Sandvik Coromant 7080690 RCMT1204M0 Turning Insert Cvd Carbide

Product Description

The SANDVIK COROMANT 7080690 is a round carbide turning insert in the CoroTurn 107 series, designed for external turning operations on steel workpieces. Manufactured to ISO code RCMT 12 04 M0 4335, it features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN that delivers wear resistance and thermal stability during continuous and light-interrupted cuts. The insert has a 12 mm inscribed circle, a 4.76 mm thickness, and a neutral hand orientation. It is held in place by a screw-type clamping method and carries the M0 chip breaker geometry. CNC machinists and turning center operators install this insert in compatible CoroTurn 107 toolholders for production steel turning.

The 7080690 is suited for roughing and finishing passes on steel components in job shop and production environments. Its round insert shape provides multiple re-indexing positions across 4 cutting edges, reducing per-edge tooling cost. The primary workpiece material classification is P-grade steel per ISO, making this insert appropriate for carbon steels, alloy steels, and cast steels encountered in general machining. The CoroTurn 107 platform is commonly used on CNC lathes and turning centers in both light and medium material removal applications.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for wear and heat resistance in steel cutting
• Round insert shape with 4 cutting edges for maximum indexing value
• 12 mm inscribed circle with M tolerance and C clearance code for consistent fitment
• M0 chip breaker geometry for controlled chip formation in steel turning
• Screw-type insert holding for secure, repeatable clamping in CoroTurn 107 holders
• Neutral hand orientation for flexible use in standard external turning setups

Compatibility

Designed for use with CoroTurn 107 series toolholders that accept RCMT 12 04 style round inserts with a screw clamping method. Primary workpiece material compatibility is ISO P-grade steel.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC tooling technician with the machine in a stopped, locked-out state. Use the correct Torx or hex key driver specified for CoroTurn 107 screw-lock toolholders when seating the insert. Inspect the insert pocket and clamping screw for debris or wear before seating a new insert. Do not overtighten the clamping screw, as this can fracture the carbide body.
