Configured in the CNGA431 style with an 80-degree diamond shape, this insert features a neutral hand orientation, a negative rake angle, and a honed cutting edge for consistent performance on hardened steels and other difficult workpiece materials. The insert carries a BX310 manufacturer grade, is uncoated (bright finish), and belongs to the 2QP-CNM\/GA series. It provides two cutting edges per insert and is held via clamp and pin mounting. Qualified machinists and CNC tooling specialists use this insert for turning, facing, and boring operations where tool life and dimensional accuracy are critical.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for finishing and semi-finishing operations on hard materials in both production and job-shop environments. Its multi-tipped, flat-top chip breaker geometry and medium grain PCBN construction make it appropriate for interrupted and continuous cuts on hardened ferrous components. The 2QP-CNM\/GA series targets applications where ceramic or carbide inserts reach their performance limits. Compatible with CNGA-style insert pockets and toolholders designed for 80-degree diamond inserts with a 1\/2 inch inscribed circle.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePCBN insert material rated for hard material workpieces (ISO material group H)\u003c\/li\u003e\n  \u003cli\u003eBX310 grade, medium grain, uncoated bright finish  -  no coating delamination risk\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (Shape Code C) for versatile turning, facing, and boring\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert for extended tool economy\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge with flat-top chip breaker and 0 degree rake angle\u003c\/li\u003e\n  \u003cli\u003eClamp and pin holding method for secure, repeatable seating in compatible toolholders\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards; ISO code 2-QPCNGA431\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNGA-style insert pockets accepting an 80-degree diamond insert with a 1\/2 inch inscribed circle, 3\/16 inch thickness, and clamp-and-pin holding.
