Kennametal 7090445 Cnmg Turning Insert Diamond Carbide

Product Description

The KENNAMETAL 7090445 is a CNMG-style indexable turning insert designed for use in CNC and manual turning operations on metalcutting lathes. Built from carbide substrate with an AlTiN coating and KENNAMETAL KCU10B grade, this insert handles demanding interrupted and continuous cuts. The diamond-shaped insert (80-degree included angle) provides a strong cutting edge geometry suited for general turning applications. With a 3/8-inch inscribed circle and a 1/32-inch (0.0313-inch) corner radius, it delivers a balance of strength and finish quality across a range of workpiece materials. The neutral hand orientation allows fitment into standard CNMG toolholders without left- or right-hand restriction.

This insert is used in precision turning applications across aerospace, automotive, and general machining environments. The CNMG geometry is a widely adopted standard in production and job-shop turning cells. It is suited for shops running moderate to high stock-removal operations where consistent tool life and edge predictability are priorities. Licensed machinists and CNC operators working with steel, stainless, and other ferrous materials in production environments are the primary users of this insert style.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct insert clamp and seating screw torque as specified by the toolholder manufacturer. Inspect the insert pocket and clamp for debris or wear before seating a new insert to ensure proper edge registration.
