Kennametal 4176110 Grooving Insert NR4094K KCU10 Carbide Altin

Product Description

The KENNAMETAL 4176110 is a solid carbide grooving insert in the Top Notch series, designed for turning and grooving operations on CNC lathes and manual turning centers. It carries the NR4094K insert style designation and is coated with AlTiN via a PVD process, providing heat resistance and extended tool life in ferrous and difficult-to-machine materials. The cutting width measures 0.1882 inches, the cutting height is 0.4530 inches, and the maximum depth of cut is 0.25 inches. A full-radius geometry with a corner radius of 0.0941 inches helps produce consistent groove profiles. The KCU10 grade is suited for demanding interrupted-cut and finishing applications. Installed by machinists and CNC tooling technicians in production and job-shop environments.

This insert fits right-hand toolholders in the Top Notch series, insert seat size 4. It is appropriate for grooving, parting, and profiling on workpieces where a 0.1882-inch-wide groove and a depth range of 0.2000 to 0.3000 inches is required. The K chip breaker geometry assists with chip control during grooving passes. With a lead angle of 0 degrees and a full-radius profile, this insert is well suited to standard radial grooving on bar stock, tubing, and turned components in both production runs and single-part setups.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician with the machine in a full stop and locked-out condition. Seat the insert firmly against the pocket and verify the clamping screw torque per the toolholder manufacturer specification before taking any cut. Inspect the insert seat and clamping components for chips or debris before seating a new insert, as contamination will affect insert position and tool life. Do not exceed the stated maximum depth of cut range for this insert style.
