Hertel 1002830 Lh Mcln Negative Rake Turning Toolholder

Product Description

The HERTEL 1002830 is a left-hand MCLN-style indexable turning toolholder designed for negative rake external turning operations on CNC and manual lathes. It accepts CN..643 series inserts and features a square shank measuring 1.25 inches wide by 1.25 inches tall with an overall length of 6 inches. Weighing 1.19 pounds, this toolholder is built for rigidity and repeatable insert indexing in production turning environments. It is installed and serviced by machinists and CNC operators working in metal-cutting and general machining shops.

This toolholder is suited for external turning applications where a left-hand cutting orientation is required. The MCLN holder style positions the insert at a negative rake angle, which is appropriate for machining harder workpiece materials and interrupted cuts where insert strength and edge security are priorities. It is part of the HERTEL Multi-Option series and is intended for use in production and job-shop environments running standard turning centers and engine lathes.
