Sandvik Coromant 5740690 Turning Insert RCMT10T3M0-SM 1105

Product Description

The SANDVIK COROMANT 5740690 is a round solid carbide turning insert carrying ISO designation RCMT 10 T3 M0-SM 1105. It is designed for external and internal turning operations on CNC lathes and turning centers. The insert features a TiAlN2 coating applied via PVD process, which provides thermal resistance and extended tool life in a wide range of workpiece materials. A 10 mm inscribed circle and 3.97 mm insert thickness define its cutting geometry. The neutral hand orientation makes it usable in both left- and right-hand toolholders. Licensed machinists and CNC operators install this insert as part of routine tooling maintenance and setup.

This insert belongs to the CoroTurn 107 series and is intended for finishing and semi-finishing turning applications. It seats in screw-clamped toolholders that accept the RCMT insert style with a 4.40 mm hole diameter. The rounded insert shape delivers consistent, repeatable cutting edges with no defined lead angle dependency, making it well suited for profiling passes and contour turning on both ferrous and select non-ferrous materials. The T chip breaker geometry supports chip control across a range of feed rates typical in production turning environments.

Key Features

• TiAlN2 PVD coating for improved heat resistance and wear performance
• Round insert shape (code R) enables full 360-degree usable cutting edge rotation
• Screw-clamped holding method provides rigid, repeatable seating in compatible toolholders
• Neutral hand orientation fits both left- and right-hand toolholder configurations
• T chip breaker geometry supports controlled chip evacuation during turning passes
• ISO code RCMT 10 T3 M0-SM 1105 for direct cross-reference and toolholder matching

Compatibility

Designed for use in RCMT-style screw-clamped toolholders within the SANDVIK COROMANT CoroTurn 107 series. Verify toolholder bore and pocket geometry against the ISO RCMT 10 T3 M0 designation before installation.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. The machine spindle must be stopped and the turret fully indexed to a safe position before changing inserts. Use the appropriate Torx or hex key to seat the clamping screw to the toolholder manufacturer specification — do not overtighten, as carbide inserts are brittle and can fracture under excess clamping force. Inspect the insert pocket and seating surface for chips or debris before installing the new insert.
