Sandvik Coromant 5724079 Turning Insert Carbide Diamond

Product Description

The SANDVIK COROMANT 5724079 is a solid carbide turning insert from the CoroTurn 107 series, designed for external and internal turning operations on steel and stainless steel workpieces. The insert carries the ISO designation CCGT 09 T3 01-UM 1125 and features a dual-layer TiAlN and AlCr2O3 coating applied via a PVD process, delivering thermal and wear resistance at the cutting edge. The 80-degree diamond shape (CCGT insert style) with a neutral hand orientation suits a wide range of finish-turning applications. The UM chip breaker geometry is optimized for light to medium depths of cut in P and M workpiece material classes. This insert is installed by machinists and CNC lathe operators in production and job-shop environments.

The 5724079 is suited for finish and semi-finish turning of steel (ISO material code P) and stainless steel (ISO material code M) in both production and job-shop settings. The screw-hold clamping method is standard for CoroTurn 107 toolholders that accept CCGT-style inserts with the corresponding 4.40 mm hole diameter. The UM chip breaker geometry supports controlled chip formation during lighter finishing passes, reducing surface roughness on close-tolerance turned components. This insert is a single-insert package sold in minimum order quantities of 10 units.

Key Features

• 80-degree diamond insert shape (code C) with neutral hand orientation for versatile turning setups
• TiAlN and AlCr2O3 dual-layer PVD coating for wear resistance on steel and stainless steel
• UM chip breaker geometry designed for finish to semi-finish turning passes
• 0.0039 inch (0.10 mm) corner radius for fine surface finish requirements
• Screw-hold insert retention method compatible with standard CoroTurn 107 toolholders
• 2 usable cutting edges per insert

Compatibility

Designed for use in CoroTurn 107 series toolholders that accept CCGT-style inserts with a screw-hold clamping method. Intended for machining ISO P (steel) and ISO M (stainless steel) workpiece materials. Compatible toolholders must accommodate the 4.40 mm (0.1732 inch) hole diameter and 3.97 mm insert thickness.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC operator with the machine fully stopped and locked out per applicable safety procedures. Seat the insert fully against the pocket locating surfaces before torquing the clamping screw to the toolholder specification. Inspect the insert pocket for chips or debris before seating a new insert, as contamination can cause premature edge failure or dimensional error. Index or replace the insert at first sign of flank wear, chipping, or deteriorating surface finish on the workpiece.
