Spearhead High Speed Steel 45 Degree Bearing Bur Kit of 24 Pieces

Otto Frei carries the Spearhead brand of High Speed Steel (HSS) 45 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 45 degree bearing burs will stay sharp and give a longer service life than the not as hard machine cut Tungsten Vanadium burs. HSS heart (or hart) burs are preferred by quality jewelers everywhere.

This set contains the first 24 of the line of HSS 45 degree bearing or setting burs. The set covers the range from No. 2 (1.1mm) to No. 30 (8.0mm). This set does not include No. 34 (11.1mm) which is available separately as Otto Frei part #119.414

There are no numbers 1,21,23,25,27,29,31 and 33 made in the HSS 45 degree bearing bur line.
