Hertel 1002096 Turning Insert Dnmg 432-LF HC1250T Carbide

Product Description

The HERTEL 1002096 is a solid carbide coated turning insert in the DNMG 432-LF geometry, manufactured to grade HC1250T using a CVD coating process. It features a 55-degree diamond insert shape with a neutral hand orientation and a negative rake angle of 15 degrees. The inscribed circle measures 0.5 inches, the corner radius is 0.0315 inches (1/32 inch), and the insert length is 0.5 inches (12.70 mm). Designed for multi-edge indexable tooling systems, this insert is installed by machinists and CNC lathe operators working in production turning applications. The HC1250T grade is suited for steel and stainless steel workpiece materials per ISO material codes P and M.

This insert is intended for external and internal turning operations on CNC and manual lathes. The DNMG style with LF chipbreaker geometry is well suited for light finishing passes in steel and stainless alloys. The 55-degree diamond shape provides good access in profiling and contour turning. Maximum depth of cut is 1.50 mm (0.0591 inches), making it appropriate for finishing and light semi-finishing operations where tight tolerances and surface finish are priorities.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines and shop safety procedures. Power down and lock out the spindle before indexing or replacing inserts. Use the correct torque wrench and clamp hardware specified for the toolholder to avoid insert seating issues or clamp damage. Inspect the insert pocket and locating pin for wear or debris before seating a new insert.
