Hertel 1001124 CNMG432R HC335 Turning Insert 0.5in Ic

Product Description

The HERTEL 1001124 is a CNMG432R-style indexable turning insert manufactured from solid carbide and coated with TiC, TiCN, and TiN via a CVD process. The HC335 grade designation indicates a coated carbide formulation suited for steel and stainless steel turning applications. The insert features an 80-degree diamond shape, a right-hand cutting orientation, and a corner radius of 0.031 inches. The inscribed circle measures 0.5 inches and insert length is 0.508 inches (12.90 mm). These inserts are installed by machinists and CNC lathe operators in production and job-shop turning operations.

This insert is designed for external and internal turning operations on ferrous materials. The primary workpiece material designation is P (steel), with secondary suitability for M (stainless steel) applications. The G-style chip breaker geometry supports general-purpose turning at moderate feeds and depths of cut. The CNMG insert style is compatible with standard negative-rake CNMG toolholders that use clamp and pin holding methods. Typical applications include shaft turning, facing, and profiling on CNC and manual lathes in industrial and production environments.

Key Features

• HC335 grade solid carbide with CVD-applied TiC, TiCN, and TiN multilayer coating for wear resistance on steel and stainless
• 80-degree diamond insert shape (C) with negative clearance angle (N) for strong cutting edge geometry
• G-style chip breaker for controlled chip formation during general turning
• Right-hand cutting orientation; compatible with clamp and pin holding methods
• Tolerance code M for consistent dimensional accuracy across indexable positions
• Material grades C5 and C6 coverage for a broad range of cutting conditions

Compatibility

Designed for use in standard CNMG negative-rake turning toolholders that accept clamp and pin insert retention. Suitable for toolholder bores accepting a 0.203-inch (5.16 mm) insert hole diameter.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. The machine spindle must be stopped and all motion must have ceased before indexing or replacing any insert. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer when securing the insert. Inspect the toolholder pocket and seating surface for chips or damage before installing a new insert to ensure proper seating and edge repeatability.
