Sandvik Coromant 6292960 Turning Insert CNMG321MF 1125

Product Description

The SANDVIK COROMANT 6292960 is a CNMG-style indexable turning insert from the T-Max P series, designed for external and internal turning operations on CNC lathes and turning centers. It carries manufacturer grade 1125 with a dual-layer TiAlN and AlCr2O3 coating applied via PVD process, delivering wear resistance and thermal stability across a broad range of cutting conditions. The insert geometry is 80-degree diamond (shape code C), neutral hand, with an MF chip breaker suited for medium to finish turning passes. Insert length measures 9.67 mm (0.3807 inches) with a 3/8-inch inscribed circle and a 1/64-inch (0.40 mm) corner radius. Holding method is clamp and pin, clearance code N, tolerance code M.

This insert is intended for turning steel as its primary workpiece material, and is also rated for stainless steel, superalloy, and titanium applications. The MF chip breaker geometry performs well in light-to-medium depth-of-cut scenarios, with a maximum depth of cut of 9.27 mm (0.365 inches). Typical install environments include production turning on manual or CNC lathes in job shops, manufacturing facilities, and maintenance shops. The insert suits machinists working ISO material group P and M workpieces who need consistent chip control and surface finish at moderate feed rates.

Compatibility

Designed for use in toolholders accepting CNMG 09 03 04 inserts (ISO code CNMG 09 03 04-MF 1125) with clamp and pin holding methods. Confirms fitment with T-Max P series tooling systems. Verify toolholder pocket geometry and insert size code 321 prior to installation.

Installation Notes

Insert installation should be performed by a qualified machinist or toolroom technician with the machine spindle locked out and all axis motion disabled. Seat the insert fully into the pocket before engaging the clamp or pin; an improperly seated insert can fracture under cutting load. Inspect the insert pocket for chips or debris before indexing to a fresh cutting edge. Follow the toolholder manufacturer torque and clamping specifications for the specific holder in use.
