It features a right-hand orientation and a square shank measuring 1.5 inches wide by 1.5 inches tall, with a shank length of 10.5 inches and an overall length of 12 inches. The toolholder accepts T 22 inserts secured by a screw-clamp holding method, providing rigid and repeatable insert positioning during threading passes. It is rated for a minimum bore diameter of 1.75 inches and carries a center-to-cutting-edge measurement of 0.98 inches. No coolant-through capability is present on this model. Licensed machinists and CNC turning specialists are the primary installers of this toolholder.\u003c\/p\u003e\u003cp\u003eThis toolholder is suited for internal threading on medium-to-large bore workpieces in both production and job-shop environments. The SIR series designation identifies it as a bar-style internal holder commonly mounted in square-shank pockets on tool turrets or gang-style tool posts. Applications include threading of hydraulic ports, pipe fittings, and other bored components requiring a minimum bore clearance of 1.75 inches. The screw-lock insert retention is appropriate for interrupted-cut conditions and materials that generate high cutting forces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eInternal threading application with right-hand cut direction\u003c\/li\u003e\n\u003cli\u003eSquare shank: 1.5 inches wide x 1.5 inches tall x 10.5 inches shank length\u003c\/li\u003e\n\u003cli\u003eOverall length of 12 inches for extended reach into deep bores\u003c\/li\u003e\n\u003cli\u003eAccepts T 22 inserts held by screw-clamp method for rigid, repeatable seating\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 1.75 inches suits medium-to-large bore threading\u003c\/li\u003e\n\u003cli\u003eOperates without coolant-through passages — standard external coolant only\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with T 22 inscribed-circle inserts in the ISCAR SIR series.

Secure the shank fully within the turret pocket or tool post, ensuring the shank seat surfaces are clean and free of chips before tightening. Power down and lock out the machine spindle before mounting or changing the toolholder or insert. Verify minimum bore clearance against the 1.75-inch minimum bore diameter specification before beginning a threading operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: SIR Series\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: T 22\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 10.5 inches\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: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.98 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Entry Style\u003c\/strong\u003e: Without Coolant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3800084\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51735287628082,"sku":"3800084","price":448.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/34a9878617cd2085b84c1f7ce7f2558b_5a73333c-6c97-40dc-a612-07388ac5c75a.jpg?v=1788771520","url":"https:\/\/voomisupply.com\/products\/iscar-3800084-indexable-threading-toolholder-internal-rh","provider":"Voomi Supply","version":"1.0","type":"link"}
