It carries the NPL505 insert style designation and Kennametal grade K313, a fine-grain uncoated carbide grade suited for demanding finishing and profiling operations. The insert features a parallelogram shape with a 55-degree included angle, negative rake geometry, and a 0-degree relief angle. With four cutting edges and a corner radius of 0.005 inches, it delivers consistent edge performance in high-precision turning and profiling applications. Licensed machinists and CNC lathe operators are the primary installers of this insert type.\u003c\/p\u003e\u003cp\u003eThis insert is intended for profiling and turning operations on non-ferrous metals, superalloys, and titanium workpieces. Its left-hand orientation and screw-holding method make it suitable for use in compatible Top Notch toolholders configured for left-hand cutting. The uncoated WC-Co surface finish and fine-grain carbide substrate are well-matched to applications where edge sharpness and surface finish quality are critical, such as aerospace component turning or precision contour work on titanium and nickel-based alloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide grade K313 with fine-grain microstructure for consistent edge integrity\u003c\/li\u003e\n\u003cli\u003eUncoated WC-Co finish optimized for non-ferrous metals, superalloys, and titanium\u003c\/li\u003e\n\u003cli\u003eParallelogram shape with 55-degree included angle and negative rake geometry\u003c\/li\u003e\n\u003cli\u003eFour cutting edges maximize insert utilization per unit\u003c\/li\u003e\n\u003cli\u003eLeft-hand cutting orientation with screw insert-holding method\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.005 inches (0.10 mm) for controlled surface finish in profiling passes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in Top Notch series toolholders configured for left-hand NPL505 inserts.
