Kennametal 4045410 NPL51 KCU10 Carbide Profiling Insert

Product Description

The KENNAMETAL 4045410 is a carbide profiling and turning insert in the Top Notch series, designed for precision metalcutting operations on CNC and manual lathes. It features an NPL51 insert style with a KCU10 manufacturer grade applied via PVD coating process, though the substrate runs uncoated. The parallelogram-shaped insert carries a 55-degree included angle, a 0.40 mm (0.0156 inch) corner radius, and a negative rake geometry. With four cutting edges per insert and a screw-type holding method, it delivers repeatable positioning and efficient edge utilization across a range of workpiece materials.

This insert is suited for profiling and turning applications in both production and job-shop environments. It is rated for use on steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials, corresponding to ISO material codes P, M, K, N, S, and H. The material grade range spans P10, P20, M10, M20, K05, K20, N10, N20, S10, S20, and H10, making it a versatile option for shops that run mixed-material work. The left-hand configuration suits specific toolholder orientations common in profiling setups.

Key Features

• NPL51 insert style with KCU10 grade carbide substrate and PVD coating process
• Four cutting edges per insert for extended tool life and lower per-edge cost
• 0.40 mm corner radius supports fine profiling work and contour turning
• Negative rake and 0-degree relief angle provide stable cutting geometry on hard and abrasive materials
• Screw-type holding method ensures secure, repeatable seating in compatible Top Notch toolholders
• Compatible with a broad ISO material code range: P, M, K, N, S, and H

Compatibility

Designed for use in Top Notch series toolholders accepting NPL51 inserts. ISO code reference is KCGX110304L15. Compatible with the NPL51 and KCGX110304L15 standards as specified by the manufacturer. Left-hand designation requires a left-hand Top Notch toolholder.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before changing inserts. Use the correct torx or hex key specified for the Top Notch screw-clamp system to avoid stripping the clamping screw. Inspect the toolholder pocket for chips or debris before seating a new insert to ensure full contact and accurate edge positioning.
