Kennametal 7097848 Grooving Insert A4R Carbide 0.1870in

Product Description

The KENNAMETAL 7097848 is a carbide grooving insert designed for precision grooving and parting operations on CNC lathes and turning centers. Built to the A4R insert style with a size code of 4, it delivers a cutting width of 0.1870 inches (4.760 mm) and a maximum depth of cut of 0.1490 inches (3.80 mm). The insert is coated with AlTiN via a PVD coating process, grade KCU10B, providing wear resistance in demanding turning applications. With a positive rake geometry and GMN chip breaker, it promotes controlled chip evacuation and reduces cutting forces during grooving cycles.

This insert is suited for production turning environments where consistent groove geometry and tool life are priorities. Its neutral hand configuration makes it adaptable across standard grooving toolholders using a clamp-style insert holding method. The double-end design provides two usable cutting edges, extending value per insert. It is appropriate for grooving ferrous and non-ferrous materials in both roughing and finishing passes, and is commonly used by machinists in job shops and high-volume production cells.

Installation Notes

Installation should be performed by a qualified machinist with the machine in a full stop and lockout-tagout procedures in effect. Ensure the toolholder seat and clamping surfaces are clean and free of chips before seating the insert. Use the appropriate torque tool for the clamp screw as specified by the toolholder manufacturer. Inspect the insert seat size and orientation before engaging the workpiece.
