Sandvik Coromant 7231332 Turning Insert CNMG433-MM 2220

Product Description

The SANDVIK COROMANT 7231332 is a CNMG433-MM 2220 series turning insert designed for precision external turning operations in CNC lathe and turning center applications. This solid carbide insert features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, delivering wear resistance and thermal stability across a range of cutting conditions. The insert carries an 80-degree diamond shape (C), a neutral hand orientation, a 0.5000-inch inscribed circle, and a corner radius of 0.0469 inches (3/64 inches). With four available cutting edges and an MM chip breaker geometry, it is engineered specifically for work on stainless steel and other ISO M-class workpiece materials. Licensed machinists, CNC operators, and toolroom technicians typically specify this insert for finishing and semi-finishing passes.

This insert is suited for ISO M-class stainless steel turning applications where consistent chip control and edge life are priorities. The MM chip breaker geometry is optimized for the work-hardening tendencies and gummy cutting behavior common in austenitic and duplex stainless steels. It fits standard CNMG-style toolholders with clamp and pin holding methods. Typical use scenarios include shaft turning, facing, and contour operations on CNC turning equipment in job shops and production environments.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for thermal and abrasion resistance
• MM chip breaker geometry optimized for ISO M-class stainless steel materials
• 80-degree diamond insert shape (C) with neutral hand orientation
• Four cutting edges per insert for extended tool economy
• Clamp and pin holding method compatible with standard CNMG toolholders
• Part of the SANDVIK COROMANT T-Max P series for external turning

Compatibility

Designed for use in standard CNMG433-style toolholders that accept clamp and pin holding. Compatible with T-Max P series turning systems. Confirm toolholder seat geometry and clamping configuration before installation.

Installation Notes

Insert replacement should be performed by a qualified machinist or CNC toolroom technician with the machine in a safe, powered-down state and all spindle rotation stopped. Use the appropriate torque wrench and insert-mounting hardware specified by the toolholder manufacturer when seating the insert. Inspect the insert pocket and clamping components for wear or debris before fitting a new insert. Never attempt to index or replace an insert while the machine is in cycle or the turret is in motion.
