Sandvik Coromant 5756002 Turning Insert VNGA331S0330A 7025

Product Description

The SANDVIK COROMANT 5756002 is a solid carbide, uncoated turning insert in the VNGA style, designed for precision turning of hard materials in metal-cutting operations. This insert carries the manufacturer grade 7025 and belongs to the T-Max P series, a platform widely used in external turning and profiling applications. The 35-degree diamond shape (Insert Shape Code V) delivers a sharp, acute cutting geometry suited to contour turning and finish passes on hardened workpieces. With a neutral hand orientation and four available cutting edges, it offers efficient tool life and consistent performance. Licensed machinists and CNC operators working in production turning environments are the primary users.

This insert is intended for turning hard materials, designated by primary workpiece material code H, making it appropriate for hardened steels and similar demanding workpiece materials. The T-Max P series is a common platform for ISO-style external turning toolholders, and this insert fits into that system using a clamp and pin holding method. It is suited for both high-volume production turning and precision finishing passes where tight tolerances and surface finish consistency are required on CNC lathes and turning centers.

Key Features

• Solid carbide construction, grade 7025, uncoated bright finish for hard-material turning
• 35-degree diamond insert shape (VNGA style) with 4 cutting edges for maximized tool life
• Corner radius of 0.0156 inches (1/64 inch) for fine contour and finish turning
• Neutral hand orientation for flexible toolholder compatibility
• Chip breaker code A for controlled chip formation in hard-material applications
• Clamp and pin holding method for secure seating in compatible toolholders

Compatibility

Designed for use in VNGA-style ISO turning toolholders within the T-Max P series platform. ISO code reference: VNGA160404S01030A 7025. Consult toolholder documentation to confirm pocket geometry, clearance code N, and tolerance code G compatibility before installation.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC tooling technician with the machine fully powered down and the spindle locked. Use the correct torque driver or clamping tool specified for the T-Max P toolholder to seat the insert securely via the clamp and pin system. Inspect the insert pocket for debris or wear before seating a new insert. Never force an insert into a pocket with mismatched geometry, as this can cause insert fracture or toolholder damage.
