Sandvik Coromant 8019556 Turning Insert Tpmr Carbide

Product Description

The SANDVIK COROMANT 8019556 is a solid carbide turning insert designated by ISO code TPMR 11 03 08 4425. It carries a multi-layer CVD coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal stability during continuous and interrupted steel cutting operations. The insert features a triangular shape (shape code T), a neutral hand orientation, and a 0.0313 inch corner radius. With a 0.2500 inch (1/4 inch) inscribed circle and a 0.1250 inch (1/8 inch) thickness, this insert is sized for medium-duty turning applications. It is held by clamp (holding method: clamp), with clearance code P and tolerance code M. Manufacturer grade is 4425.

This insert is engineered primarily for machining steel workpieces, with a secondary material classification of code K (cast iron family). It is suited for use in CNC lathes and manual turning centers where consistent surface finish and extended tool life on ferrous materials are required. The TPMR series geometry and chip breaker designation 53 make it appropriate for a range of depth-of-cut and feed combinations typical in production turning environments. Machinists, tool-and-die professionals, and CNC operators in job shops and production facilities are the primary installers and users of this insert.

Key Features

• CVD-applied multi-layer coating: TiCN, Al2O3, and TiN for extended wear life on steel
• Triangular insert shape (code T) with TPMR geometry and neutral hand for flexible toolholder compatibility
• 0.0313 inch corner radius for balanced edge strength and surface finish performance
• 0.2500 inch inscribed circle and 0.1250 inch thickness in the TPMR 11 03 08 series
• Clamp-style holding method with clearance code P and tolerance code M for secure, repeatable seating
• Chip breaker designation 53 suited for steel turning across moderate feed and depth-of-cut ranges

Compatibility

Designed as an OEM-grade replacement turning insert for TPMR-style toolholders accepting a triangular insert with a 0.2500 inch inscribed circle, clearance code P, and tolerance code M. Primary workpiece material compatibility is steel; secondary compatibility is cast iron (code K).

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Before changing inserts, ensure the machine spindle is fully stopped and all power or program execution is interrupted. Seat the insert firmly against the toolholder pocket walls before tightening the clamp to avoid insert movement or chipping during initial cuts. Inspect the insert pocket and clamp for wear or damage each time an insert is replaced.
