It features an IRSN shim style with a negative rake and neutral cutting direction, making it suitable for standard OD turning operations where consistent insert seating is required. The shim measures 3\/4 inch inscribed circle and 3\/16 inch (0.1875 inch) thickness, providing a stable, precision foundation for cylindrical inserts in compatible tool holders. At 0.02 pounds, it is a lightweight component that plays a critical role in maintaining insert alignment and protecting the tool holder pocket from wear and damage. Installation is performed by machinists and tooling technicians as part of routine insert or holder maintenance.\u003c\/p\u003e\n\u003cp\u003eThis shim is intended for external turning setups in CNC and manual lathe environments. It is sized for cylindrical insert shapes and works within tooling systems that require a negative rake shim seat. Typical applications include OD roughing and finishing passes where insert security and holder longevity are priorities. The IRSN designation indicates compatibility with specific holder pocket geometries found in production turning operations across light and medium machining environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbide shim construction for hardness and wear resistance in high-cycle turning applications\u003c\/li\u003e\n  \u003cli\u003eIRSN shim style with negative rake and neutral cutting direction\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch (0.7500 inch) inscribed circle sized for cylindrical indexable inserts\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch (0.1875 inch) thickness provides consistent insert pocket depth\u003c\/li\u003e\n  \u003cli\u003eDesigned for external turning tool holder applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with tool holder A16RPTFNR11.

Power down and lock out the machine spindle before removing or replacing any shim, insert, or holder component. Use the appropriate torque wrench and insert screw per the tool holder manufacturer specifications when reassembling the insert clamping system. Inspect the holder pocket for damage or debris before seating the shim to ensure proper insert support and alignment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Carbide Shim\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShim Style\u003c\/strong\u003e: IRSN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndexable Tool Type\u003c\/strong\u003e: External Turning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Shape\u003c\/strong\u003e: Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 3\/4 inch (0.7500 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle (mm)\u003c\/strong\u003e: 19.05 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3\/16 inch (0.1875 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.19 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.74 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.74 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Tool Holder\u003c\/strong\u003e: A16RPTFNR11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: 8000168\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730404639026,"sku":"8000168","price":904.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/21fdfa749a2c58720938bd8dc51c4093.jpg?v=1788716881","url":"https:\/\/voomisupply.com\/products\/hertel-8000168-indexable-shim-3-4-in-irsn-external-turning","provider":"Voomi Supply","version":"1.0","type":"link"}
