Kennametal 7090450 Cnmg Turning Insert Altin Carbide

Product Description

The KENNAMETAL 7090450 is a CNMG-style indexable carbide turning insert designed for precision metal cutting on CNC lathes and turning centers. It features an 80-degree diamond insert shape, a 1/32 inch (0.0313 inch) corner radius, and an AlTiN coating applied over a KCU10B carbide grade substrate. The FF chip breaker geometry promotes controlled chip flow across a wide range of cutting conditions. With four usable cutting edges and a neutral hand orientation, this insert delivers consistent performance in production turning environments. Licensed machinists and CNC operators use this insert for general-purpose and interrupted-cut turning applications.

The 7090450 is suited for external turning operations on CNC lathes in both job shop and production settings. The CNMG form factor fits standard CNMG toolholders with matching clearance code N and tolerance code M. The 1/2 inch inscribed circle and 3/16 inch insert thickness place this insert in the mid-size range appropriate for medium-depth-of-cut operations. The KCU10B grade with AlTiN coating is positioned for cutting ferrous and nonferrous workpiece materials where heat resistance and edge wear are primary concerns.

Key Features

• CNMG insert style with 80-degree diamond shape for versatile turning geometry
• AlTiN coating on KCU10B carbide substrate for heat resistance and extended edge life
• FF chip breaker for controlled chip evacuation across varied feed and depth conditions
• Four cutting edges per insert to maximize tool utilization
• 1/32 inch corner radius for balanced edge strength and surface finish capability
• Neutral hand orientation compatible with standard CNMG toolholder setups

Compatibility

Designed as an OEM-style indexable insert for use in standard CNMG-style turning toolholders with clearance code N and tolerance code M seating geometry.

Installation Notes

Installation is performed by qualified CNC machinists or tool-room technicians. Power down and lock out the machine before indexing or replacing inserts. Use the correct torque wrench and clamp screw specified by the toolholder manufacturer to secure the insert - do not overtighten by hand estimation. Inspect the insert pocket for wear, debris, or damage before seating a new insert.
