Sandvik Coromant 5723927 Turning Insert CNMG432-KM 3210

Product Description

The SANDVIK COROMANT 5723927 is a CNMG-style indexable turning insert from the T-Max P series, designed for external and internal turning operations on CNC lathes. The insert is manufactured from solid carbide substrate with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal stability during continuous or interrupted cuts. It carries an 80-degree diamond shape, a neutral hand orientation, and a KM chip breaker geometry. With four cutting edges per insert and a 1/32-inch corner radius, it delivers consistent performance across medium to heavy stock removal passes. Licensed HVAC, plumbing, and electrical trades aside, this insert is installed by CNC machinists and toolroom technicians.

The 5723927 is engineered primarily for turning cast iron workpieces, corresponding to ISO material group K. The KM chip breaker geometry is suited for medium cutting depths and feeds where chip control on gray and ductile cast iron is a priority. The T-Max P series is a common platform in production turning environments, fitting standard CNMG toolholders used on manual and CNC turning centers in both job shops and high-volume manufacturing facilities. The neutral hand designation makes it compatible with both left- and right-hand toolholder configurations.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for improved wear and heat resistance
• 80-degree diamond insert shape with neutral hand orientation
• KM chip breaker geometry optimized for cast iron turning
• Four usable cutting edges per insert for extended tooling economy
• 1/32-inch corner radius for medium-duty finishing and roughing
• T-Max P series platform for broad toolholder compatibility

Compatibility

Designed as an OEM-style indexable insert for standard CNMG toolholders accepting a 1/2-inch inscribed circle insert with clamp and pin holding method. Compatible model and system information beyond the T-Max P series designation was not specified in the available product data.

Installation Notes

Insert seating and clamping should be performed with the machine spindle at a full stop and all power isolated per shop lockout/tagout procedures. Verify the toolholder pocket and seating surfaces are free of chips and debris before indexing to a fresh cutting edge. Use the appropriate torque wrench and manufacturer-specified fastener when securing the clamp or pin to avoid insert cracking. Discard inserts that show chipping, cratering, or flank wear beyond acceptable limits rather than continuing to cut.
