Tungaloy 6772177 Turning Insert Cnmg 432 Tm T9215

Product Description

The TUNGALOY 6772177 is a CNMG 432 TM indexable turning insert manufactured from solid carbide and finished with a multilayer CVD coating consisting of TiCN, Al2O3, and TiN. This coating sequence delivers thermal resistance and wear protection suited to continuous and interrupted cuts on ferrous materials. The insert carries the T9215 manufacturer grade, features an 80-degree diamond shape with a negative rake angle of -6 degrees, and provides four usable cutting edges per insert. It is sized at 0.508 inches in length with a 0.5-inch inscribed circle and a 0.0315-inch corner radius. Machinists and CNC turning professionals install this insert in compatible toolholders for production turning, facing, and boring operations.

This insert is intended for turning, facing, and boring applications on steel, stainless steel, and cast iron workpieces, corresponding to ISO material codes P, M, and K. It is well suited to P10 and P20 material grade applications. The TM chip breaker geometry controls chip flow across a range of depths of cut up to 0.1969 inches, making it appropriate for both light and moderate material removal rates in CNC lathe environments common to job shops and production machining facilities.

Key Features

• Multilayer CVD coating: TiCN, Al2O3, and TiN for wear and heat resistance
• T9215 carbide grade rated for steel, stainless steel, and cast iron (ISO P, M, K)
• 80-degree diamond insert shape with negative rake for strong cutting edge
• Four cutting edges per insert for extended tooling economy
• TM chip breaker compatible with turning, facing, and boring operations
• Clamp and pin insert holding method for secure, repeatable seating

Compatibility

Designed for use in CNMG-style toolholders that accept a 432-size insert with clamp or pin holding. Compatible with turning operations on steel, stainless steel, and cast iron per ISO workpiece codes P, M, and K. Conforms to ANSI and ISO insert standards for the CNMG 432 TM designation.

Installation Notes

This insert is installed by a qualified machinist or CNC turning technician. Power down and lock out the machine before indexing or replacing inserts. Use the appropriate torque wrench and manufacturer-specified clamping hardware for the toolholder; do not over-torque the clamp screw, as this can fracture the insert. Inspect the toolholder pocket and seating surfaces for wear or debris before mounting a new insert.
