The holder features a 1.25 x 1.25 inch square shank and an overall length of 6 inches, making it a rigid, machine-ready solution for precision thread cutting. It accepts N.4R inserts secured by a clamp-style holding method, providing repeatable insert positioning across high-volume production runs. Machinists and CNC toolroom technicians are the primary installers of this toolholder.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is suited for threading and grooving applications in metalworking environments, including job shops, production turning cells, and maintenance machining operations. It handles both internal and external thread profiles from a single holder setup, reducing tool changes and setup time. With a maximum depth of cut of 0.294 inches and a head length of 0.75 inches, the 1097240 fits typical turning center tool turrets where square-shank tooling is specified. It is a multi-use tool appropriate for a range of ferrous and non-ferrous workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHandles both internal and external threading and grooving from a single holder\u003c\/li\u003e\n  \u003cli\u003eLeft Hand orientation for use on machines and setups requiring LH tooling\u003c\/li\u003e\n  \u003cli\u003e1.25 x 1.25 inch square shank for rigid, low-deflection mounting\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert holding for secure, repeatable N.4R insert indexing\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.294 inches suits standard threading pass depths\u003c\/li\u003e\n  \u003cli\u003eTop Notch series tooling designed for consistent insert-to-holder fit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with N.4R series indexable threading inserts in standard square-shank tool turret positions requiring a 1.25 x 1.25 inch Left Hand toolholder.
