Hertel 1000505 Turning Insert CNMG432R HC210 Carbide

Product Description

The HERTEL 1000505 is a CNMG432R-style indexable turning insert manufactured from solid carbide with a PVD-applied TiN coating and designated grade HC210. The insert features an 80-degree diamond shape (insert shape code C), a 0.5-inch inscribed circle, and a 1/32-inch (0.0312 inch) corner radius. At 12.90 mm (0.5079 inch) in length and 0.1875 inch thick, it is a right-hand insert held by clamp and pin. Tolerance code is M and clearance code is N. It is installed by machinists and CNC turning specialists on production and job-shop lathes requiring consistent, repeatable cutting geometry.

This insert is suited for turning operations on stainless steel (M), non-ferrous materials (N), and heat-resistant superalloys (S) as primary workpiece materials, with cast iron (K) as a secondary material group. The G chip breaker geometry supports controlled chip formation across a range of depths of cut and feed rates. Typical applications include external turning, facing, and profile operations in both production and maintenance machining environments. Material grades C2 and C4 apply to this insert per standard carbide grade classifications.

Key Features

• Solid carbide substrate with PVD TiN coating for wear resistance on a broad range of workpiece materials
• 80-degree diamond insert shape (CNMG style) provides two usable cutting edges per insert
• HC210 manufacturer grade suited for stainless steel, superalloys, and non-ferrous materials
• G chip breaker geometry for controlled chip evacuation at moderate feeds and depths
• Clamp and pin holding method for secure, repeatable insert indexing
• 0.0312-inch corner radius balances edge strength with surface finish requirements

Compatibility

Designed as a direct-fit replacement for CNMG432R-style insert pockets using clamp and pin holding; compatible with any toolholder accepting a CNMG 432 insert with a 0.2031-inch hole diameter and M tolerance.

Installation Notes

Indexable turning inserts must be installed and indexed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before changing or indexing inserts. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer — do not over-tighten the clamp screw or seat the insert with excessive force. Inspect the toolholder pocket for chips, wear, or damage before seating a new insert.
