Sandvik Coromant 5723327 Turning Insert CCMT32.51-MM

Product Description

The SANDVIK COROMANT 5723327 is a solid carbide turning insert designed for precision external and internal turning operations on CNC lathes and turning centers. Carrying the CCMT32.51-MM geometry with a 1105 grade PVD TiAlN coating, this insert delivers controlled wear resistance and thermal stability at elevated cutting speeds. The 80-degree diamond insert shape provides a strong cutting edge with a 1/64 inch (0.0156 inch) corner radius. With two usable cutting edges per insert, it is suited for medium-duty turning passes where consistent surface finish and dimensional accuracy are priorities. Licensed machinists and CNC operators install this insert as part of routine tooling maintenance in production and job-shop environments.

This insert belongs to the CoroTurn 107 series, optimized for screw-clamped toolholders accepting CCMT-style inserts. Its primary workpiece material rating is steel (ISO code P), with a secondary rating for stainless steel (ISO code M). The chip breaker geometry is MM, which is engineered for medium-cut finishing and semi-finishing passes. The ISO designation is CCMT 09 T3 04-MM 1105. Typical applications include turning shafts, flanges, and precision-machined components in aerospace, automotive, and general metalworking production environments.

Key Features

• PVD TiAlN coating for high thermal resistance and extended tool life in steel and stainless steel cutting
• 80-degree diamond insert shape (shape code C) with 7-degree relief angle for positive cutting geometry
• MM chip breaker optimized for medium finishing and semi-finishing cuts
• Two cutting edges per insert for cost-efficient tooling consumption
• Screw-clamped insert holding method for secure, repeatable seating in CCMT-compatible toolholders
• CoroTurn 107 series compatibility for use across a broad range of standard turning toolholders

Compatibility

Designed as an OEM-style replacement insert for screw-clamped toolholders accepting CCMT 09 T3 geometry inserts within the CoroTurn 107 series platform.

Installation Notes

This insert is installed by qualified CNC machinists or toolroom technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torx or hex key to seat the clamping screw to the toolholder manufacturer's specification, and inspect the insert pocket for chips or debris before seating. Handle carbide inserts with care to avoid chipping the cutting edges prior to use.
