Hertel 1000111 Mdjn Turning Toolholder 1x1 Shank

Product Description

The HERTEL 1000111 is a right-hand MDJN-style negative rake indexable turning toolholder designed for precision metal-cutting operations on CNC and manual lathes. Built with a 1 x 1 inch square shank and an overall length of 6 inches, this toolholder accepts DN..33. series inserts secured by a clamp and screw holding method. The negative rake geometry promotes strength at the cutting edge, making it well suited for interrupted cuts and harder workpiece materials. Machined from steel, this holder is part of the HERTEL Multi-Option series and is intended for installation by machinists and CNC setup technicians in production and job-shop turning environments.

This toolholder is used in external turning applications on lathes where a right-hand cutting direction is required. The 3-degree lead angle suits general-purpose turning passes on ferrous and non-ferrous materials. With a 1.25 inch head length and a back-of-bar to cutting edge dimension of 1.25 inches, it positions the insert consistently for repeatable tool offsets. It is a straightforward drop-in setup for shops already running DN..33. insert inventory, reducing the number of insert grades and geometries that need to be stocked.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the lathe spindle is fully stopped and all machine power is locked out before mounting or removing the toolholder. Torque the insert clamp screw to the insert manufacturer's specification using a calibrated torque driver. Verify tool height and offset after seating the holder in the turret or tool post before resuming cuts.
