Sandvik Coromant 5756345 Turning Insert WNMG332-MM 2015

Product Description

The SANDVIK COROMANT 5756345 is a WNMG332-MM 2015 grade solid carbide turning insert designed for precision metal cutting on CNC lathes and turning centers. It features a multi-layer TiCN, Al2O3, and TiN CVD coating that provides wear resistance, thermal protection, and built-in edge lubricity. The 80-degree trigon (W) shape with a neutral 0-degree relief angle suits a wide range of turning operations including general external and internal profiling. With a 1/32-inch corner radius and a 3/8-inch inscribed circle, this insert delivers consistent chip control through the MM chip breaker geometry. Installed by machinists and tooling technicians, it seats in compatible WNMG-style toolholders secured by clamp or pin holding methods.

This insert is suited for medium to finish turning applications on steel and other machinable alloys where coating performance and dimensional consistency are critical. The ISO designation WNMG 06 04 08-MM 2015 confirms compatibility with standard WNMG toolholder pockets used across production turning operations in job shops and manufacturing facilities. The G-type chip breaker geometry promotes reliable chip evacuation at moderate feed rates, reducing cycle interruptions during continuous cuts. Sold individually per package; minimum order quantity is 10 pieces.

Key Features

• Multi-layer TiCN, Al2O3, and TiN coating for wear resistance and thermal stability
• 80-degree trigon insert shape (W) with 0-degree relief angle for versatile turning profiles
• 1/32-inch (0.0313 inches) corner radius for controlled surface finish
• MM chip breaker geometry (G-type) for reliable chip evacuation at moderate feeds
• Clamp and pin holding method compatible with standard WNMG toolholder systems
• ISO grade 2015 carbide substrate engineered for consistent tool life in production environments

Compatibility

Designed for use in WNMG-style toolholders that accept clamp or pin insert retention. ISO designation WNMG 06 04 08-MM 2015 applies. Compatible toolholder pockets must match the W insert shape, M tolerance, N clearance, and 3/8-inch inscribed circle specification.

Installation Notes

Installation is performed by qualified machinists or tooling technicians following standard CNC lathe lockout and de-energization procedures before any insert change. Ensure the toolholder pocket and seating surfaces are clean and free of debris before seating the insert. Use the correct clamp screw torque as specified by the toolholder manufacturer — do not rely on values not provided in the insert documentation. Verify insert orientation and seating before resuming spindle operation.
