Kennametal 1792683 Grooving Insert KC5025 Carbide Tialn

Product Description

The KENNAMETAL 1792683 is a solid carbide grooving insert designed for precision external grooving and turning operations on CNC lathes and turning centers. Manufactured to the NR3047K insert style within the Top Notch series, it features a TiAlN coating applied via PVD process, which delivers thermal resistance and extended tool life in demanding cutting environments. The insert provides a cutting width of 2.39 mm (0.0941 inches) and a maximum depth of cut of 3.81 mm (0.1500 inches). The positive rake geometry combined with the K chip breaker promotes clean chip evacuation and reduces cutting forces during grooving passes. This insert is installed and serviced by machinists and CNC tooling technicians working in production and job-shop environments.

This insert is suited for grooving applications in both production and prototype turning operations. The KC5025 grade with PVD TiAlN coating is formulated for performance in a range of workpiece materials where wear resistance and edge integrity are critical. The right-hand orientation determines holder and approach compatibility on the machine setup. The full corner radius of 1.19 mm (0.0469 inches) and the 55-degree included angle are relevant factors when matching this insert to groove profile requirements. It is intended for use in Top Notch series compatible toolholders.

Key Features

• Solid carbide construction in manufacturer grade KC5025 for wear resistance in grooving applications
• TiAlN coating via PVD process for thermal and oxidation resistance at the cutting edge
• 2.39 mm cutting width with a maximum depth of cut range of 3.00 to 4.00 mm
• Full radius corner geometry with 1.19 mm corner radius for consistent groove profile
• Positive rake angle of 10 degrees with K chip breaker for controlled chip formation
• Right-hand insert orientation; NR insert style within the Top Notch series

Compatibility

Designed for use with Top Notch series compatible grooving toolholders that accept the NR3047 insert size. The MSC and manufacturer cross-reference number for this insert is NR3047R/LK. Confirm holder compatibility and insert seat dimensions before installation.

Installation Notes

Installation of grooving inserts should be performed by a qualified machinist or CNC tooling technician with the machine spindle fully stopped and all motion axes locked out per facility lockout/tagout procedures. Use the appropriate insert seating tool or torx key specified for the Top Notch toolholder to secure the insert without overtightening the clamping screw. Inspect the insert pocket and clamping components for wear or debris before seating the new insert. Verify tool offset and depth-of-cut parameters in the CNC program before resuming cutting operations.
