Shims seat beneath the cutting insert in the pocket of the toolholder, maintaining correct insert height, protecting the toolholder body from cutting forces, and ensuring repeatable positioning when inserts are indexed or replaced. This shim is sized for a 12 mm inscribed circle (0.472 inch) cylindrical insert and supports both left-hand and right-hand cutting directions. It is a precision replacement component used by machinists and tooling technicians in production turning operations on CNC and manual lathes.\u003c\/p\u003e\n\u003cp\u003eThis shim is specified for use in SRGCR\/L-style turning toolholders across multiple mounting configurations. It is suited for shop environments running high-volume turning operations where insert pocket integrity must be maintained over many tool changes. The TRC series shim is a direct-replacement component for the listed compatible holders, including both standard and modular shank configurations. Purchasing the correct shim is critical to preserving insert seating accuracy and preventing pocket damage over time.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTRC shim style sized for 12 mm inscribed circle cylindrical inserts\u003c\/li\u003e\n  \u003cli\u003eSupports left-hand and right-hand cutting directions\u003c\/li\u003e\n  \u003cli\u003eCompatible with SRGCR\/L toolholder style family\u003c\/li\u003e\n  \u003cli\u003eProtects toolholder pocket from direct insert contact during cutting\u003c\/li\u003e\n  \u003cli\u003eMaintains consistent insert height for repeatable tool offsets\u003c\/li\u003e\n  \u003cli\u003eSold individually, minimum order quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with the following complete toolholders as specified by the manufacturer: C5 SRDCN-00060-12, C5 SRGCL-35060-12, C5 SRGCR-35060-12, C6 SRGCR-45065-12-JHP, IM50 SRGCL-12, IM50 SRGCR-12, SRDCN 2525M-12, SRDCN 3225P-12, SRGCL 2525M-12, SRGCR 2525M-12, and SRGCR 2525M-12-JHP.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eShim replacement is performed by tooling technicians or machinists during insert indexing or toolholder maintenance. Before servicing the toolholder, ensure the machine spindle is fully stopped and the toolholder is removed from the turret or tool block. Verify the replacement shim part number against the toolholder documentation before installation to confirm correct fit. Improper or missing shims can cause insert rocking, poor surface finish, or accelerated pocket wear.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Shim\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShim Style\u003c\/strong\u003e: TRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Shape\u003c\/strong\u003e: Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 12.00 mm (0.4720 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style Compatibility\u003c\/strong\u003e: SRGCR\/L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Left Hand, Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndexable Tool Type\u003c\/strong\u003e: Turning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5520078\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51738409337138,"sku":"5520078","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3cd52e2eea7c28cd19361f76c32b6953.jpg?v=1788799177","url":"https:\/\/voomisupply.com\/products\/iscar-5520078-indexable-insert-shim-trc-12-mm-turning","provider":"Voomi Supply","version":"1.0","type":"link"}
