Sandvik Coromant 8019576 CNMG543-HM Turning Insert

Product Description

The SANDVIK COROMANT 8019576 is a carbide turning insert in the CNMG series, designed for external and internal turning operations on CNC lathes and turning centers. It carries a multi-layer CVD coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal stability across a range of cutting conditions. The insert features an HM chip breaker geometry and is classified at Grade 4425, making it suited for medium to semi-finishing operations. Installation requires either a clamp or screw holding method. This insert is typically mounted by a machinist or CNC operator following established tool change procedures.

This insert is appropriate for use in turning applications involving secondary workpiece materials classified under ISO code K, which corresponds to cast iron and similar materials. The ISO designation for this insert is CNMG 16 06 12-HM 4425. It fits standard CNMG-style toolholders and is a direct replacement insert for production and job shop environments where consistent surface finish and dimensional accuracy are required.

Key Features

• Multi-layer CVD coating: TiCN, Al2O3, and TiN for extended tool life and heat resistance
• HM chip breaker geometry for controlled chip formation in medium turning operations
• Neutral hand orientation for flexible toolholder compatibility
• Clamp or screw holding method for secure seating in standard CNMG toolholders
• Grade 4425 carbide substrate suited for medium to semi-finishing cuts
• ISO code CNMG 16 06 12-HM 4425 for straightforward cross-referencing

Compatibility

Designed as a direct-fit replacement for standard CNMG-style turning toolholders that accept a 5/8-inch inscribed circle insert with a 1/4-inch thickness and clamp or screw holding. ISO designation CNMG 16 06 12-HM 4425 may be used for cross-reference with compatible toolholder systems.

Installation Notes

Insert replacement should be performed by a qualified machinist or CNC operator with the spindle fully stopped and the machine in a locked-out, de-energized state per applicable lockout/tagout procedures. Seat the insert fully into the toolholder pocket before engaging the clamp or screw fastener. Inspect the toolholder pocket for wear or debris before seating a new insert. Do not exceed the insert holding method specifications of the toolholder.
