Kennametal 4175860 Grooving Insert NG2125 KCU10 Carbide Altin

Product Description

The KENNAMETAL 4175860 is a solid carbide grooving insert in the Top Notch series, designed for external grooving and parting operations on CNC lathes and turning centers. It carries a KCU10 manufacturer grade with a PVD-applied AlTiN coating, delivering high wear resistance and thermal stability across a range of workpiece materials rated C3 and C4. The insert is left-hand orientation with a 3.18 mm cutting width, a maximum depth of cut of 2.79 mm, and a corner radius of 0.19 mm. Machinists and CNC operators install this insert as a direct-fit component into compatible Top Notch clamp-style toolholders.

This insert is suited for precision grooving applications on lathes in metalworking environments, including production shops and job shops running turning operations on ferrous and non-ferrous materials. The NG style insert size 2125, combined with the AlTiN PVD coating, makes it appropriate for moderate to high cutting speeds where heat buildup and abrasive wear are primary concerns. It is installed using a clamp-style insert holding method standard to the Top Notch toolholder system. The 55-degree included angle and full-radius-free geometry support controlled chip formation in narrow groove profiles.

Compatibility

Designed for use with Top Notch series clamp-style toolholders accepting NG-style inserts. The MSC and manufacturer cross-reference number for this insert is NG2125R/L.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician with the machine powered down, spindle stopped, and all energy isolated per lockout/tagout procedures. Seat the insert fully against the toolholder pocket before tightening the clamp to manufacturer torque specifications for the toolholder model in use. Inspect the insert seat and clamp for chips or debris before each insert change. Do not exceed the maximum depth of cut range of 2.00 mm to 3.00 mm for this insert grade and geometry.
