Sandvik Coromant 5752790 Turning Insert TCMT32.52-MM 2035

Product Description

The SANDVIK COROMANT 5752790 is a TCMT-style triangular turning insert designed for precision metal-cutting operations on CNC lathes and turning centers. It carries the manufacturer grade 2035 and features a PVD-applied TiAlN and TiN dual coating that supports extended tool life when machining stainless steel and other difficult materials. The insert has a 3/8-inch inscribed circle, a 0.618-inch cutting edge length, and a 1/32-inch corner radius. The MM chip breaker geometry controls chip flow in medium finishing and semi-finishing cuts. Licensed machinists and CNC operators install this insert as a direct replacement in CoroTurn 107 tooling systems.

This insert is sized and toleranced for use in CoroTurn 107 series toolholders. Its primary workpiece material designation is M, indicating suitability for stainless steel and similar ISO M-group materials. The screw-lock holding method and TCMT geometry make it appropriate for both external and internal turning applications where a positive rake angle and reliable chip control are required. The neutral hand orientation allows use in standard right-hand toolholder pockets without modification. Typical applications include finish turning and semi-finishing on stainless steel components in general machining, aerospace, and medical manufacturing environments.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the correct Torx or hex key to tighten the clamping screw to the toolholder manufacturer's specified seating procedure — do not overtighten, as this can crack the carbide. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert.
