Hertel 1002043 Cnmg 432-LR HC1250T Turning Insert

Product Description

The HERTEL 1002043 is a CNMG 432-LR style turning insert manufactured from solid carbide with a CVD-applied HC1250T coating. It features an 80-degree diamond insert shape with a neutral cutting direction, making it a multi-tipped indexable insert designed for negative rake angle turning operations. The inscribed circle measures 0.5 inches, corner radius is 0.0315 inches (1/32 inch nominal), and insert thickness is 0.1874 inches (3/16 inch nominal). Insert length is 0.5 inches (12.70 mm). This insert is intended for use by machinists and CNC lathe operators performing external and internal turning on ISO material group P workpiece materials.

The 1002043 is suited for general turning applications on steel and similar ferrous workpiece materials classified under ISO material group P. The lever lock holding method and CNMG geometry are compatible with standard CNMG toolholders commonly used in production CNC turning centers and manual lathes. The G-style chip breaker geometry supports controlled chip evacuation during moderate to medium-depth turning passes, with a maximum depth of cut of 0.2165 inches (5.50 mm). This insert is packaged individually and sold in minimum order quantities of 10 units.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the turret or toolpost is de-energized before indexing or replacing inserts. Use the appropriate torx or hex key for the lever lock clamping screw and confirm the insert seats flush in the pocket before resuming cutting operations. Do not exceed the maximum depth of cut rating for the insert geometry.
