Description Technical Specs
 
Jewelers making jewelry by hand and gem setting use burs extensively. These High speed or otherwise know as Highspeed burs are known to last much longer than traditional vanadium steel burs as they provide exceptional cutting efficiency. The shank diameter is 3/32" and will fit most handpieces. They are sold individually.
