Manufactured to the NG insert style with a KCU25 grade substrate and an AlTiN coating applied via PVD process, this insert delivers heat and wear resistance in demanding cutting applications. The left-hand orientation and K chip breaker geometry suit controlled grooving passes at a cutting width of 1.19 mm (0.0469 inches) and a maximum depth of cut of 1.91 mm (0.0752 inches). Installation requires a compatible Top Notch clamp-style toolholder. Machining professionals and toolroom technicians specify this insert for precision grooving work.\u003c\/p\u003e\u003cp\u003eThis insert is suited for grooving operations in ferrous and non-ferrous materials where a tight cutting width and controlled chip formation are required. The double-end configuration allows for extended service life per insert. The insert size 3047 with seat size 3 fits into Top Notch series toolholders designed for that seat designation. Typical applications include OD grooving, undercut profiling, and narrow parting passes on production turning equipment in job shop and manufacturing environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with KCU25 manufacturer grade for wear resistance in demanding cuts\u003c\/li\u003e\n\u003cli\u003eAlTiN coating via PVD process provides thermal barrier and extended tool life\u003c\/li\u003e\n\u003cli\u003eLeft-hand insert orientation with K chip breaker geometry for controlled chip evacuation\u003c\/li\u003e\n\u003cli\u003e1.19 mm cutting width with a maximum depth of cut of 1.91 mm\u003c\/li\u003e\n\u003cli\u003eDouble-end insert design extends usable life per unit\u003c\/li\u003e\n\u003cli\u003eClamp-style holding method compatible with Top Notch series toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series clamp-style grooving toolholders accepting insert seat size 3 and insert size 3047.
