Sandvik Coromant 5724730 Turning Insert CNMG434-QM 1105

Product Description

The SANDVIK COROMANT 5724730 is a CNMG434-QM 1105 grade solid carbide turning insert designed for external turning operations on CNC lathes and turning centers. Coated with TiAlN via a PVD process, this insert delivers thermal and wear resistance suited to demanding cutting conditions. It features an 80-degree diamond insert shape, a 1/2-inch inscribed circle, and a 1/16-inch corner radius. The QM chip breaker geometry is engineered to control chip flow and reduce cutting forces across a range of depths of cut and feed rates. Four cutting edges are available per insert, and the neutral hand designation makes it adaptable to both left- and right-hand tool holders.

This insert is primarily rated for steel cutting applications and is secondarily suited for stainless steel, superalloys, and titanium workpiece materials. It belongs to the SANDVIK COROMANT T-Max P series, a line developed for productive turning in ISO P, M, and S material categories. Typical installation scenarios include production turning on CNC equipment where consistent edge life and chip control are required. The insert seats using a clamp and pin holding method, compatible with standard CNMG-style tool holders used in industrial machining environments.

Key Features

• TiAlN coating applied via PVD process for wear and thermal resistance
• 80-degree diamond insert shape with neutral hand orientation
• QM chip breaker geometry for effective chip control across varied feed and depth conditions
• Four usable cutting edges per insert
• 1/16-inch corner radius for balanced edge strength and surface finish
• Clamp and pin holding method for secure seating in CNMG-compatible tool holders

Compatibility

Designed for use in CNMG-style turning tool holders that accept a 434 insert size. Compatible with SANDVIK COROMANT T-Max P series tooling systems. Suitable for primary use on steel workpieces and secondary use on stainless steel, superalloys, and titanium per the manufacturer material classification codes P, M, and S.

Installation Notes

Installation is performed by machining technicians or CNC setup personnel. Power down and lock out the machine spindle before seating or indexing inserts. Verify the insert pocket and seating surfaces are clean and free of chips or debris before clamping. Follow the tool holder manufacturer torque specifications for the clamping screw and pin to ensure proper insert retention and runout control.
