Sandvik Coromant 8003565 Turning Insert Rcmt 12 04 00-SM S205

Product Description

The SANDVIK COROMANT 8003565 is a round carbide turning insert from the CoroTurn 107 series, designed for single-point turning operations on superalloy and titanium workpieces. Carrying the ISO designation RCMT 12 04 00-SM S205, this insert features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN that provides wear resistance and thermal stability under the demanding cutting conditions associated with difficult-to-machine materials. The SM chip breaker geometry is optimized for controlled chip formation. With a 0.5-inch inscribed circle and a 0.25-inch corner radius, the insert suits medium-duty roughing and semi-finishing passes. Holding method is clamp or screw, and the neutral hand designation means it is not handed to a specific cut direction.

This insert is intended for use in external and internal turning applications where superalloys and titanium alloys are the primary workpiece materials, such as aerospace component machining, medical implant turning, and high-temperature alloy part production. The RCMT style and round insert shape allow full 360-degree indexing when mounted in compatible CoroTurn 107 toolholders, providing multiple usable cutting edges per insert. It is suited to both CNC lathe and manual lathe setups where a rigid, well-clamped toolholder is used.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for heat and wear resistance in superalloy and titanium cutting
• Round insert shape (RCMT) with full 360-degree usable cutting edge when indexed
• SM chip breaker geometry for controlled chip evacuation in difficult-to-machine materials
• Manufacturer grade S205 matched to superalloy and titanium primary workpiece materials
• Clamp and screw holding compatibility for secure seating in CoroTurn 107 toolholders
• Neutral hand orientation for flexible setup on external and internal turning operations

Compatibility

Designed for use with compatible CoroTurn 107 series toolholders accepting RCMT-style round inserts with a 0.5-inch inscribed circle. Verify toolholder pocket geometry and clamping system before installation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and de-energize the machine tool before indexing or replacing inserts. Use the correct torque driver or clamp screw tool as specified by the toolholder manufacturer to seat the insert firmly without over-torquing the clamping screw. Inspect the pocket seat for chips or debris before installing a fresh insert edge.
