Sandvik Coromant 8019566 Turning Insert Tpmr 11 03 08-53 4425

Product Description

The SANDVIK COROMANT 8019566 is a TPMR-style solid carbide turning insert designed for precision metal cutting on CNC lathes and turning centers. Carrying the ISO designation TPMR 11 03 08-53 4425, this insert features a triangular shape (Shape Code T), a neutral hand orientation, and a CVD-applied multilayer coating of TiCN, Al2O3, and TiN. The 4425 grade designation targets steel cutting applications. With a 0.25 inch inscribed circle and a 0.0313 inch corner radius, it is built for light-to-medium finishing and semi-finishing passes. This insert is installed by machinists and CNC toolroom technicians working in production and job-shop environments.

This insert is suited for turning steel workpieces in both production and job-shop settings. The primary workpiece material designation is steel, with a secondary material code of K, indicating suitability for cast iron as well. The 53 chip breaker geometry supports controlled chip evacuation during continuous turning operations on CNC lathes. The clamp-style holding method and P clearance angle with M tolerance class make this insert compatible with standard TPMR toolholders used in a wide range of turning applications.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for wear resistance and thermal protection
• 4425 grade carbide substrate optimized for steel cutting
• Neutral hand orientation for use in both left- and right-hand toolholder setups
• 53 chip breaker geometry for controlled chip formation during continuous turning
• Clamp-style insert holding with P clearance and M tolerance for secure, repeatable seating
• 0.0313 inch corner radius suitable for light finishing and semi-finishing operations

Compatibility

Designed for use with standard TPMR-series toolholders. ISO code TPMR 11 03 08-53 4425 confirms fitment with holders specified for the TPMR insert style, P clearance angle, M tolerance, and 1/4 inch inscribed circle geometry.

Installation Notes

Installation should be performed by qualified machinists following the toolholder manufacturer torque and clamping procedures for TPMR clamp-style inserts. Ensure the machine spindle is fully stopped and the turret is locked before seating or removing the insert. Inspect the insert pocket and shim for damage or debris before installing a new insert. Do not exceed the recommended depth of cut or feed rate for the 4425 grade as specified in the cutting data tables for the target workpiece material.
