TNMG 160408 / TNMG 332, chip breaker BL, grade FM524 — negative triangular turning insert.

3/8" inscribed circle, 3/16" thick, 1/32" corner radius. The BL breaker is the semi-finishing geometry: 0.004–0.012 ipr (0.1–0.3 mm/rev) at 0.04–0.12" (1–3 mm) depth of cut. FM524 is a CVD grade — gray cast iron and very stable steel — the hardest substrate with CVD coating for extreme wear resistance.
