Sandvik Coromant 5752357 Turning Insert Coroturn 107

Product Description

The SANDVIK COROMANT 5752357 is a solid carbide turning insert in the CoroTurn 107 series, designed for external turning operations on CNC lathes and turning centers. It carries a PVD-applied TiAlN and AlCr2O3 dual-layer coating under manufacturer grade 1125, which is optimized for cutting steel and a broad range of secondary workpiece materials. The insert features a 60-degree triangular shape with three cutting edges, a left-hand cutting direction, and a corner radius of 0.02 mm (0.0008 inches). Insert holding is via screw clamp, and the chipbreaker designation is F. This insert is installed and replaced by machinists and CNC tooling technicians in production and job-shop environments.

This insert is suited for turning steel as the primary workpiece material, with secondary suitability for stainless steel, non-ferrous metals, superalloys, and titanium. The ISO code for this insert is TCEX 06 T1 00L-F 1125. It is a left-hand insert intended for applications where tool approach and chip flow direction require left-hand geometry. Typical use is in finish and semi-finish turning passes on a variety of ferrous and non-ferrous materials where tight dimensional control and surface finish consistency are required.

Key Features

• Solid carbide substrate with PVD-applied TiAlN and AlCr2O3 dual-layer coating for wear resistance across multiple material groups
• 60-degree triangular insert shape with 3 cutting edges for extended tool life per insert
• Left-hand cutting designation suits specific approach angles and chip evacuation requirements
• 0.02 mm (0.0008 inch) corner radius for controlled surface finish on finish and semi-finish passes
• F chipbreaker geometry for chip control across the rated workpiece material range
• Screw-clamp insert holding method for positive, repeatable seating in compatible toolholders

Compatibility

Designed for use in CoroTurn 107 series toolholders that accept TCEX-style inserts with a 1.21.200 size code and screw-clamp retention. Consult the SANDVIK COROMANT CoroTurn 107 toolholder selection guide to confirm holder compatibility before ordering.

Installation Notes

Installation and replacement of turning inserts should be performed by a qualified machinist or CNC tooling technician with the machine fully stopped and the spindle locked. Use the correct Torx or hex key specified for the CoroTurn 107 screw-clamp system and do not overtighten the clamping screw. Inspect the insert seat and clamp for wear or debris before seating a new insert to ensure proper contact and runout. Index or replace the insert at the first sign of chipping, built-up edge, or dimensional drift in the finished workpiece.
