Hertel 1001132 TPMR432 HC335 Carbide Turning Insert

Product Description

The HERTEL 1001132 is a solid carbide turning insert in the TPMR432 geometry, designed for external and internal turning operations on CNC lathes and manual turning centers. This insert carries a CVD-applied multilayer coating of TiC, TiCN, and TiN under the HC335 manufacturer grade, which provides wear resistance and thermal protection during moderate to high-speed metal cutting. The triangular insert shape (60-degree included angle) with a neutral hand orientation suits a wide range of turning tool holders and boring bar assemblies. With a 0.5-inch inscribed circle and a 0.03125-inch corner radius, the 1001132 is well suited for finishing and light roughing passes where edge precision matters.

This insert is intended for machining steels (ISO P workpiece material code) and stainless steels (ISO M workpiece material code), covering material grades C5 and C6. It is used in production turning environments where consistent tool life and surface finish are required. The KENDEX series designation aligns this insert with compatible KENDEX-style clamping tool holders. A maximum depth of cut of 0.0492 inches (1.25 mm) positions this insert in the finishing to light semi-finish range. It is installed and changed by machinists and toolroom technicians in job shop, production, and maintenance machining applications.

Key Features

• 60-degree triangular insert shape with TPMR432 geometry and neutral hand orientation
• 0.5-inch inscribed circle and 0.03125-inch corner radius for precise edge engagement
• HC335 grade rated for ISO P (steel) and ISO M (stainless steel) workpiece materials
• R chip breaker configuration to manage chip flow during turning operations
• Clamp-style insert holding method compatible with KENDEX series tool holders

Compatibility

Designed for use with KENDEX series clamping-style turning tool holders that accept TPMR432 triangular inserts with a clamp holding method and a P clearance, M tolerance designation.

Installation Notes

Insert replacement should be performed by a qualified machinist with the machine spindle stopped and all axis motion disabled per shop lockout/tagout procedures. Use the appropriate torque wrench and clamp hardware specified by the tool holder manufacturer to seat the insert securely without over-torquing the clamping screw. Inspect the insert pocket for wear or debris before seating a new insert to ensure proper seating and edge alignment. Verify that the replacement insert grade and geometry match the job setup requirements before resuming cuts.
