Kennametal 7093851 Tcmt Turning Insert Altin Carbide

Product Description

The KENNAMETAL 7093851 is a TCMT-style triangular carbide turning insert designed for precision metal-cutting operations on CNC lathes and manual turning centers. Coated with AlTiN for heat and wear resistance, this insert carries a KCU10B manufacturer grade suited for demanding cutting conditions. The neutral hand orientation makes it compatible with a wide range of toolholders. With a 0.0313 inch corner radius and a 7-degree relief angle, it delivers controlled chip formation and consistent edge life across a variety of workpiece materials. Installation and replacement are handled by qualified machinists and CNC operators in production and job-shop environments.

This insert is used in external and internal turning applications where triangular insert geometry is specified. The TCMT designation indicates a triangular shape with a 7-degree relief angle, neutral hand, and a tolerance and chip-breaker configuration suited for finishing and light roughing passes. The LF chip breaker geometry promotes efficient chip evacuation at moderate feed rates. At 0.1875 inches thick and 0.1875 inches wide with three usable cutting edges, this insert provides cost-effective tool life per edge in high-volume turning operations on ferrous and non-ferrous metals.

Key Features

• AlTiN coating provides elevated heat resistance and extended tool life in dry or minimal-lubrication cutting
• KCU10B grade carbide substrate engineered for consistent performance in turning applications
• Triangular insert shape with 60-degree included angle delivers three usable cutting edges per insert
• 0.0313 inch corner radius balances surface finish quality with edge strength
• LF chip breaker geometry supports controlled chip formation at moderate feeds
• Neutral hand orientation fits a broad range of TCMT-compatible toolholders

Compatibility

Designed as a direct-fit replacement for TCMT-style toolholders accepting triangular inserts with a 3/16 inch thickness, C clearance code, M tolerance code, and size code 432. Consult your toolholder documentation to confirm insert size and seating compatibility before use.

Installation Notes

Insert replacement should be performed by a qualified machinist or CNC operator with the machine powered down and in a locked-out, tagged-out state per applicable safety procedures. Use the correct torque wrench and clamping screw specified by the toolholder manufacturer to seat the insert properly. Inspect the insert pocket and clamping hardware for wear or damage before installing a new insert. Do not use damaged or chipped inserts, as they can fracture during cutting and create a safety hazard.
