Tungaloy Corp.’s TetraMini-Cut series features a compact four cornered insert that is clamped in a pocket for indexing repeatability and tool life stability, says the company.

According to the company, the series includes two chipbreaker styles. The TCG style chipbreaker incorporates rake angle and edge preparations while the TCP style chipbreaker features a large rake angle with a sharp cutting edge. Its maximum depth of cut is now extended to 3.5 mm (0.14”) from 2.5 mm (0.01”). To meet the requirements from small and miniature part manufacturers who are grooving with R0.1 mm (R0.004”) or smaller, the TCP line also includes inserts with R0.05 mm (R0.002”) corner radii.

The extended TetraMini-Cut line also includes the AH7025 grade featuring a nano-multilayer PVD coating with high aluminum content.
