Sandvik Coromant 5756094 VNMG332-MM 2025 Turning Insert

Product Description

The SANDVIK COROMANT 5756094 is a VNMG-style diamond turning insert in the T-Max P series, designed for precision metal turning on CNC lathes and turning centers. It carries grade 2025 solid carbide substrate with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, a combination engineered for wear resistance and thermal stability at elevated cutting speeds. The insert is neutral-hand, features a 35-degree included angle, a 3/8-inch inscribed circle, and a 0.0313-inch corner radius with the MM chip breaker geometry. It is installed by machinists and CNC operators in production and job-shop environments.

This insert is optimized for turning stainless steel (ISO material group M), where the CVD multilayer coating controls built-up edge and crater wear. The MM chip breaker geometry is suited for medium finishing and light roughing passes, providing reliable chip control across a range of feed rates and depths of cut. Each package contains one insert. The minimum order quantity is 10 inserts. With 4 usable cutting edges per insert, the 5756094 delivers consistent indexable performance across high-volume stainless steel turning applications.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for thermal and abrasion resistance
• Grade 2025 carbide substrate optimized for stainless steel (ISO M) turning
• MM chip breaker geometry for medium finishing to light roughing
• 4 cutting edges per insert for extended tool life and lower cost per edge
• Neutral hand orientation for flexible toolholder compatibility
• Clamp and pin insert holding method for secure, repeatable seating

Compatibility

Designed for use in VNMG-style toolholders accepting a 3/8-inch inscribed circle, 3/16-inch thick insert with a 0.150-inch hole diameter and clamp or pin retention. ISO designation VNMG 16 04 08-MM 2025. Verify toolholder pocket geometry and clamping method before installation.

Installation Notes

Installation is performed by a machinist or CNC operator. Power down and lock out the machine spindle before indexing or replacing the insert. Use the appropriate torque wrench and clamping hardware specified by the toolholder manufacturer — do not over-torque the clamp screw. Inspect the insert pocket and seating surface for chips or debris before seating the new insert to ensure accurate and secure positioning.
