Sandvik Coromant 5724966 Turning Insert CCMT431PF 5015

Product Description

The SANDVIK COROMANT 5724966 is a cermet, uncoated turning insert designed for precision finishing operations on steel and hardened materials. Manufactured to ANSI code CCMT431 and ISO code CCMT120404, this insert features an 80-degree diamond (rhombic) shape with a positive side clearance and a neutral hand orientation. The PF chip breaker geometry is engineered for finishing cuts, delivering tight tolerances and smooth surface finishes. With a 0.5-inch inscribed circle and a corner radius of 0.0157 inches (1/64 inch), this insert suits applications demanding high wear resistance in grade 5015 cermet. Licensed HVAC and mechanical trades are not the primary installers; this insert is used by CNC machinists and lathe operators working in precision metal-cutting environments.

The 5724966 is part of the CoroTurn 107 series and is suited for external turning, finish-turning, and light interrupted cuts on steel workpieces. It performs at its best in high-speed, low-feed finishing passes where surface finish and dimensional accuracy are the priority. Secondary workpiece materials include cast iron. The insert is screw-held and fits toolholders designed for CCMT-style inserts with a 5.5 mm hole diameter. It is available in single-piece packages with a minimum order quantity of 10 units.

Key Features

• Grade 5015 cermet with bright/uncoated finish — delivers high wear resistance for steel finishing and hardened material applications
• PF chip breaker geometry optimized for finishing operations with controlled chip evacuation
• 80-degree diamond insert shape (C) with positive side clearance for reduced cutting forces
• 0.0157-inch (1/64 inch) corner radius for fine surface finish on finishing passes
• Neutral hand orientation for use in both right-hand and left-hand toolholder setups
• 2 cutting edges per insert for cost-effective use

Compatibility

Designed for use with CCMT-style screw-clamp toolholders in the CoroTurn 107 series. Compatible with toolholders accepting a CCMT431 (ANSI) or CCMT120404 (ISO) insert seat. Suitable for CNC lathes and turning centers running steel (ISO P) and hardened material (ISO H) workpieces.

Installation Notes

Installation is performed by a qualified CNC machinist or toolroom technician. Ensure the machine spindle is fully stopped and the turret is locked before indexing or replacing inserts. Use the appropriate torx or hex key to secure the clamping screw to the toolholder manufacturer's specified procedure; do not overtighten, as this can fracture the insert. Inspect the insert seat and screw for wear or debris before seating a new insert.
