Hertel 1000199 Mvjn Negative Rake Turning Toolholder

Product Description

The HERTEL 1000199 is a right-hand MVJN-style negative rake indexable turning toolholder designed for use on CNC and manual lathes in metal-cutting operations. Built from steel, it features a 1 x 1 inch square shank and an overall length of 6 inches. The toolholder uses a clamp-and-screw insert holding method to secure VN..43-series inserts with a 0.5-inch inscribed circle. Negative rake geometry suits heavy interrupted cuts and harder workpiece materials. Licensed machinists and CNC setup technicians are the primary installers of this toolholder in production and job-shop turning applications.

This toolholder fits standard OD turning applications on lathes with a tool post or turret that accepts a 1 x 1 inch shank. The 3-degree lead angle and MVJN pocket geometry position the insert for general-purpose external turning. It is suited for both roughing and finishing passes when paired with the correct VN..43-series insert grade and geometry. The back-of-bar to cutting edge dimension is 1.25 inches, allowing predictable centerline setup. No coolant-through capability is provided, so external coolant delivery must be used when flood or mist cooling is required.

Installation Notes

Installation is performed by machinists or CNC setup technicians. Before mounting or changing inserts, ensure the lathe is powered down, the spindle is locked, and all moving parts have come to a complete stop. Seat the shank fully in the tool post or turret and torque the clamping screws per the machine tool manufacturer's specifications. Handle indexable inserts with care — edges are sharp and can cause injury during handling and installation.
