Sandvik Coromant 5766744 Turning Insert CNGA432S0835A 7025

Product Description

The SANDVIK COROMANT 5766744 is a solid carbide, uncoated turning insert designed for precision metal cutting on CNC lathes and turning centers. Manufactured to CNGA insert style with an 80-degree diamond shape and a neutral hand orientation, this insert carries the manufacturer grade 7025 and belongs to the T-Max P series. It features a 0.5000-inch inscribed circle, a 1/32-inch (0.0313-inch) corner radius, and an insert thickness of 3/16 inch (0.1875 inch). With four cutting edges available per insert, it is optimized for machining hard workpiece materials, making it a productive choice for shops running tight-tolerance turning operations. Licensed machinists and CNC operators handling hardened steels and similar difficult alloys are the primary users of this insert.

This insert is suited for applications involving hard materials where uncoated solid carbide provides the rigidity and edge sharpness required. The T-Max P series is a recognized platform for external turning operations in both roughing and finishing passes, depending on depth of cut and feed parameters. The CNGA120408S02035A 7025 ISO code confirms its dimensional and grade classification. Typical install environments include production turning cells and job shops running ferrous hard-turned components. The chip breaker designation A contributes to predictable chip control at the cutting edge during interrupted or continuous hard-turning cuts.

Key Features

Compatibility

Designed as a T-Max P series OEM-style turning insert for use in compatible SANDVIK COROMANT toolholders accepting CNGA-style inserts with a 0.2030-inch hole diameter and insert size code 432. Verify toolholder pocket specifications before installation to confirm proper fit and clamping engagement.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Power down and lock out the machine spindle before seating or changing inserts. Use the appropriate torque wrench and insert key specified by the toolholder manufacturer when tightening clamp screws — do not exceed the torque value listed in the toolholder documentation. Inspect the insert pocket and locating surfaces for chips or debris before seating the insert to ensure correct indexing and prevent premature edge failure.
