Spearhead High Speed Steel 90 Degree Bearing Bur Master Kit of 33 Pieces

Spearhead High Speed Steel 90 Degree Bearing Bur Master Kit

Otto Frei carries the Spearhead brand of High Speed Steel (HSS) 90 degree setting burs which are hand cut by expert craftsmen in the USA. You can always recognize the Spearhead brand of HSS burs by the size stamped on the 3/32" shanks. While more expensive than imported Tungsten Vanadium Carbon Steel Burs, these HSS burs will stay sharp and give a longer service life than the not as hard machine cut Tungsten Vanadium burs. HSS burs are preferred by quality jewelers everywhere.

This is the complete set of Spearhead HSS 90 Degree Setting burrs. Set includes one each of the following burs:
