Sandvik Coromant 5725053 CNMG543-MM 2025 Turning Insert

Product Description

The SANDVIK COROMANT 5725053 is a CNMG543-MM 2025 grade CVD-coated carbide turning insert engineered for metal cutting on CNC lathes and turning centers. It carries a multilayer TiCN, AI2O3, and TiN coating applied by CVD, which builds wear and crater resistance for extended tool life in demanding cuts. The 80-degree diamond insert shape (C) provides a strong cutting edge geometry, and the MM chip breaker geometry is optimized for chip control in continuous and interrupted turning operations. With a 0.5874-inch insert length and a 5/8-inch inscribed circle, this insert fits standard CNMG-style toolholders used across production and job-shop turning applications.

This insert is primarily intended for turning stainless steel workpieces, aligning with ISO material code M. It is suited for both roughing and finishing passes where controlled chip evacuation and edge toughness are required. The neutral hand orientation makes it adaptable to a wide range of toolholder configurations. The T-Max P series designation indicates compatibility with SANDVIK COROMANT T-Max P clamping toolholders that accept CNMG 16 06 12 inserts per ISO code CNMG 16 06 12-MM 2025. Machinists and CNC operators working in aerospace, food processing, chemical, and general manufacturing environments where stainless steel is the primary workpiece material will find this insert a direct-fit solution.

Key Features

• CVD multilayer coating: TiCN, AI2O3, and TiN for high wear resistance and thermal stability
• MM chip breaker geometry designed for effective chip control on stainless steel
• 80-degree diamond insert shape with 4 cutting edges for maximum indexing value
• 3/64-inch (0.0469-inch) corner radius balances edge strength with surface finish quality
• Neutral hand orientation compatible with a broad range of CNMG toolholder setups
• Clamp and pin insert holding method for rigid, repeatable seating in the toolholder pocket

Compatibility

Designed for use in SANDVIK COROMANT T-Max P series toolholders accepting CNMG 16 06 12 inserts per ISO designation CNMG 16 06 12-MM 2025. Compatible with standard CNMG-style toolholder pockets using clamp and pin insert holding.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Before indexing or replacing inserts, confirm the machine spindle is fully stopped and locked out per facility lockout/tagout procedures. Use the appropriate torx or hex key to seat the clamp screw to the toolholder manufacturer's specified method without over-torquing. Inspect the toolholder pocket and locating pin for wear or debris before seating the new insert to ensure accurate positioning and prevent premature edge failure.
