Sandvik Coromant 7080775 Turning Insert Rcmt Coroturn 107

Product Description

The SANDVIK COROMANT 7080775 is a round-style indexable turning insert designed for precision metal cutting in CNC and manual lathe applications. It belongs to the CoroTurn 107 series and carries the ISO designation RCMT 09 T3 00 4335. The insert is manufactured from solid carbide with a multi-layer CVD coating of TiCN, Al2O3, and TiN, making it well-suited for continuous and interrupted cuts in steel workpieces. With a 3/8-inch inscribed circle and a neutral hand orientation, it delivers consistent tool life across finishing and semi-finishing operations. Machinists, CNC operators, and tooling specialists working in production and job-shop environments are the primary users.

This insert is intended for steel turning applications in both production and job-shop settings. The CoroTurn 107 series is engineered for screw-clamped toolholders that accept RCMT-style round inserts. The neutral hand orientation makes it compatible with both left-hand and right-hand cutting directions. Its primary workpiece material designation is P-class steel, covering low-alloy, unalloyed, and carbon steels typical in general machining. No wiper edge is present, positioning this insert for standard surface finish requirements rather than high-feed finishing passes.

Key Features

• Round insert shape (RCMT) with 4 usable cutting edges for extended tool economy
• CVD multi-layer coating: TiCN, Al2O3, and TiN for wear resistance and thermal stability in steel cutting
• Manufacturer grade 4335 optimized for P-class steel workpiece materials
• 3/8-inch inscribed circle with 5/32-inch thickness for standard RCMT 09 toolholder seats
• Screw-clamped holding method with 0.1575-inch hole diameter for secure, repeatable seating
• 7-degree relief angle (clearance code C) with tolerance code M for dimensional consistency

Compatibility

Designed for screw-clamped toolholders accepting RCMT-style round inserts with a 3/8-inch inscribed circle, per the CoroTurn 107 series specification. ISO code RCMT 09 T3 00 applies for toolholder selection and insert pocket sizing.

Installation Notes

Installation is performed by machinists or CNC tooling technicians. The machine spindle must be stopped and the toolholder removed or secured before indexing or replacing the insert. Use the appropriate torx or hex key to remove the clamping screw, seat the new insert fully into the pocket, and retorque the screw to the toolholder manufacturer specification. Inspect the insert pocket for chips or debris before seating to avoid fracture at cutting edge startup.
