It seats beneath a replaceable insert to establish correct cutting height and maintain consistent tool geometry at the holder. The IRSN-32 carries a negative rake orientation and is built to the IRSN industry standard. With a 3\/8 inch inscribed circle and a thickness of 1\/8 inch (0.1250 inches), this shim provides precise, repeatable positioning for cylindrical insert shapes in turning and boring operations. Machinists and toolroom technicians working with indexable toolholders rely on correctly specified shims to protect the holder pocket and extend insert life.\u003c\/p\u003e\n\u003cp\u003eThis shim is used in metalworking and machining environments where indexable insert toolholders require a hardened seating surface under the insert. Typical applications include CNC turning centers, manual lathes, and boring bars equipped with negative-rake indexable insert pockets. The IRSN series designation ties directly to the industry standard number IRSN-32, making cross-referencing against existing toolholder documentation straightforward for shop personnel sourcing replacement hardware.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction resists deformation under high cutting loads\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch (0.3750 inches) inscribed circle matches cylindrical insert footprint\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch (0.1250 inches) thickness for precise insert height setting\u003c\/li\u003e\n  \u003cli\u003eNegative rake geometry compatible with IRSN-series toolholders\u003c\/li\u003e\n  \u003cli\u003eConforms to IRSN industry standard number IRSN-32 for direct cross-reference\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement shim for IRSN-series indexable toolholders accepting cylindrical inserts with a 3\/8 inch inscribed circle and negative rake seating geometry.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians during insert changes or holder reconditioning. Secure all machine axes and confirm the spindle is fully stopped before accessing the toolholder pocket. Inspect the holder pocket seat for wear or debris before placing the shim. Follow the toolholder manufacturer torque and clamping sequence for the insert screw to avoid shim fracture or pocket damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShim Style\u003c\/strong\u003e: IRSN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: IRSN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: IRSN-32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Shape\u003c\/strong\u003e: Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed 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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: IRSN-32\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":68387370107186,"sku":"IRSN-32","price":353.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/982029ae647f8526cb0727aa1f945f2f.jpg?v=1793903850","url":"https:\/\/voomisupply.com\/products\/value-collection-irsn-32-indexable-shim-3-8-in-negative-rake","provider":"Voomi Supply","version":"1.0","type":"link"}
