Kennametal 7093291 Dnmg Turning Insert Carbide Altin

Product Description

The KENNAMETAL 7093291 is a DNMG-style indexable turning insert designed for precision metal cutting on CNC lathes and manual turning centers. Built from carbide with an AlTiN (aluminum titanium nitride) coating, this insert carries the KCU10B grade designation and features a neutral hand orientation. The diamond insert shape provides a 55-degree included angle, and the MS chipbreaker geometry helps manage chip flow during turning operations. With four usable cutting edges per insert, this is a practical choice for shops focused on tooling cost per edge.

This insert is suited for turning operations in general-purpose and production machining environments, including finish and semi-finish passes on a range of workpiece materials. The AlTiN coating supports elevated cutting speeds and contributes to wear resistance in demanding applications. Licensed machinists and CNC operators working in job shops, production facilities, and aerospace or industrial component manufacturing are the primary users of this insert style.

Key Features

• DNMG insert style with 55-degree diamond shape for positive geometry turning
• KCU10B carbide grade with AlTiN coating for wear and heat resistance
• MS chipbreaker geometry for effective chip control during turning
• Four cutting edges per insert for extended tooling value
• Neutral hand orientation for flexible toolholder compatibility
• Inscribed circle of 0.5000 inches (12.70 mm) with corner radius of 0.0156 inches (0.40 mm)

Compatibility

Designed as an OEM-style indexable turning insert for DNMG-compatible toolholders accepting a 1/2-inch inscribed circle insert with N clearance and M tolerance codes.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is powered down and the turret or toolpost is locked before seating or indexing the insert. Use the appropriate torque wrench and clamping screw specified by the toolholder manufacturer to secure the insert. Never exceed recommended cutting parameters for the KCU10B grade as specified in the machining data for the target workpiece material.
