Hertel 1000193 Lh Mvjn Indexable Turning Toolholder

Product Description

The HERTEL 1000193 is a left-hand MVJN-style indexable turning toolholder designed for negative rake turning applications on CNC and manual lathes. It features a 1 inch by 1 inch square shank with an overall length of 5 inches and a head length of 1.66 inches. The toolholder uses a clamp and screw insert holding method and accepts VN..33. series inserts with a 3/8 inch inscribed circle. Constructed from steel, it delivers the rigidity needed for interrupted cuts and heavy stock removal on production turning operations. Licensed machinists and CNC operators working in job shop or production environments are the primary users.

This toolholder is suited for external turning operations requiring a left-hand cutting direction with a 3-degree lead angle. The MVJN style positions the insert at a negative rake angle, which increases cutting edge strength and is well matched to cast iron, hardened steel, and other difficult-to-machine materials. It fits standard OD turning setups on lathes with tool posts or turrets that accommodate a 1 inch square shank. The back of bar to cutting edge dimension is 1.25 inches, which governs centerline offset during setup.

Key Features

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine before mounting or changing the toolholder or insert. Confirm shank seating and torque the clamp screw to the insert manufacturer specification using calibrated tooling. Verify cutting edge centerline height against spindle centerline before taking a first cut, using the 1.25 inch back-of-bar-to-cutting-edge dimension as a reference during setup.
