Hertel 1002829 Lh Mcln Indexable Turning Toolholder

Product Description

The HERTEL 1002829 is a left-hand MCLN-style indexable turning toolholder designed for negative-rake insert geometries. It accepts CN..543 series inserts and is built for use on manual and CNC turning lathes in production and job-shop environments. The shank measures 1-1/4 inches wide by 1-1/4 inches tall with an overall length of 6 inches, providing a rigid platform for interrupted and continuous turning operations. Machinists and tool crib personnel in metalworking facilities specify this holder for its compatibility with widely available CN..543 inserts and its left-hand orientation, which suits specific tooling setups and turret positions.

This toolholder fits standard turning center and engine lathe applications where a left-hand MCLN holder is required. It is suited to external turning operations on ferrous and non-ferrous materials when paired with the appropriate CN..543 insert grade. The Multi-Option series designation indicates compatibility across common turret and quick-change toolpost setups that accept a 1-1/4 inch square shank. It is not a multi-use tool and is intended as a dedicated turning application holder. Machine shops running production turning programs or maintenance facilities needing a reliable indexable holder will find this a direct-fit solution.

Installation Notes

Installation should be performed by a qualified machinist or tooling specialist. Power down and lock out the machine spindle before changing toolholders or inserts.
