Hertel 1000054 Svjb Indexable Turning Toolholder

Product Description

The HERTEL 1000054 is a right-hand SVJB-style neutral rake indexable turning toolholder designed for precision external turning operations on CNC and manual lathes. The toolholder features a 0.625-inch by 0.625-inch square shank and an overall length of 4 inches, making it well suited for close-tolerance turning applications. It uses a screw-type insert clamping method, providing secure insert retention during interrupted and continuous cuts. The back of bar to cutting edge dimension is 0.75 inches. This holder is intended for installation and use by machinists, toolroom technicians, and CNC setup professionals in production and job-shop environments.

The 1000054 is designed for use in external turning applications where a right-hand, neutral rake geometry is required. It is compatible with VB..22. series inserts, specifically the VB.. 221 complete insert designation, with an inscribed circle of 0.25 inches. The SVJB style with a 3-degree lead angle suits general-purpose turning on steel, cast iron, and similar materials. Typical applications include shaft turning, facing, and light profiling on standard CNC turning centers and engine lathes.
