Hertel 1000209 Mwln Indexable Turning Toolholder

Product Description

The HERTEL 1000209 is a right-hand MWLN-style indexable turning toolholder designed for general-purpose external turning operations on CNC and manual lathes. It features a negative rake angle of -5 degrees, which increases cutting edge strength and is well suited for heavy interrupted cuts and tough workpiece materials. The square shank measures 1.25 inches wide by 1.25 inches tall and the overall length is 6 inches. The toolholder accepts WN..43. series inserts, held securely by a clamp and screw method. It is constructed from steel for durability under continuous production conditions and is part of the Multi-Option series.

This toolholder is intended for use in production turning environments where a rigid, negative-rake geometry is preferred. It fits standard lathe tool posts and turrets sized for a 1-1/4 inch square shank. The back-of-bar to cutting edge distance is 1.5 inches, and the insert inscribed circle is 0.5 inches. Typical applications include roughing and semi-finishing passes on ferrous and non-ferrous metals in both job shop and production settings. Installation is performed by qualified machinists or tooling technicians.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician.
