Hertel 1001123 TPG322 HC335 Carbide Turning Insert

Product Description

The HERTEL 1001123 is a solid carbide turning insert in the TPG322 style, designed for single-point turning operations on CNC and manual lathes. This triangular insert carries an HC335 manufacturer grade and features a CVD-applied multilayer coating of TiC, TiCN, and TiN, which provides wear resistance and extended tool life across a range of workpiece materials. The insert measures 16.5 mm (0.6496 inches) in length with a 3/8-inch inscribed circle and a 1/32-inch corner radius. It uses a clamp-style holding method and is suited for machinists and toolroom technicians running turning operations at moderate to high cutting speeds.

This insert is used in precision turning applications on ferrous metals and stainless steels. It falls under primary workpiece material category P (carbon and alloy steels) and secondary category M (stainless steels), matching material grades C5 and C6. The neutral hand orientation and positive rake geometry make it appropriate for general-purpose external turning and facing. It belongs to the KENDEX series and fits toolholders designed for TPG-style inserts. Typical install scenarios include production turning cells and job-shop lathes where consistent chip control and surface finish are required.

Key Features

• CVD-coated with TiC, TiCN, and TiN multilayer for improved wear and heat resistance
• HC335 carbide grade suited for P and M workpiece material categories
• Triangular insert shape with 60-degree included angle and positive rake geometry
• 1/32-inch corner radius for controlled surface finish in turning operations
• Clamp-style holding method compatible with standard TPG toolholders
• Maximum depth of cut of 1.25 mm (0.0492 inches) for finishing and light roughing passes

Compatibility

Designed as an OEM-style replacement or direct-fit insert for toolholders accepting TPG322-style solid carbide inserts with a clamp holding method and P clearance code.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the lathe spindle before seating or replacing inserts. Use the appropriate clamp screw torque as specified by the toolholder manufacturer. Inspect the insert pocket and clamp for wear or damage before installing a new insert to ensure proper seating and runout control.
