Shims seat beneath the cutting insert to provide a stable, repeatable seating surface and protect the toolholder pocket from wear. This shim carries a negative rake geometry and is sized for a 0.5-inch inscribed circle, making it compatible with diamond-shaped inserts in that size class. Thickness is 0.25 inches. At 0.003 pounds, it is a lightweight precision component intended for OEM-matched installation in compatible turning tool assemblies. Machinists and toolroom technicians working with Walter-compatible boring bars and turning holders will recognize this as a standard AP-series replacement shim.\u003c\/p\u003e\u003cp\u003eThis shim is used in CNC and manual turning applications where indexable insert toolholders require a seating shim beneath the cutting insert. The AP shim style and negative rake orientation are common in external and internal turning setups. Compatible toolholders include both straight-shank and cylindrical-shank styles in multiple sizes, covering a range of boring bar and turning holder configurations. This part is suited for production turning environments where toolholder pocket integrity and consistent insert indexing are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAP shim style for compatibility with AP-series indexable turning toolholders\u003c\/li\u003e\n\u003cli\u003eNegative rake geometry matches standard negative-insert seating requirements\u003c\/li\u003e\n\u003cli\u003e0.5-inch inscribed circle fits diamond-shaped inserts in that size class\u003c\/li\u003e\n\u003cli\u003eThickness of 0.25 inches provides consistent insert height positioning\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.003 pounds for minimal toolholder mass impact\u003c\/li\u003e\n\u003cli\u003eCompatible with a wide range of Walter A-series and C-series turning holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible toolholders as specified by the manufacturer: A16T-DDUNR\/L4, A20T-DDUNR\/L4, A24T-DDUNR\/L4, A32T-DDUNR\/L15, A32U-DDUNR\/L 4, A40T-DDUNR\/L15, A50U-DDUNR\/L15, C4-DDJNR\/L-27055-15, C4-DDUNR\/L-27050-15, C4-DDUNR\/L-27080-15, C5-DDJNR\/L-35060-15, C5-DDMNL-00115-15, C5-DDUNR\/L-27140-15, C5-DDUNR\/L-35060-15.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a qualified machinist or toolroom technician during insert indexing or toolholder maintenance. Power down and de-energize the machine before servicing the toolholder. Ensure the shim seat and toolholder pocket are clean and free of chips or debris before placing the shim. Follow the toolholder manufacturer torque specifications for the insert clamping screw  -  do not overtighten, as this can deform the shim or damage the pocket.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: AP\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\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.003 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WALTER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5102612\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":52063264670002,"sku":"5102612","price":310.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6bd9eababc2c08dc9b6473b204cf8710_bf03aa0f-2a5d-49cc-875d-8cb9b674bb64.jpg?v=1790043192","url":"https:\/\/voomisupply.com\/products\/walter-5102612-ap-shim-negative-rake-0-5-inch-turning","provider":"Voomi Supply","version":"1.0","type":"link"}
