Sandvik Coromant 5756640 WNMG433-QM 1105 Turning Insert

Product Description

The SANDVIK COROMANT 5756640 is a WNMG433-QM 1105 grade solid carbide turning insert designed for external turning operations on CNC lathes and turning centers. Part of the T-Max P series, this insert features a TiAlN2 coating applied via PVD process, delivering wear resistance and thermal stability in demanding metal-removal applications. The trigon (W) insert shape provides an 80-degree included angle with six available cutting edges, offering good economy per edge. With a 0.5000-inch inscribed circle and a corner radius of 0.0472 inches (3/64 inches), this insert is suited for medium to semi-finish turning passes.

This insert is intended for turning of steel as the primary workpiece material, with secondary suitability for stainless steel, superalloys, and titanium. The QM chip breaker geometry is engineered to control chip flow across a range of depths of cut up to 0.2949 inches (7.49 mm), making it applicable in both production turning and job shop environments. It is installed using a clamp and pin holding method and is held to M tolerance with N clearance. Licensed machinists and CNC operators in metalworking shops are the typical users of this insert.

Key Features

• TiAlN2 PVD coating for heat and wear resistance in steel turning
• QM chip breaker geometry supports chip control across a wide depth-of-cut range
• Six cutting edges per insert for extended tool economy
• Neutral hand orientation for flexible application on standard toolholders
• Clamp and pin holding method for secure, repeatable seating
• ISO code WNMG 08 04 12-QM 1105 for cross-reference with compatible tooling systems

Compatibility

Designed for use in T-Max P series toolholders accepting WNMG style inserts with a 0.2032-inch hole diameter. Compatible workpiece materials include steel, stainless steel, superalloys, and titanium per the supplier specification. ISO insert size code 0804 applies.

Installation Notes

Installation is performed by a qualified CNC machinist or toolroom technician. Before changing inserts, the machine must be powered down and the spindle confirmed stopped. Seat the insert fully against the pocket locating surfaces before tightening the clamp to ensure proper support and to avoid insert rocking. Index only to clean, undamaged cutting edges, and inspect the toolholder pocket for wear or debris before each insert change.
