Built in the HSIR series, this right-hand toolholder accepts 16IR threading inserts secured by a screw-clamp holding method. The shank measures 0.75 inches in diameter and the tool runs 7 inches in overall length, making it suited for reaching into bores with a minimum diameter of 0.9 inches. The center-to-cutting-edge dimension is 0.51 inches. Machinists and tool-and-die technicians use this holder for producing internal threads in a range of workpiece materials and bore depths.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is configured for internal threading in production and job-shop turning environments. The HSIR-0750-7-16 style designation places it in applications requiring a 3\/4-inch round shank with a neck diameter matching the shank at 0.75 inches. The 0.9-inch minimum bore diameter and back-of-bar-to-cutting-edge distance of 0.9 inches define the practical reach envelope. No coolant-through feature is present, so external coolant delivery should be used when chip evacuation or heat management is required during threading cycles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInternal threading configuration with right-hand cut orientation\u003c\/li\u003e\n  \u003cli\u003eAccepts 16IR indexable threading inserts with screw-clamp retention\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch shank diameter for standard lathe toolpost and boring bar holder fitment\u003c\/li\u003e\n  \u003cli\u003e7-inch overall length provides reach for deeper bore applications\u003c\/li\u003e\n  \u003cli\u003e0.9-inch minimum bore diameter establishes the smallest workable bore size\u003c\/li\u003e\n  \u003cli\u003eHSIR series style designation for straightforward replacement and cross-referencing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to accept 16IR series threading inserts with a 3\/8-inch inscribed circle.

Ensure the machine spindle is fully stopped and the turret or toolpost is locked before changing or indexing inserts. Secure the shank in the boring bar holder to the tool manufacturer's recommended engagement depth and verify the insert is fully seated and the clamp screw is tightened before resuming cuts. Follow facility lockout\/tagout procedures before any tooling changeout on live equipment.\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: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HSIR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: HSIR-0750-7-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 0.9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.51 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: 16IR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\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: 0.393 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: H08700205\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51753548022066,"sku":"H08700205","price":128.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/32a582b500ee74741fc28ad836aa014c.jpg?v=1788938107","url":"https:\/\/voomisupply.com\/products\/hertel-h08700205-threading-toolholder-internal-right-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
