Kennametal 4109804 Grooving Insert NG3097 KCU25 Left Hand

Product Description

The KENNAMETAL 4109804 is a solid carbide grooving insert in the Top Notch series, designed for external grooving and cutoff operations on CNC lathes and turning centers. It carries a KCU25 manufacturer grade with an AlTiN finish applied via PVD coating, providing wear resistance and thermal stability in demanding cutting applications. The insert features a 2.46 mm cutting width, a maximum depth of cut of 3.81 mm, and a corner radius of 0.32 mm. Left-hand orientation is standard for this part. It is held in place by a clamp-style toolholder. Machinists and CNC operators working in production turning environments install and replace these inserts as part of routine tooling maintenance.

This insert is suited for grooving applications on lathes equipped with Top Notch compatible toolholders. The KCU25 carbide grade with AlTiN PVD coating performs well in interrupted cuts and on a range of workpiece materials where toughness and coating adhesion matter. The left-hand configuration suits specific spindle orientations and toolholder setups common in production turning cells. This is a single-insert package sold in minimum order quantities of 5 units.

Installation Notes

Insert replacement should be performed by a qualified machinist or CNC tooling technician with the machine powered down and the spindle fully stopped. Use the appropriate torque wrench and clamping hardware specified for the Top Notch toolholder to seat the insert securely before resuming operation. Inspect the insert pocket and clamp for wear or debris before installing a new insert. Do not exceed the rated maximum depth of cut for this insert size.
