Kennametal 1163214 NPR51 KC730 Profiling Insert Carbide

Product Description

The KENNAMETAL 1163214 is a solid carbide profiling and turning insert in the Top Notch series, designed for high-performance material removal on CNC lathes and turning centers. It carries the KC730 grade with a PVD-applied TiN coating, delivering wear resistance and edge integrity across demanding cutting applications. The insert features a parallelogram shape with a 55-degree included angle, a negative rake of 10 degrees, and four usable cutting edges, making it an efficient choice for shops that prioritize cost-per-edge economics. A corner radius of 0.0156 inches and a maximum depth of cut of 0.1256 inches suit it for profiling passes requiring controlled surface geometry. Licensed machinists and CNC turning technicians are the primary installers of this tooling.

This insert is suited for profiling and turning operations on steel, stainless steel, superalloys, and titanium workpieces, covering ISO material codes P, M, and S. It is appropriate for material grades P10, P20, M10, M20, S10, and S20. The screw-clamped, right-hand insert orientation makes it compatible with right-hand Top Notch toolholders. It is applicable in both roughing and finishing profiling passes where a consistent corner radius and reliable chip control are required.

Key Features

• KC730 grade with PVD TiN coating for extended tool life on ferrous and exotic alloys
• Four cutting edges per insert for lower cost-per-edge in production turning
• 55-degree included angle in a parallelogram shape for profiling versatility
• Negative rake geometry with 0-degree relief angle suited for stable, rigid setups
• Corner radius of 0.0156 inches for controlled surface finish on profiling passes
• Screw-holding method for positive, repeatable insert location in the toolholder pocket

Compatibility

Designed for use with right-hand Top Notch series toolholders accepting the NPR51 insert style. ISO code reference is KCGX110304R15. Standards compliance listed as NPR51 and KCGX110304R15.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC tooling technician with the machine in a full stop, locked-out state. Use the manufacturer-specified torque driver for the clamping screw to avoid seat distortion or screw shear. Inspect the toolholder pocket and seating surfaces for chips or damage before seating each new cutting edge. Always verify insert orientation and overhang before resuming the cut.
