 14-piece kit spans from size No. 1 (0.90 mm) through size No. 28 (7.2 mm), giving you a comprehensive range of 90 degree setting burs to handle a wide variety of stone sizes in a single set. The burs are supplied in a 36-hole wood bur box sized for 3/32" shanks, measuring 5" wide by 3" deep by 2-5/8" high, so every size has its own seat on the bench.
Everything in the box.
