Kennametal 4175953 Grooving Insert NR3047K KCU10 Carbide

Product Description

The KENNAMETAL 4175953 is a solid carbide grooving insert in the Top Notch series, designed for precision grooving and turning operations on CNC lathes and turning centers. It carries the NR insert style with a KCU10 manufacturer grade and an AlTiN coating applied via PVD process, providing enhanced wear resistance and thermal stability at the cutting edge. The insert is configured for left-hand cutting with a 2.39 mm cutting width and a maximum depth of cut of 3.81 mm. Cutting height measures 8.74 mm and overall length is 0.8825 inches. This insert is intended for use by machinists and tooling professionals in production and job-shop turning environments.

The 4175953 is suited for grooving, parting, and profiling operations on metal workpieces in both production and maintenance machining contexts. The full-radius geometry and 55-degree included angle make it appropriate for applications requiring a controlled corner profile. The K chip breaker designation is optimized for chip management in continuous grooving cuts. Insert size 3047 places it in a standard Top Notch toolholder class compatible with NR-style clamp-type holders. Material grades C3 and C4 indicate suitability for machining cast iron and nonferrous materials as well as general-purpose steel applications.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before changing inserts. Seat the insert fully in the pocket and confirm the clamp applies even, secure pressure before resuming cuts. Do not exceed the rated maximum depth of cut for the insert size.
