Hertel 1001950 Turning Insert Tnmg 432-H1Z HC305T Carbide

Product Description

The HERTEL 1001950 is a TNMG 432-H1Z style turning insert manufactured from solid carbide and finished with a CVD-applied Al2O3 (aluminum oxide) coating in the HC305T material grade. The insert features a 60-degree triangular shape with a neutral cutting hand, a 0.5-inch inscribed circle, and a 0.0313-inch (1/32 inch) corner radius. The cutting edge is honed for consistent engagement, and the FF proprietary coating designation combined with the G chip breaker geometry is suited for controlled chip formation. This insert is used by machinists and tool-and-die professionals on CNC and manual lathes for turning operations.

The HERTEL 1001950 is intended for turning applications on workpiece materials classified under ISO material group K, which includes cast irons and hardened materials. The neutral cutting direction makes it suitable for both right-hand and left-hand toolholder configurations. The TNMG insert style is compatible with standard TNMG-type clamp and pin holding systems. Typical applications include finish and semi-finish turning passes where surface finish consistency and edge life are priorities. The ISO designation for this insert is TNMG220408.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist following the toolholder manufacturer's torque specifications for the clamping screw. Ensure the toolholder pocket and seating surfaces are clean and free of chips before seating the insert. Power down and lock out the machine spindle before changing inserts. Do not use damaged or chipped inserts, as edge failure can affect workpiece quality and operator safety.
