Swiss-Type Grooving Tools Extended to General Lathe Market

Tungaloy is broadening its TetraMini-Cut series of grooving tools for Swiss-type machines to include new insert lines for the general lathe market. The products feature compact, four-cornered inserts that are securely clamped in a pocket for indexing repeatability and tool life stability.

The line now includes two chipbreaker styles. The TCG chipbreaker incorporates optimized rake angle and edge preparations and is suited for the automotive industry. The TCP chipbreaker features a large rake angle with a sharp cutting edge. Its maximum depth of cut is 3.5 mm (0.14"), enabling a range of applications. To meet the requirements of small and miniature part manufacturers grooving with R0.1 mm (R0.004") or smaller, the TCP line also includes inserts with R0.05-mm (R0.002") corner radii.

The series also includes the AH7025 grade, featuring a nano-multilayer PVD coating with high aluminum content for cutting various materials while minimizing common grooving issues including chipping, fractures and plastic deformation on the cutting edge.
