Part of the KENNAMETAL LT Threading series, it accepts LT 16EL inserts held in place by a clamp-style insert holding method. The shank measures 1 x 1 inches in cross-section with an overall length of 6 inches, providing a rigid platform for consistent thread geometry. The toolholder weighs 1.72 pounds and is suited for machinists and tool-and-die professionals requiring reliable, repeatable external threading performance.\u003c\/p\u003e\u003cp\u003eThis toolholder is configured for external threading applications where a left-hand cutting orientation is required. The LSS toolholder style and 3\/8-inch insert inscribed circle make it compatible with standard LT 16EL threading inserts. Typical use cases include production threading on OD surfaces in general machining shops, aerospace component manufacturing, and heavy-duty fabrication environments. The 1 x 1 inch shank fits standard tool post and turret positions commonly found in medium-sized lathes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eExternal, left-hand threading orientation for OD thread-cutting applications\u003c\/li\u003e\n\u003cli\u003eLSS toolholder style with clamp-style insert retention for secure, repeatable insert positioning\u003c\/li\u003e\n\u003cli\u003eAccepts LT 16EL indexable threading inserts with a 3\/8-inch inscribed circle\u003c\/li\u003e\n\u003cli\u003e1 x 1 inch square shank with 6-inch overall length for rigid tool setup\u003c\/li\u003e\n\u003cli\u003eNo coolant-through design; single-use tool configuration\u003c\/li\u003e\n\u003cli\u003ePart of the KENNAMETAL LT Threading series for standardized insert management\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with LT 16EL indexable threading inserts.

Power down and lock out the machine before mounting or removing the toolholder. Ensure the shank seating surfaces and turret bore are clean and free of chips before tightening. Follow the machine tool manufacturer's recommended clamping torque procedures for square-shank toolholders; do not exceed the tool post or turret manufacturer's specified holding capacity.\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\u003eToolholder Style\u003c\/strong\u003e: LSS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: LT 16EL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Width\/Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1 inch\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.72 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: 1281813\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51755169153330,"sku":"1281813","price":236.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f0e1eaeab5e6d2b759fce1f45d1f6de0.jpg?v=1788951774","url":"https:\/\/voomisupply.com\/products\/kennametal-1281813-threading-toolholder-external-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
