Shims seat beneath the cutting insert to maintain proper cutting edge height, protect the toolholder pocket from wear, and provide a stable seating surface when inserts are indexed or replaced. This shim follows the IVSN style and is sized for a 3\/8 inch (0.3750 inch decimal) inscribed circle. It is compatible with diamond-shaped inserts. Installation is performed by machinists and toolroom technicians during routine insert changes or toolholder refurbishment.\u003c\/p\u003e\n\u003cp\u003eThis shim is intended for use in turning applications on CNC lathes and manual turning centers. It fits MVVNN and MVJNL\/MVJNR style toolholders in both modular and straight-shank configurations. Typical use is in production and job-shop turning environments where insert pocket longevity and consistent cutting geometry are required. The negative rake geometry suits applications where insert stability and edge strength take priority over cutting force reduction.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIVSN shim style with negative rake geometry for stable insert seating\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch inscribed circle (0.3750 inch decimal) fits standard diamond inserts\u003c\/li\u003e\n  \u003cli\u003eCompatible with MVVNN and MVJNL\/MVJNR series toolholder styles\u003c\/li\u003e\n  \u003cli\u003eProtects toolholder pocket from direct insert contact and wear\u003c\/li\u003e\n  \u003cli\u003eSold individually per package; minimum order quantity is 2 units\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eVerified compatible toolholders include: C4 MVJNL-27050-16, IM50 MVJNL-16, IM50 MVJNR-16, IM50 MVVNN-16, IM63 MVJNL-16, IM63 MVJNR-16, IM63 MVVNN-16, MVJNL 12-3, MVJNR 12-3, and MVJNR 16-3.

Before servicing, ensure the machine spindle is fully stopped, locked out, and the turret is in a safe position per shop lockout\/tagout procedures. Use the appropriate torx or hex key specified by the toolholder manufacturer for the clamping screw. Inspect the pocket and shim seating surface for chips or debris before reinstalling to maintain cutting geometry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShim Style\u003c\/strong\u003e: IVSN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndexable Tool Type\u003c\/strong\u003e: Turning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Shape\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style Compatibility\u003c\/strong\u003e: MVVNN, MVJNL, MVJNR\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: 0.5 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: 5505448\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51747377185074,"sku":"5505448","price":21.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/48f9e15c197435bdd9467e859edb0c39.jpg?v=1788879180","url":"https:\/\/voomisupply.com\/products\/iscar-5505448-indexable-shim-3-8-inch-ivsn-turning","provider":"Voomi Supply","version":"1.0","type":"link"}
