Shims seat beneath the cutting insert to maintain proper insert height and positioning within the pocket, protecting the toolholder body from wear and damage caused by chip load and cutting forces. This shim is configured for negative rake geometry and a right-hand cutting direction, with a 0.5-inch inscribed circle dimension matching diamond-shaped inserts. It weighs approximately 0.02 pounds. Toolroom technicians and CNC machinists install this component as a precision seating element during insert changes or toolholder rebuilds.\u003c\/p\u003e\n\u003cp\u003eThis shim is intended for use in indexable turning applications on CNC lathes and manual turning centers. It is compatible with MCRNR and related toolholder styles in both left- and right-hand configurations. The ICSN shim style is a standard format commonly found in external turning holders used for roughing and finishing passes on a range of workpiece materials. Sold individually, with a minimum order quantity of 2 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eICSN shim style with negative rake geometry for compatibility with negative-rake insert systems\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction orientation\u003c\/li\u003e\n  \u003cli\u003e0.5-inch (0.5000 inch decimal) inscribed circle dimension for diamond-shaped inserts\u003c\/li\u003e\n  \u003cli\u003eProtects toolholder pocket from direct insert contact, extending holder service life\u003c\/li\u003e\n  \u003cli\u003eLightweight construction at 0.02 pounds for minimal mass addition to the tool assembly\u003c\/li\u003e\n  \u003cli\u003eCompatible with multiple MCLNR, MCLNL, MCKNR, and MCRNR series toolholder styles\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: A-MCLNR 20-4, MCKNR 16-4, MCLNL 12-4, MCLNL 16-4, MCLNR 12-4, MCLNR 16-4, and MCRNR 16-4.

Before replacing or seating the shim, ensure the machine is powered down, the spindle is locked, and all stored energy is released per your facility lockout\/tagout procedure. Verify the shim seats flat and fully within the insert pocket before torquing the clamp or insert screw. Do not use a damaged or deformed shim, as uneven seating can cause insert breakage or poor dimensional accuracy during cutting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Shim for Indexable Toolholders\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShim Style\u003c\/strong\u003e: ICSN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Shape\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle (Inch)\u003c\/strong\u003e: 0.5000 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: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style Compatibility\u003c\/strong\u003e: MCRNR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndexable Tool Type\u003c\/strong\u003e: Turning\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  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\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: 5599306\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51730773999922,"sku":"5599306","price":58.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5e8e09b4798fcc05aaa350e7436e2654.jpg?v=1788722641","url":"https:\/\/voomisupply.com\/products\/iscar-5599306-indexable-turning-shim-icsn-negative","provider":"Voomi Supply","version":"1.0","type":"link"}
