Kennametal 7093288 Wnmg Turning Insert Carbide Altin

Product Description

The KENNAMETAL 7093288 is a WNMG-style indexable turning insert designed for metal-cutting lathe operations. Built from carbide substrate with an AlTiN (aluminum titanium nitride) coating and KENNAMETAL KCU10B grade designation, this insert delivers wear resistance and thermal stability across a range of turning applications. The trigon (W) insert shape provides an 80-degree included angle, and the FP chip breaker geometry controls chip flow during continuous turning cuts. With six cutting edges per insert and a 0.0157 inch corner radius, this is a cost-effective consumable for production turning environments. Licensed machinists and CNC lathe operators are the primary installers.

This insert is suited for external and internal turning operations on CNC lathes and manual engine lathes. The neutral hand orientation allows use in both right-hand and left-hand toolholders depending on setup. The FP chip breaker geometry is typically applied to finishing and medium turning passes on steel and similar workpiece materials. The KCU10B grade with AlTiN coating is intended for dry or semi-dry cutting conditions where heat resistance at the cutting edge is a priority.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Before indexing or replacing inserts, power down the spindle and confirm the machine is in a safe lockout state. Seat the insert fully against the pocket locating surfaces and torque the clamping screw according to the toolholder manufacturer specification. Inspect the insert seat and chip pocket for chips or debris before seating a new edge.
