Built in the Flo-Lock series, this left-hand toolholder features a 1 x 1 inch square shank and a 12-inch overall length. It accepts FL 3R inserts held in place by a clamp-style insert holding method. The minimum bore diameter of 1.375 inches and a center-to-cutting-edge dimension of 0.688 inches define its reach into bored or pre-drilled workpieces. Coolant-through capability supports chip evacuation and heat management during continuous threading passes.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is suited for internal threading and grooving applications in production and job-shop turning environments. The left-hand configuration is used where spindle rotation or workpiece orientation requires a tool that cuts on the opposite side from a standard right-hand holder. The multi-use designation means a single holder can be repositioned for both threading and grooving with compatible FL 3R inserts, reducing tooling inventory requirements. Machinists and CNC operators working with ferrous and non-ferrous materials in bore diameters starting at 1.375 inches will find this holder appropriate for their setup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInternal threading and grooving capability in a single Flo-Lock series toolholder\u003c\/li\u003e\n  \u003cli\u003eLeft-hand orientation for reverse-rotation or specific fixturing setups\u003c\/li\u003e\n  \u003cli\u003e1 x 1 inch square shank with 12-inch overall length for extended reach\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design aids chip removal and extends insert life\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert retention for secure, repeatable FL 3R insert indexing\u003c\/li\u003e\n  \u003cli\u003eMinimum bore diameter of 1.375 inches suits medium to large bore applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with FL 3R series inserts.

The machine should be fully powered down and locked out before mounting or removing any toolholder. Ensure the tool post or turret bore is clean and free of burrs before seating the shank. Verify coolant-through passages are clear and connected before running the first pass.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Width and Height\u003c\/strong\u003e: 1 inch x 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.688 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: FL 3R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: A16\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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-use Tool\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Flo-Lock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.66 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: TOOL-FLO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 96401616\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TOOL-FLO","offers":[{"title":"Default Title","offer_id":67912082194738,"sku":"96401616","price":372.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ddb86d5b2719f6f828cb4c5153b69de2.jpg?v=1791226725","url":"https:\/\/voomisupply.com\/products\/tool-flo-96401616-indexable-threading-toolholder-1x1-in","provider":"Voomi Supply","version":"1.0","type":"link"}
