Sandvik Coromant 5756761 WNMG432-QM 1105 Turning Insert

Product Description

The SANDVIK COROMANT 5756761 is a WNMG432-QM 1105 trigon turning insert designed for external turning operations on CNC lathes and turning centers. It features a solid carbide substrate with a PVD-applied TiAlN coating that provides thermal resistance and wear protection during interrupted and continuous cuts. The insert carries an 80-degree included angle, a 1/2-inch inscribed circle (0.5000 inches), and a 1/32-inch corner radius (0.0313 inches). With six cutting edges and a neutral hand orientation, it offers extended tool life and consistent chip control across a range of metal-cutting applications. Machinists and CNC operators install this insert in compatible WNMG-style toolholders.

This insert is optimized for primary use on steel (ISO material code P) and is also rated for stainless steel, superalloys, and titanium (ISO codes M, S). The QM chip breaker geometry is suited to medium machining conditions where reliable chip breaking and edge stability are required. It is a standard production insert used in job shops, aerospace component machining, and general metalworking environments. The ISO designation is WNMG 08 04 08-QM 1105, and the insert size code is 0804. Typical users are CNC machinists, toolroom technicians, and production turn operators.

Key Features

• PVD TiAlN coating for heat resistance and extended wear life in steel cutting
• QM chip breaker geometry for effective chip control in medium turning conditions
• Six usable cutting edges per insert for maximized value per unit
• Neutral hand orientation compatible with standard WNMG right-hand and left-hand toolholders
• 80-degree trigon insert shape provides a strong cutting edge and good clearance
• 1/32-inch corner radius balances surface finish quality with edge strength

Compatibility

Designed for use in WNMG432-style insert pockets within the SANDVIK COROMANT T-Max P turning toolholder series. Compatible insert holding methods include clamp and pin style. Insert shape code is W; clearance code N; tolerance code M. Verify toolholder pocket specifications before installation.

Installation Notes

This insert is installed and replaced by CNC machinists or toolroom technicians as part of routine indexable insert maintenance. Power down and lock out the machine spindle before accessing the toolholder. Use the appropriate torx or hex key torque wrench as specified by the toolholder manufacturer when seating the clamping screw. Inspect the insert pocket and seating surface for chips or debris before installing a fresh edge to ensure proper seating and dimensional accuracy.
