It accepts N.3L inserts secured by a clamp-style holding method, providing stable, repeatable positioning during interrupted and continuous cuts. The shank measures 1 inch wide by 1 inch tall (25.4 x 25.4 mm) with an overall length of 6 inches (152.4 mm). Rated for a maximum depth of cut of 0.21 inches (5.33 mm), this toolholder suits machinists and toolroom professionals working in production or job-shop environments.\u003c\/p\u003e\u003cp\u003eThis toolholder is built for external threading and grooving applications on metal lathes and CNC turning equipment. The left-hand orientation positions the cutting edge for specific spindle-direction and part-geometry requirements. The Top Notch series is a widely recognized platform in indexable grooving and threading, making the 1097260 a practical replacement or additional holder for shops already running compatible Top Notch insert inventory. Head length is 1.25 inches (31.75 mm) and the center-to-cutting-edge distance is 0.5 inches, supporting accurate tool-height setup at spindle centerline.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eExternal threading and grooving capability in a single toolholder platform\u003c\/li\u003e\n\u003cli\u003eLeft-hand cutting orientation for reverse-spindle or specific geometry applications\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding for secure, repeatable N.3L insert seating\u003c\/li\u003e\n\u003cli\u003e1 inch x 1 inch shank cross-section for compatibility with standard tool-block and turret positions\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.21 inches (5.33 mm) suits a wide range of thread and groove profiles\u003c\/li\u003e\n\u003cli\u003eMulti-use design rated for both grooving and threading operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with N.3L Top Notch series indexable inserts.

Before mounting or changing inserts, ensure the machine spindle is fully stopped and locked out per your facility lockout\/tagout procedure. Secure the shank in the turret or tool block to the tool-block manufacturer's specified clamping procedure, and verify the cutting edge is set at spindle centerline before beginning cuts. Inspect the clamp and insert seat for chips or debris each time an insert is indexed or replaced.\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.3L\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: 1 inch (25.4 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 1 inch (25.4 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches (152.4 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.25 inches (31.75 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.21 inches (5.33 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 1.25 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: 1.68 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: 1097260\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51755924914482,"sku":"1097260","price":208.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/56b75b6175fe4f1ba502d68817bcf238.jpg?v=1788961679","url":"https:\/\/voomisupply.com\/products\/kennametal-1097260-threading-toolholder-external-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
