Hertel H08700122 Threading Toolholder 1.25 Inch Shank

Product Description

The HERTEL H08700122 is an external, right-hand indexable threading toolholder designed for precision thread-turning operations on CNC lathes and turning centers. Built to the HSER series style, it accepts 22ER inserts secured by a screw-clamping method, providing repeatable insert positioning during high-volume threading cycles. The shank measures 1.25 inches wide by 1.25 inches tall with an overall length of 7 inches. This toolholder is suited for machinists and tool-room technicians working external threading applications where consistent geometry and rigid clamping are required.

The H08700122 is used in external threading operations on ferrous and non-ferrous workpieces across job shop, production, and maintenance machining environments. Its HSER-1250-7-22 style designation indicates direct compatibility with standard 22ER threading inserts with a 0.5 inch inscribed circle. This toolholder fits square-shank tool blocks and holders common to gang tooling and turret lathe setups. It is appropriate for both production threading and single-piece work where a rigid, repeatable external thread form is needed.
