Tungaloy 6796302 CNMG432SM Turning Insert AH6225 Carbide

Product Description

The TUNGALOY 6796302 is a solid carbide turning insert in the CNMG-SM series, designed for external turning, facing, and boring operations on steel and stainless steel workpieces. It carries an ANSI insert code of CNMG432 and an ISO code of CNMG120408-SM. The insert is coated with a multilayer TiAlN and TiCN PVD coating under the AH6225 grade, which balances moderate wear resistance with toughness across roughing and medium machining applications. With a 0.5-inch inscribed circle and a 0.031-inch corner radius, this insert suits a range of material removal tasks where consistent edge life is critical. Licensed machinists and CNC tooling technicians are the primary users.

This insert is suited for use in CNC turning centers and manual lathes handling steel (ISO P) and stainless steel (ISO M) workpieces. It targets ISO material grade classifications P20, P30, M20, and M30, making it appropriate for both moderate and higher wear-resistance demands. The SM chip breaker geometry is optimized for roughing and medium machining cuts, and the negative rake and negative side clearance design supports stable cutting forces. The insert accommodates clamp or pin holding methods, fitting standard CNMG-style toolholders.

Key Features

• AH6225 PVD multilayer TiAlN and TiCN coating for extended tool life on steel and stainless steel
• 80-degree diamond (rhombic) insert shape with 4 usable cutting edges
• SM chip breaker geometry supports roughing and medium machining operations
• Negative rake angle of -10 degrees with chamfered and honed cutting edge style for edge stability
• Maximum depth of cut of 0.1575 inches suitable for aggressive material removal
• Compatible with both clamp and pin insert holding methods

Compatibility

Designed as an OEM-style replacement or direct-fit insert for standard CNMG-style toolholders accepting a CNMG432 (CNMG120408) insert geometry with clamp or pin holding. Meets ANSI and ISO standards for this insert family.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. Power down and lock out the machine spindle before seating or indexing the insert. Ensure the toolholder pocket and seating surfaces are free of chips and debris before clamping. Follow the toolholder manufacturer torque and clamping specifications for the specific clamp or pin style in use.
