Hertel 1001133 TPG432 HC210 Carbide Turning Insert

Product Description

The HERTEL 1001133 is a solid carbide turning insert in the TPG432 style, designed for precision metal turning operations on CNC lathes and manual turning centers. This triangular insert features a 60-degree included angle, a 1/2-inch inscribed circle, and a 1/32-inch corner radius. The substrate is solid carbide with a TiN (titanium nitride) coating applied via PVD process, which provides surface hardness and wear resistance at the cutting edge. The insert carries HERTEL grade HC210 and is intended for use by machinists and CNC operators working in production or job-shop environments.

This insert is suited for turning applications involving ISO material groups M (stainless steels), N (non-ferrous metals and plastics), and S (superalloys and titanium), with secondary suitability for group K (cast iron). The TPG432 style uses a clamp-type holding method with a positive rake geometry and neutral hand orientation, making it compatible with standard TPG-style toolholders. The KENDEX series designation applies. Maximum depth of cut is 1.25 mm (0.0492 inches). Typical applications include finish to semi-finish turning passes where edge geometry consistency and coating durability are priorities.

Key Features

• Solid carbide substrate with PVD TiN coating for improved wear resistance
• 60-degree triangular insert shape with a 1/32-inch corner radius for controlled surface finish
• Positive rake geometry with neutral hand orientation
• Clamp-type insert holding method compatible with standard TPG-style toolholders
• Grade HC210 rated for ISO material groups M, N, S, and K
• Maximum depth of cut: 1.25 mm (0.0492 inches)

Compatibility

Designed for use in TPG-style clamp-type toolholders accepting a 432 insert size. Confirm toolholder pocket specifications against the TPG432 insert style, 3/16-inch thickness, and 1/2-inch inscribed circle before installation.

Installation Notes

Turning inserts should be installed by a qualified machinist or CNC operator. Power down and lock out the machine before changing inserts. Use the appropriate torque wrench or clamp screw driver specified by the toolholder manufacturer to secure the clamp — do not overtighten by hand estimation. Inspect the insert seat and clamp for debris or damage before seating a new insert.
