Sandvik Coromant 5725006 Turning Insert CNMG543-MR 2035

Product Description

The SANDVIK COROMANT 5725006 is a CNMG-style turning insert in the T-Max P series, engineered for precision metal cutting on CNC lathes and turning centers. It features a solid carbide substrate with a PVD-applied TiAlN and TiN coating, making it well suited for demanding cutting applications where heat resistance and edge retention are critical. The insert has a neutral hand orientation, an 80-degree diamond shape, a 5/8-inch inscribed circle, and a 3/64-inch corner radius. With four usable cutting edges per insert, it delivers cost-effective tooling life in production environments. Licensed machinists and CNC operators working in job shops or production facilities are the primary users.

This insert is designed primarily for turning stainless steel workpieces, consistent with its M-grade primary workpiece material classification. The MR chip breaker geometry is optimized to manage chip flow in medium cutting conditions. The T-Max P series is a widely recognized platform in external and internal turning operations across both roughing and semi-finishing passes. The CNMG form factor seats in standard CNMG toolholders using clamp and pin holding methods, making it compatible with a broad range of commercially available turning tool bodies.

Key Features

• PVD-coated TiAlN and TiN multilayer coating for elevated heat resistance and extended edge life
• 80-degree diamond insert shape provides strong cutting edge geometry suitable for profiling and straight turning
• MR chip breaker geometry designed for effective chip control in medium-duty stainless steel turning
• Four cutting edges per insert reduce per-edge tooling cost in production runs
• Neutral hand orientation allows use in both left- and right-hand toolholder setups
• Clamp and pin insert holding method provides rigid, repeatable seating in compatible toolholders

Compatibility

Designed for use in standard CNMG-style turning toolholders that accept a 5/8-inch inscribed circle insert with clamp and pin holding. ISO code CNMG 16 06 12-MR 2035 can be used to cross-reference compatible toolholder specifications. Primary workpiece material classification is M, corresponding to stainless steel applications.

Installation Notes

Insert replacement should be performed by a qualified machinist or CNC tooling technician with the machine fully stopped and locked out per applicable safety procedures. Ensure the toolholder pocket and clamping surfaces are clean and free of chips before seating the insert. Use the correct torque wrench and manufacturer-specified clamping hardware for the toolholder model in use — do not overtighten or use improvised tools. Inspect the insert seat and chip breaker geometry before resuming cutting operations to confirm proper orientation.
