Kennametal 1163375 NPR505 KC850 Profiling Insert Carbide

Product Description

The KENNAMETAL 1163375 is a solid carbide profiling insert in the NPR505 series, designed for profiling and turning operations on steel and stainless steel workpieces. It carries the KC850 manufacturer grade with a CVD coating classification, though the finish on this insert is uncoated. The parallelogram-shaped insert features a negative rake angle of 10 degrees, a relief angle of 0 degrees, and an included angle of 55 degrees. With four cutting edges and a screw-based holding method, it delivers consistent edge utilization across a range of turning applications. Licensed machinists and CNC lathe operators working in production environments install this insert as part of a Top Notch toolholder system.

This insert is suited for profiling and turning operations in both production and job-shop environments. It is primarily applied to steel and stainless steel workpieces, corresponding to ISO material codes P and M, covering material grades P30, P40, M30, and M40. The right-hand orientation and screw-held mounting make it compatible with standard Top Notch toolholding systems. The ISO code for this insert is KCGX110301R15, and it is also cross-referenced under standards NPR505 and KCGX110301R15.

Key Features

• Solid carbide construction with KC850 manufacturer grade for tough interrupted and continuous cuts in steel
• Four cutting edges maximize insert utilization and lower per-edge tooling cost
• CVD coating classification with uncoated finish suitable for primary steel and stainless steel applications
• Parallelogram shape with 55-degree included angle and negative rake for stable chip formation during profiling
• Screw-held, right-hand insert for secure seating in Top Notch toolholders
• Corner radius of 0.0050 inches (0.10 mm) for fine profiling detail with controlled surface finish

Compatibility

Designed for use in Top Notch series toolholding systems. Compatible insert standards include NPR505 and KCGX110301R15. Intended for right-hand cutting applications on steel and stainless steel workpieces in ISO P and M material categories.

Installation Notes

This insert is installed and replaced by qualified CNC machinists or tool room technicians. Power down and lock out the machine spindle before changing inserts. Use the appropriate Torx or hex key for the insert clamping screw as specified by the toolholder manufacturer. Inspect the toolholder pocket and screw threads for wear or damage before seating a new insert to ensure proper clamping force and edge repeatability.
