Ingersoll Cutting Tools 5609788 Turning Insert SPMT110408-EM

Product Description

The INGERSOLL CUTTING TOOLS 5609788 is a solid carbide turning insert in the SPMT series, grade TT8020, with a PVD-applied TiCN coating for extended tool life in demanding cutting applications. It features a 90-degree square shape with a positive rake geometry and a corner radius of 0.031 inches, making it well suited for general turning operations where clean, consistent edge performance is required. With four usable cutting edges per insert and a maximum depth of cut of 0.422 inches, this insert is designed for productive material removal across a wide range of workpiece materials. Licensed machinists and CNC lathe operators install this type of insert in standard screw-held toolholders.

This insert is intended for turning steel, stainless steel, and cast iron as primary workpiece materials, and is also rated for secondary applications including hard metals, superalloys, titanium, and non-ferrous alloys. The EM chip breaker geometry controls chip flow effectively across medium to heavy cutting conditions. It is suitable for both roughing and semi-finishing passes in production or job-shop environments on CNC or manual lathes. The neutral hand orientation gives it flexibility across a range of toolholder configurations.

Installation Notes

Installation is performed by a machinist or CNC toolroom technician. Power down and lock out the machine before indexing or replacing inserts. Seat the insert fully against the toolholder pocket locating surfaces and tighten the clamping screw to the toolholder manufacturer's specification. Inspect the cutting edge and chip breaker for damage before resuming cuts.
