Hertel 1000409 SPG322 HC210 Carbide Turning Insert

Product Description

The HERTEL 1000409 is a solid carbide turning insert in the SPG322 style, designed for use on CNC lathes and manual turning centers in metalworking and machining operations. It carries a TiN (titanium nitride) coating applied via PVD process, which improves wear resistance and extends cutting tool life compared to uncoated carbide. The insert features a 3/8-inch inscribed circle, a 1/32-inch corner radius, a 90-degree square shape, and a neutral hand orientation. It belongs to the KENDEX series and is manufactured to grade HC210. Machinists and tool and die professionals are the primary installers and users of this insert.

This insert is suited for turning operations on a range of workpiece materials, including stainless steel, non-ferrous metals, and high-temperature alloys, corresponding to ISO material groups M, N, and S as primary workpiece materials, with cast iron (group K) as a secondary material. It is also rated to material grades C2 and C4. Typical applications include finish and semi-finish turning passes where a controlled corner radius and consistent chip formation are required. The maximum depth of cut is 0.0492 inches (1.25 mm), making this insert appropriate for light to moderate material removal on precision turning jobs.

Installation Notes

Installation is performed by qualified machinists or tool-room technicians. Before changing inserts, power down the lathe and ensure the spindle is fully stopped. Seat the insert firmly in the toolholder pocket and secure the clamp to manufacturer torque specifications using the appropriate torque key. Inspect the insert seating and shim condition before resuming cutting operations.
