Hertel 1000207 Mwln Indexable Turning Toolholder

Product Description

The HERTEL 1000207 is a right-hand MWLN-style indexable turning toolholder designed for external turning operations on manual and CNC lathes. It features a negative 5-degree rake angle and accepts WN..33. series inserts secured by a clamp and screw holding method. The shank measures 1 inch wide by 1 inch tall with an overall length of 6 inches, making it a standard-profile holder suited for general-purpose turning. Constructed from steel, this toolholder is built for repeated use in production environments. It is installed and used by machinists and CNC lathe operators working in metal cutting applications.

This toolholder is intended for external turning applications in both job shop and production machining environments. The MWLN style and 5-degree lead angle make it well-suited for straight and facing cuts on a variety of workpiece materials. The 1-inch square shank fits standard lathe tool posts commonly found in mid-size turning centers and manual lathes. The back-of-bar to cutting edge dimension of 1.25 inches provides consistent tool centerline positioning during setup.
