It accepts N.4L inserts held in place by a clamp-style insert holding method and is rated for both grooving and threading operations. The square shank measures 1.25 x 1.25 inches with an overall length of 6 inches, giving machinists a rigid, predictable setup on CNC lathes and manual turning centers. Maximum depth of cut is 0.294 inches. This toolholder is installed by machinists and toolroom technicians working in production turning or job-shop environments.\u003c\/p\u003e\u003cp\u003eThe 1097264 is suited for external threading and grooving applications on turning equipment where a left-hand toolholder is required. The Top Notch series is designed for consistent insert indexing, making it a practical choice for high-volume threading operations as well as single-part setups. The multi-use designation means it handles both threading and grooving without a change in toolholder, reducing setup time between operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eExternal, left-hand cutting geometry for threading and grooving operations\u003c\/li\u003e\n\u003cli\u003eTop Notch series with clamp-style insert retention for repeatable insert positioning\u003c\/li\u003e\n\u003cli\u003eCompatible with N.4L indexable inserts\u003c\/li\u003e\n\u003cli\u003e1.25 x 1.25 inch square shank for rigid setup in standard tool blocks\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.294 inches\u003c\/li\u003e\n\u003cli\u003eMulti-use design supports both grooving and threading without toolholder change\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with N.4L series Top Notch indexable inserts.
