Sandvik Coromant 5749392 Turning Insert SCMT32.52-UM

Product Description

The SANDVIK COROMANT 5749392 is a solid carbide turning insert designed for precision external turning operations on CNC lathes and turning centers. Carrying the SCMT32.52-UM 1125 designation, this insert features a TiAlN and AlCr2O3 PVD coating applied over a carbide substrate, delivering strong wear resistance and thermal stability at the cutting edge. The UM chip breaker geometry supports chip control across a wide range of feed rates and depths of cut. With a neutral hand orientation and a 90-degree square insert shape, it fits standard SCMT-style toolholders and is installed by licensed machinists and tooling technicians working in production turning environments.

This insert is suited for turning steel as its primary workpiece material, with secondary capability on stainless steel, non-ferrous metals, superalloys, and titanium. The CoroTurn 107 series is commonly applied in light to moderate roughing and finishing passes on external diameters, shoulders, and faces. The four cutting edges per insert make it cost-effective for high-volume production runs where insert index cycles are tracked. Typical applications include shaft turning, sleeve machining, and general-purpose OD turning in job shop and production environments.

Key Features

• TiAlN and AlCr2O3 PVD coating for elevated wear and heat resistance at the cutting edge
• UM chip breaker geometry promotes reliable chip evacuation across varied feed and depth conditions
• Four usable cutting edges per insert maximize tooling value in production runs
• Neutral hand orientation compatible with standard SCMT screw-clamping toolholders
• 1/32 inch corner radius suitable for general-purpose turning with moderate corner strength
• Grade 1125 carbide substrate engineered for steel and multi-material turning applications

Compatibility

Designed for use in SCMT-style screw-clamping toolholders within the SANDVIK COROMANT CoroTurn 107 series. ISO designation SCMT 09 T3 08-UM 1125. Compatible primary workpiece material is steel (ISO P); secondary compatible materials include stainless steel (ISO M), non-ferrous metals (ISO N), superalloys (ISO S), and titanium.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate Torx or hex key to secure the clamping screw to the toolholder manufacturer's specified procedure. Inspect the insert seat and clamping screw for debris or damage before seating a new insert to ensure proper seating and edge registration.
