Tungaloy has expanded its TetraMini-Cut series grooving tool range for Swiss type machines wit new insert lines for CNC lathes and turning centres.

TetraMini-Cut features a compact four-cornered insert that is clamped securely in an innovatively designed pocket for indexing repeatability and tool life stability.

Already successful in the Swiss lathe market, TetraMini-Cut is now expanding its benefits tothe general lathe market. The series now includes two new chipbreaker styles each with optimal cutting edge features.

The new TCG style chipbreaker line incorporates optimized rake angle and edge preparations, benefiting manufacturers in all industry segments, especially automotive. The TCP style chipbreaker line features a large rake angle with a sharp cutting edge. Its maximum depth of cut is now extended to 3.5 mm (0.14 in.) from the conventional 2.5 mm (0.01 in.) for greater range of applications. To meet the requirements from small and miniature part manufacturers who are grooving with R0.1 mm (R0.004 in.) or smaller, the TCP line also includes inserts with R0.05 mm (R0.002 in.) corner radii.

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