Sandvik Coromant 7080752 Turning Insert TCMT32.51-UM 4335

Product Description

The SANDVIK COROMANT 7080752 is a solid carbide turning insert in the CoroTurn 107 series, designed for external and internal turning operations on CNC and manual lathes. Manufactured to ANSI code TCMT32.51 and ISO code TCMT 16 T3 04-UM 4335, this insert features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN for extended tool life in steel machining applications. The triangular insert shape provides three cutting edges, the UM chip breaker geometry supports both roughing and medium machining passes, and positive side clearance reduces cutting forces on the workpiece.

This insert is suited for steel turning applications where a balance of wear resistance and toughness is required, corresponding to ISO material group P (Steel). The UM chip breaker geometry handles roughing and medium machining cuts, making it practical for general-purpose turning in production shops, job shops, and maintenance environments. A licensed machinist or CNC operator would typically select this insert for carbon steel, alloy steel, and similar P-group materials where chip control and edge durability are priorities.

Key Features

• ANSI code TCMT32.51 and ISO code TCMT 16 T3 04-UM 4335 for standard toolholder compatibility
• CVD multilayer coating: TiCN, Al2O3, TiN for wear resistance in steel turning
• UM chip breaker geometry rated for roughing and medium machining operations
• Triangular insert shape (60-degree included angle) provides three usable cutting edges
• Corner radius of 0.0156 inches (1/64 inch) for light finishing and contour work
• Positive side clearance and screw-lock holding method for secure, repeatable seating
• Grade 4335 characteristics: moderate wear resistance with high toughness for steel applications

Compatibility

Designed for use in TCMT-style screw-lock toolholders compatible with ANSI size code 32.51 and ISO size code 16T304, as used in the Sandvik Coromant CoroTurn 107 toolholder system.

Installation Notes

Install and replace turning inserts with the machine fully stopped and locked out per applicable safety procedures. Use the correct Torx or hex key to seat the clamping screw snugly without over-torquing, as specified by the toolholder manufacturer. Inspect the insert pocket and seating surface for chips or debris before seating a new insert, as contamination causes premature edge failure. Qualified machinists and CNC operators should verify insert orientation and chip breaker direction before resuming cutting operations.
