Sandvik Coromant 5752081 Turning Insert Tcgt 60 Triangle

Product Description

The SANDVIK COROMANT 5752081 is a solid carbide turning insert in a TCGT triangular style with a 60-degree included angle, designed for precision external and internal turning operations. It features a TiAlN and AlCr2O3 PVD coating for wear resistance and thermal stability when cutting steel and related workpiece materials. The insert is left-hand oriented with a K chip breaker geometry and a 1/64 inch (0.0156 inch) corner radius, making it suitable for finishing and light-to-medium cutting passes. It fits the CoroTurn 107 series tooling system and is installed by licensed machinists and CNC machine tool operators in production and job-shop environments.

This insert is engineered for turning steel as its primary workpiece material, with secondary suitability for stainless steel, non-ferrous metals, superalloys, and titanium. Typical applications include external turning, boring, and profiling on CNC lathes where tight tolerances and fine surface finishes are required. The screw-holding method provides secure clamping and repeatable indexing across all three cutting edges. It is sold individually but requires a minimum order of 10 pieces per the manufacturer minimum order quantity.

Key Features

• TiAlN and AlCr2O3 PVD coating for enhanced wear resistance and thermal protection
• Left-hand orientation with K chip breaker geometry for controlled chip formation
• Three cutting edges for maximum insert utilization before replacement
• Screw-held mounting method for positive, repeatable seating in CoroTurn 107 holders
• 1/64 inch corner radius suited to finishing and light profiling passes
• Grade 1125 carbide substrate rated for steel, stainless steel, superalloys, and titanium

Compatibility

Designed for use with CoroTurn 107 series toolholders that accept TCGT-style screw-held triangular inserts. ISO designation TCGT 09 02 04L-K 1125 applies for cross-referencing compatible holders and sister inserts.

Installation Notes

Installation is performed by a qualified machinist or CNC toolroom technician. Ensure the machine spindle is fully stopped and all motion is locked out before indexing or replacing inserts. Use the appropriate Torx or hex key to seat the clamping screw to the torque specification listed in the CoroTurn 107 toolholder documentation. Inspect the insert pocket and locating surfaces for chips or debris before seating the new insert to maintain dimensional accuracy.
