Hertel 1002851 Mvjn Indexable Turning Toolholder Rh

Product Description

The HERTEL 1002851 is a right-hand MVJN-style negative rake indexable turning toolholder designed for precision metal cutting on CNC and manual lathes. Built around a 1.25 inch by 1.25 inch square shank and measuring 6 inches in overall length, this toolholder accepts VN..332 series indexable inserts. The negative rake geometry promotes edge strength and thermal resistance during interrupted cuts and heavy material removal. It is intended for use by machinists and tool-and-die technicians working in production turning environments where consistent insert seating and rigid tool presentation are required.

This toolholder is suited for external turning operations on ferrous and non-ferrous workpieces in both job shop and production settings. The MVJN style positions the insert at a specific lead angle that is well matched to straight turning and light facing passes. The 1.25 inch square shank fits standard tool post bores commonly found on mid-size engine lathes and turning centers. It is part of the HERTEL Multi-Option series, which supports flexible insert selection across multiple grades and geometries within the VN..332 insert family.

Installation Notes

Installation should be performed by a qualified machinist familiar with indexable toolholder setup procedures. Secure all turret or tool post clamping screws to the machine manufacturer's specified torque before beginning cuts. Verify insert seating and clamp screw condition each time an insert is indexed or replaced. Never operate with a damaged clamp screw, worn insert pocket, or improperly seated insert, as this can result in insert ejection and workpiece or equipment damage.
