Built with a 1 x 1 inch square shank and a 6 inch overall length, it uses a clamp-style insert holding method and is compatible with NU 3125R inserts. The toolholder is intended for machinists and tool-room professionals who require precise thread-form geometry on a variety of workpiece materials. Its square shank profile and robust clamping mechanism provide the rigidity needed for consistent threading passes.\u003c\/p\u003e\n\u003cp\u003eThis toolholder suits production turning applications in job shops and manufacturing facilities where repeatable threading performance is required. The left-hand orientation is selected when spindle direction or workpiece setup demands reversed cutting engagement. It is appropriate for use on manual and CNC lathes handling standard and specialty thread forms. The Top Notch series is a well-established platform for indexable threading, making the 1097253 a direct-fit choice when rebuilding or expanding a threading toolholder inventory.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHandles both internal and external threading with a single toolholder style\u003c\/li\u003e\n  \u003cli\u003eLeft-hand cutting orientation for reverse-spindle or specific workholding setups\u003c\/li\u003e\n  \u003cli\u003e1 x 1 inch square shank for positive, rigid machine interface\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert retention accepts NU 3125R inserts\u003c\/li\u003e\n  \u003cli\u003e6 inch overall length with a 1.25 inch head length for reach and clearance\u003c\/li\u003e\n  \u003cli\u003ePart of the Top Notch series for broad insert and accessory ecosystem compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with NU 3125R indexable threading inserts within the KENNAMETAL Top Notch toolholder platform.
