Kennametal 4109675 Grooving Insert NG2062 KCU25 Solid Carbide

Product Description

The KENNAMETAL 4109675 is a solid carbide grooving insert in the Top Notch series, designed for precision external grooving and turning operations on CNC lathes and turning centers. Manufactured to the NG insert style with a KCU25 grade and PVD-applied AlTiN coating, it delivers heat resistance and wear performance in demanding cutting applications. The insert provides a 1.58 mm (0.0622 inch) cutting width and a maximum depth of cut of 2.79 mm (0.1098 inch), making it well suited for shallow to moderate grooving work in steel, alloy, and similar workpiece materials. It is installed and replaced by machinists and CNC tooling technicians.

This insert is intended for use in Top Notch series toolholders that accept a size 2 insert seat. It is configured for right-hand cutting and features a double-end design, extending usable tool life per insert. The included angle of 55 degrees and a corner radius of 0.19 mm (0.0075 inch) make it appropriate for grooving profiles requiring a near-full-radius tip geometry. Typical applications include external groove turning on production and job-shop turning equipment in metalworking environments.

Installation Notes

Installation and 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 clamp hardware specified for the Top Notch toolholder to secure the insert without over-tightening. Inspect the insert seat and clamping components for debris or wear before seating a new insert. Follow the toolholder manufacturer guidelines for indexing and insert retention.
