High Speed Steel Slim Reamer Burs 2.50mm-11.10mm

Important Notice 10/22/26: Spearhead HSS burs have ceased production.  The Spearhead factory has closed and is no longer in business.  As we sell out of sizes these burs will no longer be available.

Slim reamer burs open and true a hole to size with precise, controlled cutting. Spearhead High Speed Steel (HSS) slim reamer burs are hand cut by expert craftsmen in the USA, delivering the sharp edges and extended service life that quality jewelers demand. Each bur is easy to identify by the size stamped directly on the 3/32" shank, a hallmark of the Spearhead brand. While HSS burs carry a higher price point than imported Tungsten Vanadium Carbon Steel burs, their superior hardness means they stay sharper longer and outlast machine-cut alternatives. For jewelers who refuse to compromise on precision and durability, these slim reamer burs are the professional standard.
