Hertel 1000240 TNG322 HT10 Solid Carbide Turning Insert

Product Description

The HERTEL 1000240 is a solid carbide, uncoated turning insert in the TNG322 style, part of the KENDEX series. This triangular insert features a 60-degree included angle, a 3/8 inch inscribed circle (IC), and a 1/32 inch corner radius. At 0.65 inches in length and 1/8 inch thick, it is designed for neutral-hand turning operations. The uncoated solid carbide construction suits applications where a bare substrate provides optimal edge sharpness and heat resistance. Tooling specialists and CNC machinists install this insert into compatible clamp-style toolholders for precision turning work.

This insert is suited for turning operations on workpiece materials classified under ISO material groups N and S as primary, and K and M as secondary. Group N covers non-ferrous metals such as aluminum and copper alloys, while group S targets heat-resistant superalloys and titanium. Group K covers cast irons and group M addresses stainless steels. The TNG322 profile and KENDEX series designation make this insert a fit for shops running moderate material removal on CNC lathes and turning centers where sharp, consistent edge geometry is required.

Compatibility

Designed for use in clamp-style TNG-compatible toolholders that accept a 3/8 inch IC triangular turning insert. Verify toolholder specifications for TNG322 insert style and clearance code N before installation.

Installation Notes

Installation of turning inserts should be performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before seating or replacing any insert. Use the correct torque wrench and clamp screw specified by the toolholder manufacturer — do not overtighten or use damaged clamp hardware. Inspect the toolholder pocket and seating surface for chips or wear before installing the new insert.
