Sandvik Coromant 7231476 Turning Insert TRDC1304-F 2220

Product Description

The SANDVIK COROMANT 7231476 is a solid carbide turning insert in the CoroTurn TR series, designed for precision external and internal turning operations. The insert carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal stability during cutting. It features a 60-degree diamond shape (Insert Shape Code T), a neutral hand orientation, and a corner radius of 0.0156 inches (0.40 mm). With an inscribed circle of 11.00 mm (0.4331 inches) and two cutting edges, this insert is suited for machining stainless steel and similar challenging workpiece materials. It is installed via screw clamping and includes an F chip breaker geometry.

This insert is intended for use in CNC turning centers and manual lathes where stainless steel (ISO material group M) is the primary workpiece material. The CoroTurn TR series is engineered for stable, predictable turning performance in demanding applications. The F chip breaker geometry supports controlled chip formation at moderate depths of cut and feed rates. Typical users include CNC machinists, tool-and-die technicians, and precision turning specialists working in production or job-shop environments.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before changing inserts. Use the appropriate torx or hex key to tighten the clamping screw to the toolholder manufacturer's specified torque; do not over-torque, as this can fracture the carbide insert. Inspect the insert pocket and clamping screw for debris or wear before seating the new insert.
