Hertel 1000184 Mtjn Indexable Turning Toolholder 3/4 Inch

Product Description

The HERTEL 1000184 is a right-hand MTJN-style negative rake indexable turning toolholder designed for use on CNC and manual lathes in production and job-shop turning operations. Built from steel with a 3/4 inch by 3/4 inch shank and an overall length of 4.5 inches, it provides a rigid, repeatable platform for external turning. The toolholder uses a clamp and screw insert-holding method to secure TN..43. series inserts, delivering consistent cutting geometry and fast insert changes. With a head length of 1.19 inches and a back-of-bar to cutting edge distance of 1.0 inch, it suits a wide range of turning center setups. Licensed machinists and CNC operators install this holder in standard turning tool blocks or gang-tool setups.

This toolholder is suited for external turning applications on lathes and turning centers in both residential shop and industrial production environments. The MTJN style with a 3-degree lead angle is commonly applied to straight turning and light facing operations. It accepts inserts with a 1/2 inch inscribed circle, making it compatible with a broad selection of triangular negative-rake inserts in the TN.. 432 complete insert family. It is a single-use, non-multi-tool holder and does not support coolant-through delivery.
