TNMG 160412 Chip Breaker BC FM2543 / TNMG 333 BC #FMCarbide

TNMG 160412 / TNMG 333, chip breaker BC, grade FM2543 — 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. FM2543 is a CVD grade — first-choice grade for general steel work — continuous through interrupted cuts across steel applications.
