Hertel 1002807 Lh Mdjn Indexable Turning Toolholder

Product Description

The HERTEL 1002807 is a left-hand MDJN-style indexable turning toolholder designed for negative rake insert applications on CNC and manual lathes. It accepts DN..432 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, it is built for rigidity in turning operations where cutting forces demand a stable, close-tolerance toolholder body. This holder is part of the HERTEL Multi-Option Series and is intended for use by machinist trades in production and job-shop turning environments.

This toolholder is suited for external turning applications on lathes equipped to accept 1.25 inch by 1.25 inch shank tooling. The left-hand orientation positions the cutting edge for right-to-left feed direction, commonly used on specific turning configurations or gang-tooled setups. The negative rake geometry, combined with DN..432 insert compatibility, supports interrupted cuts and harder workpiece materials where edge strength is the priority. No insert is included; the toolholder requires a separate DN..432 insert selection based on workpiece material and depth of cut.

Installation Notes

Installation should be performed by qualified machinists familiar with indexable toolholder mounting procedures. Secure the shank in the tool post or turret to the full recommended engagement depth to maximize rigidity and minimize chatter. Ensure all machine motion is stopped and the spindle is locked before seating or indexing inserts. Confirm insert seating and screw torque per the insert manufacturer's specification before resuming cutting operations.
