Jewell Group 1002-71 Indexable Carbide Insert Boring Bar

The Jewell Group 1002-71 is a new, unused indexable boring bar manufactured by Jewell Group (jewellgroup.com), a U.S.-based precision tooling company operating under their Tool Technology brand. The bar features a round shank with a angled insert pocket at the cutting end that accepts a small carbide insert secured by a torx clamp screw, visible in the photos; the insert pocket geometry indicates a negative or neutral rake configuration suitable for internal diameter turning and boring operations. The shank is cylindrical and ground to a consistent diameter along its full length, with a flat relief ground into the cutting end to provide clearance — consistent with Jewell Group's precision-ground boring bar designs intended for CNC lathes and boring mills. The tool is presented in Jewell Group's standard red plastic protective case, confirming new/unused condition and original packaging. Buyers should verify bore diameter compatibility, insert style, and minimum bore diameter directly against Jewell Group's published specifications for part number 1002-71 before purchasing.
