Featuring the KCU25 grade with a PVD-applied AlTiN coating, this insert delivers thermal resistance and wear performance in demanding cutting applications. The left-hand orientation and K chip breaker geometry suit finishing and light roughing in the Top Notch clamping system. Cutting width is 0.79 mm (0.0311 inches) with a maximum depth of cut of 1.27 mm (0.0500 inches), making it well suited for narrow groove profiles requiring tight dimensional control. Insert size is 2031 with a 55-degree included angle.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use by machinists and tool and die professionals operating metalworking lathes in job shop, production, and maintenance environments. The AlTiN finish extends tool life when cutting ferrous and hardened materials at elevated surface speeds. The K chip breaker configuration manages chip flow in shallow, narrow grooves where evacuation is critical. Minimum order quantity is 5 inserts; packaging is single-unit per package.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with PVD AlTiN coating for thermal and wear resistance\u003c\/li\u003e\n  \u003cli\u003eKCU25 manufacturer grade with C2 and C6 material grade classifications\u003c\/li\u003e\n  \u003cli\u003eLeft-hand insert orientation for compatible Top Notch toolholders\u003c\/li\u003e\n  \u003cli\u003eK chip breaker for controlled chip formation in narrow groove profiles\u003c\/li\u003e\n  \u003cli\u003e0.79 mm cutting width with 0.09 mm corner radius for precise groove geometry\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert holding method for secure, repeatable seating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in KENNAMETAL Top Notch series grooving toolholders that accept NG2031 style inserts with clamp-style holding.
