Built in the HSIR style, it accepts 11IR inserts secured by a screw-clamp holding method, providing repeatable positioning across indexing cycles. The toolholder features a 5\/8-inch (0.6250-inch decimal) shank diameter, a 5.5-inch overall length, and a minimum bore diameter of 0.5800 inches, making it suitable for threading bores in a range of workpiece diameters. Licensed machinists and CNC lathe operators working in job shop, production, or maintenance environments are the primary installers of this tool.\u003c\/p\u003e\u003cp\u003eThis toolholder is applied in internal threading operations where consistent thread form and insert repeatability are required. The HSIR series configuration is commonly used on CNC lathes and manual engine lathes equipped with tool turrets or boring bar holders. With a neck diameter of 0.5000 inches and a back-of-bar to cutting edge distance of 0.5800 inches, it is well suited for threading bores that require clearance between the shank body and the bore wall. The 0.3400-inch center-to-cutting-edge dimension supports precise thread positioning relative to the workpiece centerline.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eInternal, right-hand threading orientation in HSIR toolholder style\u003c\/li\u003e\n\u003cli\u003eAccepts 11IR threading inserts with 1\/4-inch inscribed circle via screw-clamp retention\u003c\/li\u003e\n\u003cli\u003e5\/8-inch shank diameter with 5.5-inch overall length for rigid reach into bores\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.5800 inches for threading smaller internal features\u003c\/li\u003e\n\u003cli\u003eNeck diameter of 0.5000 inches provides clearance in tight bore applications\u003c\/li\u003e\n\u003cli\u003eNo coolant-through design; standard external coolant application applies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with 11IR threading inserts having a 1\/4-inch inscribed circle.

Before mounting, confirm the machine is in an E-stop or locked-out state per your facility lockout-tagout procedure. Seat the shank fully in the toolholder block or turret station and torque the clamping screws to the machine or toolblock manufacturer specification. Verify insert seating and screw torque on the 11IR insert before initiating any cutting cycle.\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: HSIR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle Designation\u003c\/strong\u003e: HSIR-0500-5.5-11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HSIR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: 11IR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 1\/4 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 Diameter\u003c\/strong\u003e: 0.6250 inches (5\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.5 inches (5-1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.5800 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 0.5800 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.3400 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: 0.393 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: H08700197\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51735316660530,"sku":"H08700197","price":119.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/60a172b71db25c635431d87011b5c36a.jpg?v=1788771816","url":"https:\/\/voomisupply.com\/products\/hertel-h08700197-threading-toolholder-internal-rh-5-8","provider":"Voomi Supply","version":"1.0","type":"link"}
