DNMG 150608 Chip Breaker BL Grade FM2543 / DNMG 442 BL #FMCarbide

DNMG 150608 / DNMG 442, chip breaker BL, grade FM2543 — negative 55° rhombic turning insert.

1/2" inscribed circle, 1/4" 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. FM2543 is a CVD grade — first-choice grade for general steel work — continuous through interrupted cuts across steel applications.
