Built to the Top Notch series standard, it accepts N.2L inserts secured with a clamp-style holding method, providing rigid insert positioning during interrupted and continuous threading passes. The square shank measures 0.75 x 0.75 inches with an overall length of 4.5 inches. Maximum depth of cut is 0.138 inches, making it well suited for standard external thread profiles. This toolholder is installed and serviced by machinists, toolroom technicians, and CNC operators working in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThe 1097254 is applied to external threading and grooving operations on outside diameters where a left-hand holder orientation is required by the machine setup or part geometry. The Top Notch series toolholder platform is a common choice for shops running high-mix turning work that demands quick insert indexing without sacrificing repeatability. The clamp-style insert retention keeps the N.2L insert stable under moderate feed rates and varying material conditions. Typical applications include threading carbon steel, alloy steel, aluminum, and stainless on bar-fed and chuck-style turning machines.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eExternal thread type with left-hand holder orientation for correct tool path alignment\u003c\/li\u003e\n\u003cli\u003eAccepts N.2L inserts with clamp-style holding for secure, repeatable insert seating\u003c\/li\u003e\n\u003cli\u003eTop Notch series toolholder style (NS) for compatibility within the Top Notch platform\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.138 inches suitable for standard external thread profiles\u003c\/li\u003e\n\u003cli\u003eBack-of-bar to cutting edge distance of 1.0 inch with center-to-cutting-edge offset of 0.35 inches\u003c\/li\u003e\n\u003cli\u003eMulti-use design supports both threading and grooving applications from a single holder\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with N.2L Top Notch series inserts on external threading and grooving applications.

Before mounting, ensure the machine spindle is fully stopped, the turret is in the tool-change position, and all energy is locked out per established LOTO procedures. Seat the shank fully into the tool block or turret pocket and torque clamping screws evenly to the machine manufacturer's specification. Verify insert seating and confirm the cutting edge height and offset dimensions against the part program before initiating a cutting pass.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: NS\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\/Diameter\u003c\/strong\u003e: 0.75 inches (19.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 0.75 inches (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: 0.75 inches (19.05 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\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.35 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Tool Application\u003c\/strong\u003e: Grooving, Threading\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-use Tool\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.71 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 1097254\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732989247794,"sku":"1097254","price":194.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5d46820fc424c5f9050e7e9047cfa25d.jpg?v=1788750094","url":"https:\/\/voomisupply.com\/products\/kennametal-1097254-indexable-threading-toolholder-0-75in","provider":"Voomi Supply","version":"1.0","type":"link"}
