Sandvik Coromant 5725166 Turning Insert CNMG543-QM H13A

Product Description

The SANDVIK COROMANT 5725166 is a solid carbide, uncoated turning insert in the CNMG543-QM H13A designation, part of the T-Max P series. It carries an 80-degree diamond insert shape with a neutral hand orientation and a QM chip breaker geometry. The inscribed circle measures 5/8 inch (0.6250 inches), insert length is 0.5874 inches, and corner radius is 3/64 inch (0.0469 inches). With four cutting edges and an H13A grade designation, this insert is engineered for general turning operations where consistent chip control and edge integrity are priorities. Licensed machinists and CNC turning center operators are the primary installers of this insert type.

This insert is suited for turning steel as its primary workpiece material, with stainless steel as a secondary application. It fits standard CNMG toolholders with a clamp and pin holding method. Typical install scenarios include external turning on CNC lathes and manual turning centers in production and job shop environments. The ISO code for this insert is CNMG 16 06 12-QM H13A, which can be used to cross-reference toolholder compatibility within the T-Max P series.

Compatibility

Designed for use in CNMG-style toolholders with clamp and pin clamping systems within the T-Max P series. Compatible with toolholders accepting a 5/8-inch inscribed circle insert with a 1/4-inch hole diameter. Primary workpiece material is steel (ISO material code P); secondary workpiece material is stainless steel (ISO material code M).

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine before changing inserts. Use the appropriate torque wrench and manufacturer-specified clamping hardware to seat the insert securely in the toolholder pocket. Inspect the insert pocket and clamping components for wear or damage before installing a new insert.
