Hertel 1000051 Lh Svjb Neutral Rake Indexable Toolholder

Product Description

The HERTEL 1000051 is a left-hand SVJB-style neutral rake indexable turning toolholder designed for precision external turning operations on CNC lathes and manual turning centers. Built on a screw-type insert holding method, it accepts VB..22. series inserts with a 0.25-inch inscribed circle diameter. The shank measures 0.5 inches wide by 0.5 inches tall with an overall length of 3.5 inches. The steel construction provides rigidity under interrupted cuts and continuous turning loads. Installed by machinists and toolroom technicians, this holder is suited for shops requiring reliable left-hand approach geometry on turning setups.

This toolholder is applied in turning operations where a left-hand cutting direction is required, such as facing toward the tailstock or back-turning applications. The neutral rake geometry makes it compatible with a range of insert grades for steel, stainless, and cast iron workpieces. The 3-degree lead angle and 0.625-inch back-of-bar to cutting edge dimension position the insert consistently for repeatable depth-of-cut control. It is a single-purpose, non-multi-use holder suited for dedicated turning station setups in production and job-shop environments.

Designed to accept VB..22. series indexable inserts, specifically VB.. 221, with a 0.25-inch inscribed circle. Fits standard 0.5 x 0.5 inch square-shank tool posts and turret blocks on CNC and manual lathes.

Installation Notes

Installation is performed by machinists or toolroom technicians during tool setup. Ensure the machine spindle is powered down and the turret or tool post is fully locked before changing or seating the holder. Use the appropriate torque driver for the insert clamping screw — do not overtighten, as this can damage the insert seat or screw thread. Verify insert seating and tool height alignment before resuming cutting operations.
