Kennametal 1792685 Grooving Insert NR3062K KC5025 Carbide

Product Description

The KENNAMETAL 1792685 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 the NR3062K style designation with a KC5025 manufacturer grade and a PVD-applied TiAlN coating for heat and wear resistance. The insert delivers a cutting width of 3.18 mm (0.125 inches) and a maximum depth of cut of 3.81 mm (0.150 inches). A full radius corner profile with a 1.59 mm (0.0626 inch) corner radius and a positive 10-degree rake angle promote smooth chip flow. Machinists and CNC operators install this insert as part of a Top Notch toolholder system on production turning equipment.

This insert is suited for grooving and recessing operations in production turning environments, both job shop and high-volume manufacturing. The K chip breaker geometry and positive rake support consistent chip control across a range of workpiece materials. The KC5025 carbide grade with TiAlN PVD coating targets steel, stainless steel, and similar materials where edge toughness and thermal resistance are priorities. It is a right-hand insert with metric sizing, insert size 3062, and is sold individually with a minimum order quantity of 5 units per order.

Compatibility

Designed for use with Top Notch series toolholders that accept NR-style inserts at insert size 3062. The MSC and manufacturer cross-reference number is NR3062R/LK.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. The machine spindle must be brought to a full stop and the toolholder must be secured and free of chips or debris before seating the insert. Verify that the insert is fully seated and locked in the Top Notch toolholder pocket before resuming operation. Do not exceed the rated maximum depth of cut for this insert size.
