Sandvik Coromant 5756744 Turning Insert WNMG432-QM 235

Product Description

The SANDVIK COROMANT 5756744 is a WNMG432-QM 235 grade solid carbide turning insert designed for external turning operations on CNC lathes and turning centers. The insert features a dual-layer TiCN and TiN coating applied over a carbide substrate, providing wear resistance and edge durability during medium to finish turning. The trigon insert shape carries an 80-degree included angle and a 1/32-inch corner radius, making it well suited for profiling and contour turning. Insert thickness is 3/16 inches and inscribed circle diameter is 1/2 inch. This insert is installed by machinists and toolroom technicians in precision metal-cutting environments.

This turning insert is used in general-purpose metal-cutting applications including steel, alloy steel, and cast iron workpieces at medium cutting depths. The QM chip breaker geometry and 235 grade combination are suited for finishing and light-to-medium roughing passes where consistent chip control and surface finish are priorities. The WNMG style and N clearance code indicate a neutral-relief, mechanically clamped or pin-lock toolholder seating. Typical installations are in ISO-standard WNMG toolholders on production CNC turning equipment in job shop and manufacturing environments.

Compatibility

Designed for use in WNMG-style ISO-standard toolholders that accept a 1/2-inch inscribed circle insert with clamp or pin-lock holding. ISO code WNMG 08 04 08-QM 235 applies for toolholder cross-reference.

Installation Notes

Turning inserts of this type are seated and serviced by machinists or toolroom technicians on powered-down or E-stopped CNC turning equipment. Always index or replace inserts with the machine spindle locked and all axes at a safe position. Use the correct torque driver and seating pin specified by the toolholder manufacturer when clamping the insert. Inspect the insert pocket for debris or damage before seating a new insert to ensure proper support and accurate cutting geometry.
