Kennametal 4175851 Grooving Insert NG2047K KCU10 Carbide

Product Description

The KENNAMETAL 4175851 is a solid carbide grooving insert designed for precision external grooving and turning operations on CNC lathes and turning centers. Designated style NG2047K in the Top Notch series, it features a KCU10 grade substrate with a PVD-applied AlTiN coating for heat resistance and extended tool life in interrupted cuts and hard materials. The insert is configured for right-hand operation with a 1.19 mm cutting width and a maximum depth of cut of 1.27 mm. A K-style chip breaker geometry promotes efficient chip control in finishing and light roughing passes. Machinists and tool-and-die professionals install this insert into compatible Top Notch clamp-style toolholders.

This insert is suited for grooving operations on small-diameter workpieces where tight tolerances and controlled chip evacuation are critical. The 55-degree included angle geometry and 0.09 mm corner radius support fine finishing passes in ferrous and non-ferrous materials classified under material grades C3 and C4. Typical applications include external grooving, undercutting, and profiling on production turning equipment in both job-shop and high-volume manufacturing environments. The clamp-based insert holding method allows repeatable seating and fast changeover without disturbing the toolholder setup.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before changing inserts. Seat the insert fully against the toolholder pocket and tighten the clamp to the toolholder manufacturer's specified torque. Inspect the insert seat and clamp for chips or debris before seating to ensure accurate positioning and prevent premature edge failure.
