Kennametal 1849055 NPL505 KC5010 Carbide Profiling Insert

Product Description

The KENNAMETAL 1849055 is a carbide profiling and turning insert in the NPL series, designed for precision metal removal 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 parallelogram-shaped insert features a 55-degree included angle, a 0.10 mm corner radius, and a negative rake geometry with zero relief angle. It is held in place by a screw-clamp method and provides four usable cutting edges per insert, making it a cost-effective option for high-volume turning and profiling operations.

This insert is suited for profiling and turning applications on steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. It covers ISO material grades P10, P20, M10, M20, K05, K10, K15, K20, N10, N20, S10, S20, and H10. Typical applications include contour turning, shoulder profiling, and copy turning where consistent edge geometry is required. The left-hand designation determines the compatible toolholder orientation. This insert is used by machinists and toolroom professionals in both production and job-shop environments.

Key Features

• KC5010 grade with AlTiN PVD coating for extended tool life on ferrous and exotic materials
• Four cutting edges per insert for reduced cost-per-edge
• 0.10 mm corner radius for defined profiling and finishing cuts
• Negative rake, zero relief angle geometry for stable, chatter-resistant cuts
• Screw-clamp insert holding method for secure, repeatable seating
• Parallelogram shape with 55-degree included angle suits V-style and profiling toolholders

Compatibility

Designed for use in NPL-series left-hand toolholders accepting NPL505 inserts. ISO code KCGX110301L15 identifies compatible holder and pocket geometry. Verify holder designation and insert hand before ordering.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before changing inserts. Use the correct torque screwdriver or hex key specified by the toolholder manufacturer when seating the clamping screw — do not overtighten, as this can crack the carbide insert. Confirm insert seating and edge indexing before resuming cutting operations.
