The toolholder accepts N.2L inserts secured by a clamp-style holding method, providing rigid, repeatable insert positioning during interrupted and continuous thread-cutting passes. The shank measures 0.75 x 0.75 inches (19.05 x 19.05 mm) with an overall length of 4.5 inches. A head length of 0.5 inches and a maximum depth of cut of 0.138 inches make this holder well suited for precision threading work where controlled engagement is critical. Licensed machinists, CNC lathe operators, and tool-crib technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis toolholder fits standard 0.75-inch square-shank tool blocks and turret positions on CNC and manual turning centers. It is rated for both grooving and threading applications, making it a multi-use holder that reduces the number of dedicated tools needed in a setup. The Top Notch series is a recognized platform for indexable grooving and threading, and this holder is configured for right-hand cutting direction. Back-of-bar to cutting-edge distance is 1.0 inch, which informs boring-bar clearance calculations when used for internal threading work.\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 body\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting configuration for standard lathe and turning-center setups\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert retention for secure N.2L insert seating under cutting loads\u003c\/li\u003e\n  \u003cli\u003e0.75 x 0.75 inch square shank fits standard tool blocks and turret stations\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.138 inches supports controlled thread-form engagement\u003c\/li\u003e\n  \u003cli\u003eMulti-use designation reduces dedicated tooling inventory requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with N.2L indexable inserts in the Top Notch series platform.

Seat the shank fully in the tool block or turret pocket and torque the clamping screws to the machine or block manufacturer's specification. Verify insert seating and clamp integrity before resuming cutting operations. For internal threading applications, confirm adequate bore clearance against the 1.0-inch back-of-bar to cutting-edge dimension before engaging the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal and External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: NE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: N.2L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Width and Height\u003c\/strong\u003e: 0.75 x 0.75 inches (19.05 x 19.05 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches (114.30 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 0.5 inches (12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.138 inches (3.51 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 1.0 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Tool Application\u003c\/strong\u003e: Grooving and Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-use Tool\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.69 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1097559\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51746250686770,"sku":"1097559","price":202.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3cfa085b99f9dff0618177e8559866bd.jpg?v=1788867648","url":"https:\/\/voomisupply.com\/products\/kennametal-1097559-threading-toolholder-0-75-in-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
