Kennametal 7090554 Cngg Turning Insert Carbide Altin

Product Description

The KENNAMETAL 7090554 is a CNGG-style carbide turning insert designed for precision metal cutting in CNC lathe and turning center applications. Built from carbide substrate in grade KCU10B with an AlTiN coating, this insert delivers thermal and wear resistance suited for demanding cutting conditions. The diamond-shaped insert body features an 80-degree included angle, a 0.008 inch corner radius, and a neutral hand orientation. With four available cutting edges, it offers extended tool life and cost efficiency per edge. It weighs 0.03 pounds and is sold individually with a minimum order quantity of five.

This insert is suited for finish and semi-finish turning operations in general machining environments, including steel and ferrous material applications where a sharp, consistent edge is required. The CNGG style with FS chip breaker geometry is appropriate for light to moderate depth-of-cut scenarios requiring controlled chip formation. Machinists and CNC operators in job shops, production machining facilities, and aerospace component manufacturing environments commonly specify this insert type.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician following the machine tool builder guidelines. Power down and lock out the machine spindle before changing inserts. Use a torque wrench calibrated to the toolholder manufacturer specification when securing the clamp screw, and inspect the insert seat and clamp for debris or wear before seating the insert. Never operate a cracked or chipped insert.
