Sandvik Coromant 5730986 Turning Insert DCMT32.52-UM 1115

Product Description

The SANDVIK COROMANT 5730986 is a solid carbide turning insert designed for precision metal cutting in CNC lathe and turning center applications. Manufactured under the CoroTurn 107 series, this DCMT-style insert features a 55-degree diamond shape with a neutral hand orientation. The insert is coated with TiAlN and AlCr2O3 via a PVD coating process, delivering high heat resistance and extended tool life when cutting demanding materials. With a 3/8-inch inscribed circle and a 1/32-inch corner radius, it is suited for finishing and semi-finishing operations where tight tolerances and consistent surface quality are required.

This insert is primarily intended for machining stainless steel and is also rated for secondary use on superalloys and titanium. It fits screw-held toolholders compatible with the DCMT insert style and is a standard choice for turning operations in aerospace, medical, and industrial manufacturing environments. The ISO designation is DCMT 11 T3 08-UM 1115. The UM chip breaker geometry is optimized for controlled chip evacuation in these difficult-to-machine material groups. Minimum order quantity is 10 inserts; each package contains 1 insert.

Key Features

• TiAlN and AlCr2O3 PVD coating for high-temperature wear resistance on stainless steel and superalloys
• 55-degree diamond insert shape (DCMT) with 7-degree relief angle for positive cutting geometry
• UM chip breaker designed for controlled chip formation in stainless steel and titanium
• 1/32-inch corner radius for finishing and semi-finishing surface finish requirements
• 2 cutting edges per insert for cost-effective tool management
• Screw-held mounting via center hole for secure clamping in compatible toolholders

Compatibility

Designed for use in screw-held DCMT-style toolholders compatible with the CoroTurn 107 series. ISO code DCMT 11 T3 08-UM 1115 can be used to cross-reference compatible holder systems. Intended for turning applications on stainless steel (ISO material group M) with secondary suitability for superalloys and titanium (ISO material group S).

Installation Notes

Insert replacement and seating should be performed by a qualified machinist or tooling technician with the machine fully stopped and locked out per established machine safety procedures. Ensure the insert pocket and clamping screw are clean and free of debris before seating the insert to maintain proper geometry and prevent premature wear. Use the correct torque driver for the clamping screw as specified by the toolholder manufacturer. Inspect the insert seat and screw threads for damage each time inserts are indexed or replaced.
