Kennametal 7096842 Grooving Insert A4R Carbide Altin

Product Description

The KENNAMETAL 7096842 is a carbide grooving insert in the A4R style, designed for precision grooving and parting operations on CNC lathes and turning centers. It features a 0.0790-inch (2.000 mm) cutting width and a maximum depth of cut of 0.0650 inches (1.65 mm). The insert is finished with an AlTiN coating applied via PVD process, grade KCU10B, which provides thermal resistance and extended tool life in demanding cut conditions. The full-radius geometry and positive rake angle support clean chip formation in ferrous and non-ferrous workpiece materials. Licensed machinists and CNC programmers working in job shops or production turning environments are the primary users.

This insert is suited for external grooving applications on turning centers where tight groove widths and controlled depth are required. The double-end configuration and two cutting edges per insert improve cost-per-edge value in high-cycle production environments. The neutral hand orientation makes it adaptable to standard A-series grooving toolholders. The GMP chip breaker geometry is intended for general-purpose grooving across a range of materials and feed rates.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or removing inserts. Use the appropriate torx or hex key to engage the clamping mechanism evenly - avoid over-torquing the clamp screw. Verify insert seating and edge condition visually before resuming cutting operations.
