Sandvik Coromant 5724051 Turning Insert CNMG431-WF 5015

Product Description

The SANDVIK COROMANT 5724051 is a solid carbide, uncoated turning insert in the CNMG431-WF 5015 designation, part of the T-Max P series. It features an 80-degree diamond insert shape (shape code C), a 0.5-inch inscribed circle, and a 1/64-inch (0.0156-inch) corner radius. The WF chip breaker geometry is designed for finishing operations, and the neutral hand orientation suits a wide range of turning setups. With four cutting edges and a clamp-and-pin holding method, this insert is suited for CNC lathe work performed by machinists and tool-and-die professionals in production environments.

This insert is engineered primarily for steel workpieces (ISO material code P) with cast iron as a secondary workpiece material (ISO material code K). It fits standard CNMG toolholders configured for the 431 insert size code. Typical applications include external turning, facing, and profiling on CNC lathes in light to medium finishing passes. The T-Max P series is a general-purpose turning platform suited for both high-volume production and job-shop use on ferrous materials.

Installation Notes

Turning insert installation should be performed by a qualified machinist with the machine fully powered down and the spindle locked before indexing or replacing inserts. Use the appropriate torque wrench and clamping hardware specified for the toolholder — do not overtighten the clamp screw. Inspect the insert pocket and seating surface for chips or debris before seating the new insert. Always verify insert orientation and chip breaker direction relative to the intended cut before resuming operation.
