Hertel 1001201 TPG323 HT10 Solid Carbide Turning Insert

Product Description

The HERTEL 1001201 is a solid carbide, uncoated turning insert in the TPG323 style, designed for external turning operations on CNC and manual lathes. It features a triangular insert shape with a 60-degree included angle, a 3/8-inch inscribed circle, and a 3/64-inch corner radius. The HT10 carbide grade provides a balance of hardness and wear resistance suited for general-purpose turning. The neutral hand orientation makes it compatible with a wide range of toolholders. This insert is installed by machinists and CNC operators in production and job shop environments.

The 1001201 is suited for turning non-ferrous metals and other materials falling within ISO material groups N and S as primary workpiece materials, with K and M as secondary. It is part of the KENDEX series and carries the material grade designation C2, making it appropriate for applications requiring clean cutting edges without the added tool pressure of a coated insert. Typical uses include finish and semi-finish turning passes where surface finish and edge consistency are priorities.

Key Features

• Solid carbide construction, uncoated, for sharp, low-friction cutting performance
• TPG323 insert style with positive rake geometry for reduced cutting forces
• 3/8-inch inscribed circle and 60-degree triangle shape for broad toolholder compatibility
• 3/64-inch corner radius suitable for semi-finish to finish turning
• Maximum depth of cut of 0.0492 inches (1.25 mm) for controlled material removal
• Clamp-style insert holding method with G tolerance and P clearance code

Compatibility

Designed for use in TPG-style toolholders accepting a 3/8-inch inscribed circle triangular insert with clamp-style retention, consistent with KENDEX series toolholder specifications.

Installation Notes

This insert is seated and secured by a machinist or CNC operator using a clamp-style toolholder; ensure the toolholder pocket and seating surfaces are clean and free of chips before indexing or replacing the insert. Power down and lock out the machine spindle before servicing any cutting tool. Follow the toolholder manufacturer's torque specifications for the clamping screw. Dispose of worn inserts according to applicable shop waste procedures for carbide tooling.
