Important Notice: This set will ship incomplete. Due to ongoing supply constraints, Spearhead has been unable to fulfill all sizes in this kit as ordered. Otto Frei will contact you with the exact burs in stock, the sizes unavailable, and an updated reduced kit price at the time of your order. We are not back-ordering missing sizes, as restocking timelines are unknown and inventory returns randomly. For reference, as of 7/29/2026, 15 of the 23 sizes were available — actual stock will vary on your order date.
Spearhead High Speed Steel (HSS) burs are hand cut by expert craftsmen in the USA. You can identify genuine Spearhead HSS burs by the size stamped directly on their 3/32" shanks. Compared to imported Tungsten Vanadium Carbon Steel burs, these HSS burs are harder, stay sharper longer, and deliver a significantly extended service life. HSS burs are the preferred choice of quality jewelers worldwide.
This master kit is the complete range of HSS Bud Burs, spanning from size No. 2 (1.10 mm) through size No. 34 (11.1 mm) — every bud bur size that Spearhead produces. Note that sizes 1, 15, 17, 19, 21, 23, 25, 27, 29, 31, and 33 are not manufactured in the bud shape and are not part of this set.
