Built to the HSER series style, this right-hand toolholder accepts 27ER threading inserts secured by a screw-clamp holding method, providing repeatable insert positioning and reliable cutting edge engagement. The shank measures 1.25 x 1.25 inches square with an overall length of 7 inches, making it suited for standard-size lathe tool stations. Weighing 1.72 pounds, this is a solid, production-grade holder intended for use by machinists and toolroom professionals in metal-cutting environments.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is used in external threading applications on manual or CNC lathes where consistent thread form accuracy is required. The HSER series is a common style on production floors handling a range of thread forms using indexable 27ER inserts. It is appropriate for both job shop and production turning environments where a 1-1\/4 inch square shank tool station is present. Coolant-through capability is not included in this holder, so external coolant application or dry cutting conditions apply.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExternal threading operation with right-hand cutting orientation\u003c\/li\u003e\n  \u003cli\u003eAccepts 27ER indexable threading inserts with 5\/8 inch inscribed circle\u003c\/li\u003e\n  \u003cli\u003eScrew-clamp insert holding method for secure, repeatable seating\u003c\/li\u003e\n  \u003cli\u003e1.25 x 1.25 inch square shank fits standard lathe tool blocks and turrets\u003c\/li\u003e\n  \u003cli\u003e7 inch overall length suits typical CNC and manual lathe setups\u003c\/li\u003e\n  \u003cli\u003eHSER-1250-7-27 style designation for straightforward replacement and ordering\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 27ER series indexable threading inserts.
