Sandvik Coromant 5740677 Turning Insert RCMT10T3M0-SM H13A

Product Description

The SANDVIK COROMANT 5740677 is a solid carbide, uncoated turning insert in the RCMT style, designed for precision turning operations in metalworking and machining environments. Part of the CoroTurn 107 series, this insert features a round shape with a full radius cutting edge, a 10 mm inscribed circle, and a 5/32 inch insert thickness (0.1563 inches). It carries a 7-degree relief angle and a neutral hand orientation. The SM chip breaker geometry is engineered specifically for stainless steel applications, making it well suited for demanding cuts where edge integrity and chip control are critical. Installation and tool management are simplified by its screw-holding method and four available cutting edges per insert.

This insert is intended for use in turning applications targeting stainless steel as the primary workpiece material, with secondary compatibility for superalloys and titanium. The CoroTurn 107 series is widely used in both production and job-shop environments where round inserts are required for profiling, copy turning, and contour operations. It fits toolholders designed for RCMT-style inserts and is applicable across a range of CNC lathes and turning centers used by professional machinists and tooling specialists in precision manufacturing.

Installation Notes

This insert is installed and serviced by qualified machinists or CNC tooling technicians. Power down and lock out all machine spindles before indexing or replacing inserts. Use the appropriate Torx or hex key to secure the clamping screw to the toolholder manufacturers specified seating torque. Inspect the insert pocket and seating surface for debris or damage before each insert change to ensure accurate positioning and consistent cutting performance.
