Kennametal 7093278 Cnmg Turning Insert Carbide Altin

Product Description

The KENNAMETAL 7093278 is a CNMG-style indexable turning insert designed for CNC lathe and turning center applications. Made from carbide and finished with an AlTiN (aluminum titanium nitride) coating, it is built to handle demanding metal-cutting operations at elevated temperatures. The insert features an 80-degree diamond shape with a 3/64 inch (0.0169 inch decimal) corner radius and a neutral hand orientation. Grade KCU10B provides the substrate toughness and wear resistance needed for interrupted cuts and difficult-to-machine alloys. Licensed machinists and CNC operators typically specify this insert for roughing and semi-finishing passes on steel, stainless, and cast materials.

This insert is suited for external and internal turning, facing, and profiling operations on manual and CNC lathes in job shop, production, and maintenance machining environments. The CNMG geometry with RP chip breaker promotes controlled chip formation across a range of feed rates and depths of cut. With 8 cutting edges per insert, it offers a cost-effective indexing cycle for medium to high-volume turning work.

Key Features

• CNMG insert style with 80-degree diamond shape (Insert Shape Code: C)
• AlTiN coating for heat resistance and extended tool life in dry or minimal-coolant cutting
• Manufacturer Grade KCU10B carbide substrate for toughness in interrupted and continuous cuts
• 3/64 inch corner radius (0.0169 inch) for balanced edge strength and surface finish
• RP chip breaker geometry for controlled chip evacuation
• 8 indexable cutting edges per insert for maximum value per unit
• Neutral hand orientation for flexible toolholder compatibility

Compatibility

Designed as an OEM-style replacement insert for CNMG-style toolholders accepting a 3/4 inch inscribed circle, 1/4 inch thickness, and N clearance with M tolerance class. Confirm toolholder specifications before ordering.

Installation Notes

Indexable turning inserts are installed and replaced by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before indexing or replacing the insert. Use the correct torque wrench and clamp hardware specified by the toolholder manufacturer - do not overtighten or use improvised tools on the clamping screw. Inspect the seat and clamp for wear or damage each time the insert is indexed.
