Kennametal 1849059 NPL51 KC5010 Carbide Profiling Insert

Product Description

The KENNAMETAL 1849059 is a carbide profiling and turning insert in the Top Notch series, designed for high-performance metal cutting on CNC lathes and turning centers. It carries the KC5010 manufacturer grade with an AlTiN coating applied via PVD process, delivering wear resistance and thermal stability across a broad range of workpiece materials. The insert features a parallelogram shape with a 55-degree included angle, a 0.40 mm corner radius, and a negative rake geometry. Four cutting edges are available per insert, making it an efficient option for production turning environments. Installation is secured by screw clamping.

This insert is suited for profiling and turning operations on steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials, covering ISO material codes P, M, K, N, S, and H. It performs across a wide grade range including P10, P20, M10, M20, K05, K10, K15, K20, N10, N20, S10, S20, and H10. It is a left-hand insert intended for applications where tool path geometry requires left-hand cutting orientation. Typical use cases include finish and semi-finish profiling passes on turned components in job shop and production environments.

Key Features

• KC5010 carbide grade with AlTiN PVD coating for extended tool life on steel and stainless
• Parallelogram shape with 55-degree included angle suited for profiling passes
• 0.40 mm corner radius for controlled surface finish on contoured features
• Negative rake geometry with zero relief angle for rigid, stable cutting
• Four usable cutting edges per insert for cost-effective tooling rotation
• Screw-clamp insert holding method for secure, repeatable seating

Compatibility

Conforms to NPL51 insert standard and ISO code KCGX110304L15. Compatible with Top Notch series toolholders designed for NPL51 inserts with screw-clamp retention.

Installation Notes

This insert is installed by a machinist or toolroom technician into a compatible screw-clamp toolholder. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque driver for the clamping screw to avoid seat damage — follow the toolholder manufacturer's torque specification. Handle carbide inserts with care to prevent chipping of cutting edges prior to use.
