Sandvik Coromant 5724968 Turning Insert CCMT431-MF 1115

Product Description

The SANDVIK COROMANT 5724968 is a CCMT431-MF solid carbide turning insert from the CoroTurn 107 series, designed for precision external and internal turning operations. The insert features a TiAlN and AlCr2O3 PVD coating applied over a carbide substrate, delivering heat resistance and edge stability at elevated cutting speeds. With an 80-degree diamond shape, a 0.5-inch inscribed circle, and a 0.0156-inch corner radius, this insert provides the geometry required for semi-finishing and finishing passes on difficult-to-machine materials. It is installed by licensed machinists and CNC turning center operators in production and job-shop environments.

This insert is engineered primarily for machining stainless steel (ISO material code M) and is rated as a secondary-application insert for superalloys and titanium (ISO material code S). The MF chip breaker geometry is optimized for light chip loads and fine finishing cuts, making it well suited for close-tolerance diameter work and surface finish requirements typical in aerospace, medical, and fluid-handling component production. The neutral hand orientation provides flexibility in both right-hand and left-hand toolholder configurations that accept CCMT geometry inserts.

Key Features

• TiAlN and AlCr2O3 PVD coating for thermal stability and wear resistance on stainless steel and superalloys
• 80-degree diamond insert shape (C) with 7-degree relief angle for positive cutting geometry
• MF chip breaker geometry optimized for semi-finishing and finishing chip control
• Screw-held mounting with a 0.2165-inch hole diameter for secure clamping in CCMT-style toolholders
• Two cutting edges per insert maximize tool utilization
• ISO code CCMT 12 04 04-MF 1115 for straightforward cross-referencing to toolholder catalogs

Compatibility

Designed for use in CCMT-style screw-clamp turning toolholders accepting a 1/2-inch inscribed circle insert with clearance code C and tolerance code M. Part of the SANDVIK COROMANT CoroTurn 107 series system.

Installation Notes

Installation and indexing should be performed by a qualified machinist or CNC toolroom technician with the machine powered off and the spindle locked. Use the appropriate Torx or hex key specified by the toolholder manufacturer when tightening the clamp screw — do not over-torque. Inspect the insert pocket and seating surface for chips or debris before seating the insert. Always verify insert orientation and cutting-edge engagement before resuming machine operation.
