Sandvik Coromant 5724954 Turning Insert CCMT431-MM 2035

Product Description

The SANDVIK COROMANT 5724954 is a CCMT-style solid carbide turning insert designed for precision external and internal turning operations. Coated with TiAlN and TiN via a PVD process, this insert carries the 2035 manufacturer grade and is engineered primarily for machining stainless steel workpieces. It features an 80-degree diamond insert shape, a neutral hand orientation, and an MM chip breaker geometry that promotes controlled chip flow and surface finish consistency. With a 0.5000-inch inscribed circle and a 0.0156-inch corner radius, the insert suits finishing and semi-finishing passes where edge integrity and dimensional accuracy are critical. Installation and use fall under the CoroTurn 107 series platform.

This insert is suited for CNC turning centers and lathes where a screw-on holding method is used. The CCMT form factor is widely applied in both production shop and job shop environments for turning stainless steel and similar ISO M-group materials. With two cutting edges per insert, it offers a cost-effective service life in moderate to light-duty turning applications. Machinists working on close-tolerance stainless components will find the MM chip breaker geometry particularly effective at managing the tough, stringy chips typical of austenitic stainless alloys.

Key Features

• PVD-applied TiAlN and TiN dual coating for wear resistance on stainless steel and ISO M-group materials
• MM chip breaker geometry for controlled chip evacuation in semi-finishing and finishing cuts
• 80-degree diamond insert shape (CCMT) with neutral hand orientation for versatile toolholder compatibility
• 0.0156-inch corner radius supports tight-tolerance finishing passes
• Two cutting edges per insert maximize usable tool life
• Screw-on insert holding method compatible with CoroTurn 107 series toolholders

Compatibility

Designed for use with CoroTurn 107 series toolholders that accept CCMT-style inserts with a screw-on holding method. ISO code CCMT 12 04 04-MM 2035 identifies the exact insert geometry for toolholder cross-reference. Specific compatible toolholder part numbers were not provided in the available product data; consult the CoroTurn 107 toolholder selection guide for confirmed pairings.

Installation Notes

Insert changes should be performed with the machine in a full stop, lockout-tagout state, with all axis motion disabled. Use the appropriate Torx or hex key specified by the toolholder manufacturer to seat the clamping screw; do not overtighten, as this can crack the carbide substrate. Inspect the insert pocket and seating surface for chips or debris before seating a new insert. Proper insert orientation must be confirmed before resuming cuts, particularly when indexing to the second cutting edge.
