Carbide shims seat between the insert pocket and the indexable cutting insert, providing a stable, wear-resistant backing surface that protects the tool holder and maintains precise insert positioning. This shim follows the SM shim style with a negative rake geometry and neutral cutting direction, making it appropriate for standard external turning tool holders that use cylindrical insert shapes. Machinists and tooling technicians install this component during insert changes or when rebuilding worn tool holder pockets on CNC lathes and manual turning centers.\u003c\/p\u003e\u003cp\u003eThis shim is suited for external turning operations in production machining environments. It is dimensioned for indexable inserts with a 3\/8 inch inscribed circle and a thickness of 1\/8 inch (0.1250 inches). The SM shim style and negative rake configuration are common in heavy-duty roughing and general-purpose turning setups. The package quantity is 1 shim per unit, with a minimum order quantity of 5 units. This part is confirmed compatible with the A16RPTFNR11 complete tool holder.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSM shim style with negative rake and neutral cutting direction\u003c\/li\u003e\n\u003cli\u003eDesigned for cylindrical insert shapes with 3\/8 inch inscribed circle\u003c\/li\u003e\n\u003cli\u003eCarbide construction provides hardness and wear resistance at the insert seat\u003c\/li\u003e\n\u003cli\u003eThickness of 0.1250 inches for precise insert pocket depth control\u003c\/li\u003e\n\u003cli\u003eCompact dimensions: 0.55 inches length, 0.48 inches width, 0.13 inches height\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with the A16RPTFNR11 complete tool holder.

Ensure the machine spindle is fully stopped and the tool holder is removed from the turret or post before servicing the insert pocket. Inspect the shim seat and clamping screw for damage before seating the new shim. Do not overtighten the clamping screw, as carbide is brittle and can crack under uneven load.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: SM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Insert Shape\u003c\/strong\u003e: Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndexable Tool Type\u003c\/strong\u003e: External Turning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\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\u003eLength\u003c\/strong\u003e: 0.55 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.48 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.13 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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\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: 8000188\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51747537158450,"sku":"8000188","price":193.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0b5a2f462f6c808d6b15657a3e73c88a.jpg?v=1788882128","url":"https:\/\/voomisupply.com\/products\/hertel-8000188-carbide-shim-3-8-inch-ic-external-turning","provider":"Voomi Supply","version":"1.0","type":"link"}
