{"product_id":"seco-75069986-er25-collet-nut","title":"Seco 75069986 ER25 Collet Nut","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\n\u003cp\u003eThe SECO 75069986 is an ER25 collet nut designed for use with ER25 collet chucks in CNC machining and manual milling applications. The collet nut threads onto the collet chuck body and applies clamping force to seat the collet securely, maintaining tool concentricity during cutting operations. At 1 pound, it is a direct replacement component suited for shops and tool crib managers sourcing individual nuts rather than full chuck assemblies. Installation requires a standard ER25 spanner wrench and proper torque technique to avoid thread damage or collet distortion.\u003c\/p\u003e\n\u003cp\u003eThis collet nut is used wherever an ER25 toolholding system is in service, including CNC machining centers, manual mills, lathes with live tooling, and bench-top drilling setups. It is a common replacement item when threads show wear, when a nut is lost, or when a spare is needed to reduce downtime during tool changes. No coolant-through capability is present on this nut, making it appropriate for standard dry or flood-coolant setups where internal coolant delivery through the nut is not required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER25 collet series compatibility for broad toolholder fitment\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design suits standard flood and dry machining environments\u003c\/li\u003e\n  \u003cli\u003eSold individually, allowing single-unit replacement without purchasing a full assembly\u003c\/li\u003e\n  \u003cli\u003eLightweight at 1 pound for easy handling and tool crib stocking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement collet nut for ER25 series collet chuck systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Always power down and lock out the machine spindle before removing or installing a collet nut. Use a proper ER25 spanner wrench rather than improvised tools to avoid rounding the nut flats or cross-threading. Inspect collet and chuck threads for wear or contamination before installing the replacement nut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Collet Nut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 75069986\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558593528114,"sku":"75069986","price":92.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/69c0e693fb49d486e538ad789a192ed3.jpg?v=1786415212","url":"https:\/\/voomisupply.com\/products\/seco-75069986-er25-collet-nut","provider":"Voomi Supply","version":"1.0","type":"link"}
