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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExternal threading configuration with right-hand cutting orientation\u003c\/li\u003e\n  \u003cli\u003eAccepts 22ER indexable threading inserts with 0.5 inch inscribed circle\u003c\/li\u003e\n  \u003cli\u003eScrew-clamping insert retention for secure, repeatable seating\u003c\/li\u003e\n  \u003cli\u003e1.25 x 1.25 inch square shank fits standard turret and gang tool blocks\u003c\/li\u003e\n  \u003cli\u003e7 inch overall length provides clearance for most lathe turret setups\u003c\/li\u003e\n  \u003cli\u003eHSER series style for consistent tool path geometry across multiple holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 22ER series indexable threading inserts.
