Kennametal 7093477 Cnmg Turning Insert Altin Carbide

Product Description

The KENNAMETAL 7093477 is a CNMG-style indexable turning insert designed for precision metal cutting on CNC lathes and manual turning centers. Built from carbide substrate with an AlTiN (aluminum titanium nitride) coating, this insert carries the KCU10B manufacturer grade, which is suited for interrupted cuts and demanding turning applications. The diamond-shaped insert geometry features an 80-degree included angle and a 0.0313 inch (1/32 inch) corner radius, providing a strong cutting edge for general-purpose external and internal turning. Installation is neutral-hand, making it compatible with both right- and left-hand toolholders designed for CNMG geometry.

This insert fits standard CNMG toolholders used in production turning of steel, stainless steel, and similar materials. The MP chip breaker geometry is designed to manage chip flow at moderate feeds and depths of cut, reducing chip packing in the cut zone. It is commonly used in job shop and production environments where operators need a reliable general-purpose insert for roughing and semi-finishing passes. Machinists and CNC operators in metalworking shops are the primary installers of this insert style.

Key Features

• CNMG insert style with diamond shape and 80-degree included angle for strong edge geometry

• KCU10B grade optimized for interrupted and demanding turning operations
• MP chip breaker for controlled chip flow at moderate cutting parameters
• Neutral-hand orientation fits both right- and left-hand CNMG toolholders
• Four usable cutting edges per insert for cost-effective tool management

Compatibility

Designed as an OEM-style replacement insert for standard CNMG 432 toolholders accepting a 0.1875 inch insert thickness and 0.0313 inch corner radius with MP chip breaker geometry.

Installation Notes

Insert changes should be performed with the machine powered down and at a full stop. Use a proper torque wrench and insert clamp screw to seat the insert fully against the toolholder pocket — do not overtighten by hand alone. Verify insert seating and edge orientation before resuming cuts. Always wear appropriate PPE when handling carbide inserts, as edges are extremely sharp.
