Shims seat beneath the cutting insert to maintain precise pocket geometry, protect the toolholder body from wear, and ensure repeatable insert positioning during turning operations. This shim is compatible with diamond-shaped inserts and fits DCBNR\/L-style toolholder bodies. It supports both left-hand and right-hand cutting directions, making it a versatile service item for a CNC lathe or manual turning setup. The insert inscribed circle is 3\/8 inches (0.3750 inches decimal), which is the key dimension for confirming fitment to the correct pocket size. Installation is straightforward and requires no special tooling beyond standard insert-seating practices.\u003c\/p\u003e\n\u003cp\u003eThis shim is intended for use in metal-cutting turning applications where indexable insert toolholders are in service. It is appropriate for both production CNC environments and manual lathe work. The RCT shim style is matched to specific DCBN and DCLN toolholder families. Compatible complete toolholder models listed by the manufacturer include DCBNL 16-4, DCBNR 16-4, DCLNL 12-4, DCLNL 16-4, DCLNL 20-4, DCLNR 12-4, DCLNR 16-4, and DCLNR 20-4. Machinists and toolroom technicians typically keep replacement shims on hand as a standard maintenance item, since shim damage or wear can affect insert seating and surface finish quality.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRCT shim style matched to DCBNR\/L and DCLNR\/L indexable toolholder bodies\u003c\/li\u003e\n  \u003cli\u003eCompatible with diamond-shaped indexable inserts\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch (0.3750 inch) inscribed circle sizing for precise pocket fitment\u003c\/li\u003e\n  \u003cli\u003eSupports both left-hand and right-hand cutting directions\u003c\/li\u003e\n  \u003cli\u003eLightweight replacement component at 0.025 pounds for easy stocking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with the following complete toolholder models as specified by the manufacturer: DCBNL 16-4, DCBNR 16-4, DCLNL 12-4, DCLNL 16-4, DCLNL 20-4, DCLNR 12-4, DCLNR 16-4, and DCLNR 20-4.

Before servicing the toolholder, ensure the machine is powered down, the spindle is locked, and all motion has stopped. Remove the existing insert and clamp hardware, seat the replacement shim flat in the insert pocket, and reinstall the insert and clamping components according to the toolholder manufacturer's torque sequence. Do not reuse a shim that shows visible deformation, cracking, or seating surface damage.\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\u003eSeries\u003c\/strong\u003e: RCT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShim Style\u003c\/strong\u003e: RCT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndexable Tool Type\u003c\/strong\u003e: Turning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Shape\u003c\/strong\u003e: Diamond\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\u003eToolholder Style Compatibility\u003c\/strong\u003e: DCBNR\/L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle (mm)\u003c\/strong\u003e: 9.52 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.025 pounds\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: 2\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: 5505705\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51746955133234,"sku":"5505705","price":27.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/781553dc7fc057ee78b7a6cc10c76a6e.jpg?v=1788874903","url":"https:\/\/voomisupply.com\/products\/iscar-5505705-turning-shim-rct-3-8-inch-diamond-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
