Sumitomo SumiDia CNMX120404 PCD Diamond Insert

The Sumitomo SumiDia CNMX120404 DA150 PCD Diamond Insert is a single-use, indexable cutting tip from Sumitomo’s SumiDia line, designed for high-precision machining of non-ferrous metals. The CNMX120404 designation identifies an 80-degree diamond-type insert in the CNMX family, paired with the DA150 size, and it is sold as a 1-piece item. This insert sits among other CNMX variants (CNMX120402, CNMX120408, CNMX120412) in Sumitomo catalogs, all offering 80° diamond geometry for binderless PCD tooling. Sumidia PCD inserts are binderless PCD tools optimized for cutting aluminum alloys and other non-ferrous metals, delivering wear resistance and a fine surface finish, which makes CNMX120404 DA150 well-suited for finishing and near-net-shape machining of non-ferrous components where a pristine surface is required. As a Sumitomo product, CNMX120404 DA150 reflects the brand’s emphasis on precision, material-specific inserts designed to maximize tool life and surface quality on non-ferrous materials.
