Kennametal 7093268 Tnmg Carbide Turning Insert Altin

Product Description

The KENNAMETAL 7093268 is a TNMG-style carbide turning insert designed for precision external turning operations on CNC and manual lathes. Built to grade KCU10B and coated with AlTiN (aluminum titanium nitride), this triangular insert delivers thermal resistance and wear protection across a range of cutting conditions. It features a 0.40 mm (1/64 inch) corner radius, a neutral hand orientation, and an MS chip breaker geometry suited for medium cutting applications. With six usable cutting edges per insert, it offers extended tool life per unit. This insert is installed by machinists and CNC operators in production and job-shop environments.

The 7093268 is intended for turning operations where a 60-degree included angle triangular insert is required. The TNMG insert style with MS chip breaker geometry is commonly applied in medium-duty turning of steel and similar materials. The AlTiN coating supports elevated cutting speeds and dry or minimal-coolant machining strategies. A 0.5000 inch (12.70 mm) inscribed circle and 0.1875 inch (4.76 mm) insert thickness confirm compatibility with standard TNMG toolholders sized for this insert geometry.

Key Features

• AlTiN coating provides high thermal resistance for elevated cutting speeds
• KCU10B carbide grade for wear resistance in medium turning applications
• MS chip breaker geometry for effective chip control in medium-duty cuts
• Six cutting edges per insert maximize yield per unit
• Neutral hand orientation fits standard TNMG right- and left-hand toolholders
• 0.40 mm corner radius minimizes edge stress on moderate finishing passes

Compatibility

Designed as an OEM-style replacement insert for standard TNMG toolholders accepting a 1/2 inch inscribed circle triangular insert with a 3/16 inch thickness and N clearance, M tolerance classification.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Power down and lock out the machine spindle before seating or indexing the insert. Use the correct torque wrench and insert screw specified by the toolholder manufacturer - do not overtighten the clamping screw. Inspect the toolholder pocket and seating surface for chips or damage before each insert change to ensure proper seating and runout.
