The shim seats beneath a diamond-shaped indexable insert and maintains proper insert height and seating geometry throughout the cutting cycle. At 0.125 inches thick and sized for a 3\/8-inch inscribed circle insert, it is a precision-ground component that directly affects tool performance and surface finish quality. Negative rake geometry is built into the shim design to match compatible negative-rake insert configurations. This part is sold individually and is intended for replacement in existing toolholder assemblies by machining professionals and toolroom technicians.\u003c\/p\u003e\n\u003cp\u003eThis shim is used in boring bar applications where indexable diamond-shaped inserts require a supporting shim beneath the insert pocket. Typical installation scenarios include replacement after insert wear or damage to the seating surface, toolholder refurbishment, and assembly of new boring bar bodies. It is suited for both manual and CNC turning and boring operations in production and job-shop environments where consistent insert positioning is required for dimensional accuracy.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIVSN shim style for compatibility with negative-rake indexable boring bar toolholders\u003c\/li\u003e\n  \u003cli\u003eFits diamond-shaped inserts with a 3\/8-inch (0.3750 inch) inscribed circle\u003c\/li\u003e\n  \u003cli\u003eThickness of 1\/8 inch (0.1250 inch) for precise insert height control\u003c\/li\u003e\n  \u003cli\u003eNegative rake design matches corresponding insert and toolholder geometry\u003c\/li\u003e\n  \u003cli\u003eSold as a single piece; minimum order quantity of 10 units applies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with boring bar toolholders that accept diamond-shaped indexable inserts with a 3\/8-inch inscribed circle and require an IVSN-style shim with negative rake geometry.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machining professionals or toolroom technicians during insert changes or toolholder maintenance. The machine spindle and all cutting motion must be fully stopped and the machine locked out before accessing the toolholder. The shim seat should be cleaned of chips and debris before the replacement shim is seated to ensure flat, even contact. Do not force the shim into position; proper seating is required to maintain insert geometry and prevent premature tool failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Shim for Indexables\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShim Style\u003c\/strong\u003e: IVSN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Shape\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\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\u003eIndexable Tool Type\u003c\/strong\u003e: Boring Bar\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1017226\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732990624050,"sku":"1017226","price":424.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4afdcc672c5bbf51668d4fd3518934b3.jpg?v=1788750122","url":"https:\/\/voomisupply.com\/products\/kennametal-1017226-indexable-shim-3-8-in-boring-bar-ivsn","provider":"Voomi Supply","version":"1.0","type":"link"}
