It carries a KCU25 grade designation with a PVD-applied AlTiN coating, offering heat resistance and edge durability in demanding turning applications. The insert features a 1.19 mm cutting width and a maximum depth of cut of 1.91 mm, making it well suited for narrow groove profiles requiring close dimensional control. Installation uses a clamp-style holding method compatible with Top Notch toolholders. This insert is sold individually and requires a minimum order quantity of 5 units.\u003c\/p\u003e\u003cp\u003eThis insert is intended for use in precision turning and grooving applications on ferrous and non-ferrous workpiece materials, consistent with C2 and C6 material grade classifications. Its left-hand configuration suits specific toolholder orientations on gang-style or turret-style setups. The 64-degree included angle and 0.19 mm corner radius define the insert geometry for controlled groove wall finishes. Machinists and CNC operators working in production or job shop environments are the primary users of this insert type.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with PVD AlTiN coating for extended wear resistance\u003c\/li\u003e\n\u003cli\u003eKCU25 manufacturer grade suited to a range of grooving applications\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\u003eLeft-hand insert orientation for specific toolholder compatibility\u003c\/li\u003e\n\u003cli\u003eClamp-style holding method for secure, repeatable seating in Top Notch toolholders\u003c\/li\u003e\n\u003cli\u003e0.19 mm corner radius and 64-degree included angle for defined groove geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series clamp-style grooving toolholders that accept the NG1047 insert size.
