Hertel 1002805 Mdjn Negative Rake Turning Toolholder

Product Description

The HERTEL 1002805 is a right-hand MDJN-style indexable turning toolholder designed for negative rake cutting operations on CNC lathes and manual turning centers. It features a 1 inch by 1 inch shank cross-section and an overall length of 5 inches, providing rigid tool support for external turning and facing operations. The toolholder accepts DN..432 series inserts, which are commonly used in general-purpose turning of steel, cast iron, and similar materials. This toolholder is intended for installation and use by machinists and CNC lathe operators in production and job-shop environments.

The HERTEL 1002805 is suited for external turning applications in both production and low-volume machining environments. Its MDJN configuration positions the insert at a negative rake angle, promoting edge strength and predictable cutting performance on ferrous and harder workpiece materials. The 1 inch by 1 inch shank fits standard tool post and turret pockets sized for that cross-section, making it a straightforward drop-in for shops already running compatible setups. This is a single-use, non-multi-purpose toolholder from the Multi-Option series.

Installation Notes

Installation should be performed by a qualified machinist with the machine powered down and in a locked-out, tagged-out state before toolholder changeout. Secure the shank fully within the tool post or turret pocket to the depth recommended by the machine manufacturer before tightening clamp bolts. Verify insert seating and clamp torque before resuming cutting operations. Follow all applicable shop safety protocols and machine manufacturer guidelines.
