TNMA 160412 Chip Breaker BC Grade FM524 / TNMA 333 BC # FMCarbide

TNMA 160412 / TNMA 333, chip breaker BC, grade FM524 — negative triangular turning insert.

3/8" inscribed circle, 3/16" thick, 3/64" corner radius. The BC breaker is the medium roughing & cast iron geometry: 0.008–0.020 ipr (0.2–0.5 mm/rev) at 0.06–0.16" (1.5–4 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.
