Sandvik Coromant 5755202 Turning Insert TRDC1308F 2025

Product Description

The SANDVIK COROMANT 5755202 is a solid carbide turning insert in the CoroTurn TR series, designed for precision external and internal turning operations. It carries the ISO designation TRDC1308F2025 and features a multilayer MTCVD-applied coating of TiCN, Al2O3, and TiN for extended wear resistance and thermal protection. The insert is 13 mm long with a 13 mm inscribed circle, a 0.79 mm (1/32 inch) corner radius, and a 60-degree diamond shape. With manufacturer grade 2025, this insert is optimized for turning stainless steel and other ISO M workpiece materials. Licensed machinists and CNC operators install this insert in compatible CoroTurn TR toolholders for production and job-shop turning applications.

This insert suits finishing and semi-finishing operations on stainless steel workpieces in both light manufacturing and production environments. The F chip breaker geometry supports controlled chip formation at moderate depths of cut, with a maximum depth of cut of 12.20 mm (0.4803 inches). It is secured by screw clamping in CoroTurn TR compatible toolholders. The neutral hand orientation makes it suitable for a range of standard turning setups on CNC lathes and turning centers.

Installation Notes

This insert is installed and indexed by a licensed machinist or CNC operator. Power down and lock out the machine spindle before changing inserts. Use the correct Torx or hex key for the clamping screw as specified by the toolholder manufacturer, and never reuse a visibly chipped or worn cutting edge. Verify insert seating and screw torque before resuming cutting operations.
