It seats beneath the cutting insert to maintain precise insert positioning and protect the toolholder pocket from wear and impact loading. This shim follows the CCMM12 shim style and is engineered for negative-rake insert configurations using diamond-shaped inserts with a 0.5 inch inscribed circle. At 0.1250 inches thick, it restores correct insert seating height after pocket wear or insert changes. Machinists and CNC turning specialists install this component during routine insert changes or toolholder refurbishment on turning centers and engine lathes.\u003c\/p\u003e\u003cp\u003eThis shim is suited for production turning applications where consistent insert height and repeatable tool offset values are critical. It is compatible with CCMM12-series toolholder pockets that accept diamond-shaped negative-rake inserts. Shops running high-volume turning operations benefit from keeping spare shims on hand to minimize toolholder downtime during insert indexing cycles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCCMM12 shim style for direct fitment in compatible CCMM12 toolholder pockets\u003c\/li\u003e\n\u003cli\u003eDesigned for diamond-shaped inserts with 0.5 inch inscribed circle\u003c\/li\u003e\n\u003cli\u003eNegative-rake geometry compatible with negative insert configurations\u003c\/li\u003e\n\u003cli\u003e0.1250 inch thickness maintains precise insert seating height\u003c\/li\u003e\n\u003cli\u003eProtects toolholder pocket from direct cutting load and insert-edge contact\u003c\/li\u003e\n\u003cli\u003eIndustry standard number 16085 for cross-reference sourcing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CCMM12-series indexable turning toolholder pockets accepting diamond-shaped negative-rake inserts with a 0.5 inch inscribed circle.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians during insert changes or toolholder servicing. Ensure the machine spindle is powered down and all motion has stopped before accessing the toolholder pocket. Seat the shim flat in the pocket before placing the insert, and confirm the clamp screw torque follows the toolholder manufacturer specifications. Inspect the pocket and shim seating surface for chips or debris before assembly to maintain insert stability and dimensional repeatability.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShim Style\u003c\/strong\u003e: CCMM12\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 (11.10 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle Decimal\u003c\/strong\u003e: 0.4375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1250 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: 16085\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 74016085\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51561067479346,"sku":"74016085","price":34.5,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bd96495143f02ad468b08626eb1b01a3.jpg?v=1786462300","url":"https:\/\/voomisupply.com\/products\/seco-74016085-indexable-turning-shim-ccmm12-diamond-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
