Sandvik Coromant 8019555 Turning Insert Tpmr 09 02 08 4425

Product Description

The SANDVIK COROMANT 8019555 is a solid carbide turning insert in the TPMR series, designed for external turning operations on CNC lathes and turning centers. The insert carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which delivers wear resistance across the cutting zone and thermal protection at the rake face. The triangular insert shape (Shape Code T) with an 11-degree relief angle (Clearance Code P) and neutral hand orientation makes it a direct fit for standard TPMR-style clamp toolholders. With a 0.2188-inch inscribed circle and a 0.0313-inch corner radius, this insert is suited for medium-duty finishing and semi-finishing passes on steel workpieces. Machining professionals and CNC operators working in production turning environments are the primary users.

This insert is intended for turning steel as the primary workpiece material, with secondary suitability for cast iron and related ferrous materials per the K-code designation. It is used in production and job-shop turning environments where consistent surface finish and tool life on steel components are required. The TPMR 09 02 08 4425 ISO code identifies the insert geometry precisely, allowing direct cross-reference when specifying tooling for a job. Chip Breaker designation 53 is engineered for controlled chip formation during medium-depth passes. This insert is sold individually with a minimum order quantity of 10 units.

Compatibility

Designed for use in TPMR-style clamp toolholders that accept a triangular carbide insert with a 0.2188-inch inscribed circle and Tolerance Code M, Clearance Code P geometry. Confirm toolholder insert pocket specifications before installation.

Installation Notes

Insert installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or replacing inserts. Use the correct torque wrench and clamp screw specified by the toolholder manufacturer — do not overtighten, as this can fracture the carbide insert. Inspect the insert pocket for debris or wear before seating a new insert to ensure proper contact and repeatability.
