Sandvik Coromant 5755711 Turning Insert VBMT332-MM 1125

Product Description

The SANDVIK COROMANT 5755711 is a VBMT332-MM 1125 grade solid carbide turning insert designed for external turning operations on CNC lathes and turning centers. It features a 35-degree diamond insert shape (V-style) with a 0.0313-inch corner radius and a PVD-applied dual-layer TiAlN and AlCr2O3 coating that supports cutting in steel, stainless steel, superalloy, and titanium workpieces. The MM chip breaker geometry promotes controlled chip formation across a wide range of feed rates. With a neutral hand orientation and screw-type clamping, this insert is compatible with standard VBMT toolholders used in production and job-shop turning environments.

This insert is part of the CoroTurn 107 series, engineered primarily for external turning of steel (ISO P) workpieces and secondarily rated for stainless steel (ISO M), superalloys (ISO S), and titanium (ISO S). It is suited for light to medium roughing and finishing passes in both residential machine-shop and industrial production settings. Licensed machinists and CNC operators install and index this insert. The ISO designation is VBMT 16 04 08-MM 1125. Each package contains one insert; the minimum order quantity is 10 inserts.

Key Features

• PVD-coated TiAlN and AlCr2O3 dual-layer coating for wear resistance on steel and high-temp alloys
• 35-degree diamond (V) insert shape with 5-degree relief angle for clearance in tight-profile turning
• MM chip breaker geometry for consistent chip control across varied feed and depth conditions
• Neutral hand orientation fits standard left- and right-hand VBMT screw-clamp toolholders
• Two cutting edges per insert; screw-type insert holding method for secure, repeatable indexing
• ISO grade 1125 carbide substrate rated for primary steel cutting with multi-material secondary capability

Compatibility

Designed for use in VBMT-style screw-clamp turning toolholders within the CoroTurn 107 series system. Primary workpiece material is steel (ISO P code); secondary workpiece materials include stainless steel, superalloy, and titanium (ISO M, P, and S codes). ISO insert designation VBMT 16 04 08-MM 1125.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct Torx or hex key specified by the toolholder manufacturer to secure the clamping screw - do not overtighten or use impact drivers. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert to ensure proper edge registration.
