Hertel 1000194 Mvjn Indexable Turning Toolholder

Product Description

The HERTEL 1000194 is a right-hand MVJN-style indexable turning toolholder designed for external turning operations on CNC lathes and manual turning centers. Built with a 1 inch x 1 inch square steel shank and an overall length of 5 inches, it accepts VN..33. series inserts held in place by a clamp and screw insert-holding method. The negative rake geometry is suited for heavier interrupted cuts and harder workpiece materials where edge strength is critical. The 3-degree lead angle and 1.66-inch head length position the insert precisely for controlled chip flow and consistent depth of cut. This toolholder is used by machinists and CNC operators working in production turning environments.

This toolholder fits standard square-shank tool blocks and turrets sized for 1 inch x 1 inch shanks. It is part of the Multi-Option series and is intended for use with VN..332 complete insert configurations. Typical applications include roughing and semi-finishing passes on steel, cast iron, and similar machinable materials in job shop and production machine shop settings. The back-of-bar to cutting edge dimension is 1.25 inches, which assists in tool offset setup and turret positioning.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the turret is in a safe index position before mounting or removing the toolholder. Torque insert clamp screws to the insert manufacturer's recommendation using the appropriate Torx or hex key. Verify tool offset and cutting edge height at centerline before running the first part.
