Sandvik Coromant 8019528 Turning Insert Rcmt 09 T3 00-M0 4425

Product Description

The SANDVIK COROMANT 8019528 is a round turning insert in the RCMT-M0 (INCH) series, designed for external and internal turning operations on CNC lathes and turning centers. The insert carries ISO designation RCMT 09 T3 00-M0 4425 and is manufactured from solid carbide with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN. This coating stack provides wear resistance and thermal stability for productive cuts in steel. The insert features a neutral hand orientation, a 0.375 inch inscribed circle, and a 0.1875 inch corner radius. It is held in the toolholder by clamp and screw and is installed by machinists and toolroom technicians in production turning applications.

This insert is suited for turning steel workpieces in light to medium roughing and finishing applications. The M0 chip breaker geometry supports controlled chip formation across a range of depths of cut and feed rates in steel. Secondary workpiece material capability is also noted under ISO material group K. Typical environments include CNC production turning, job shop lathes, and maintenance-shop turning centers where consistent tool life and predictable performance on steel are priorities.

Key Features

• CVD multilayer coating: TiCN plus Al2O3 plus TiN for wear resistance and heat management in steel cutting
• Round insert shape (code R) with 0.1875 inch corner radius for smooth surface finish and strong cutting edge
• Manufacturer grade 4425 optimized primarily for steel (ISO P) with secondary capability in ISO K materials
• M0 chip breaker geometry for controlled chip evacuation in light to medium turning operations
• Clamp and screw holding method provides secure seating in compatible RCMT-style toolholders
• Neutral hand orientation for flexible use in both right-hand and left-hand turning setups

Compatibility

Designed for use in RCMT-style toolholders that accept a 0.375 inch inscribed circle round insert with a 7-degree relief angle (clearance code C, tolerance code M). Consult the toolholder manufacturer specifications to confirm fit before installation.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and de-energize the machine spindle, and lock out the machine before changing inserts. Use the correct torque wrench and clamp screw as specified by the toolholder manufacturer when seating the insert. Inspect the insert seat and toolholder pocket for damage or debris before installing a new insert to ensure proper seating and edge engagement.
