Mitsubishi STAWN1350TH VP15TF WSTAR S-TAW Carbide Indexable Drill Insert

This is a new Mitsubishi Materials (DIAEDGE) STAWN1350TH indexable drill insert in grade VP15TF, part of the WSTAR S-TAW series for indexable insert drills. It is a solid carbide insert with the company's proprietary Al-based PVD coating (VP15TF), a general-purpose grade offering a balance of wear resistance and toughness suited to drilling steel, stainless steel, and cast iron. The 1350 designation corresponds to a drilling diameter class of approximately 13.5 mm, and the dogbone-style geometry seats into a WSTAR S-TAW type indexable drill body. The insert features multiple usable cutting edges for economical edge indexing, reducing tooling cost per hole. Sold as one piece per box, manufactured in Japan, and shipped new in the original sealed Mitsubishi DIAEDGE packaging.
