Sandvik Coromant 7450171 Turning Insert RCMT1204M0 2220

Product Description

The SANDVIK COROMANT 7450171 is a round carbide turning insert in the CoroTurn 107 series, designed for external and internal turning operations on CNC lathes. It carries an RCMT insert style designation with a 12 mm inscribed circle, a 6 mm corner radius, and a neutral hand orientation. The insert is manufactured from solid carbide and finished with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, making it well suited for continuous and semi-interrupted cuts on stainless steel workpieces. With four available cutting edges per insert, it delivers consistent cost-per-edge performance in production turning environments.

This insert is intended for use in CoroTurn 107 toolholders configured for round RCMT-style inserts. The M0 chip breaker geometry is matched to medium-feed turning applications, particularly on austenitic and duplex stainless steel classified under ISO material group M. Typical install scenarios include general-purpose shaft turning, facing, and profiling on horizontal and vertical CNC turning centers in both job shop and high-volume production settings. Licensed machinists and CNC setup technicians are the primary users.

Key Features

• Round insert shape (code R) with 12 mm inscribed circle and 6 mm corner radius for smooth, stable cuts
• CVD multilayer coating — TiCN, Al2O3, TiN — provides heat resistance and wear protection on stainless steel
• Four cutting edges per insert for extended tool life and lower cost per edge
• M0 chip breaker geometry optimized for medium-feed turning on ISO M-group materials
• Neutral hand orientation compatible with both right- and left-hand toolholder setups
• Clamp and screw holding method for secure seating under cutting loads

Compatibility

Designed for use in CoroTurn 107 series toolholders accepting RCMT-style round inserts with a 12 mm inscribed circle. ISO code RCMT 12 04 M0 2220 identifies the insert geometry and grade for toolholder and catalog cross-reference.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the turret is indexed to a safe position before changing inserts. Inspect the insert pocket and clamping hardware for wear or debris before seating a new insert. Follow the toolholder manufacturer's torque and clamping procedure for RCMT round inserts to avoid insert rocking or premature edge failure.
