The collet nut threads onto the tool holder body and applies uniform clamping force to the collet, holding cutting tools firmly in place during milling, drilling, and engraving operations. Weighing 1 pound, this nut is built for repeated use in production environments. It is installed and removed by machinists and toolroom technicians using a standard ER11 spanner wrench. Proper torque and clean threads are essential for accurate tool runout and safe operation.\u003c\/p\u003e\n\u003cp\u003eThe ACCUPRO 776908 is suited for use with ER11 series collet chucks found on CNC machining centers, routers, and engraving machines. The ER11 collet system is widely used in high-speed spindle applications and benchtop CNC setups where smaller-diameter tooling is common. This nut is a direct replacement or spare component for existing ER11 tool holder assemblies in both production and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCompatible with ER11 series collet chucks and tool holders\u003c\/li\u003e\n  \u003cli\u003eApplies uniform clamping force for consistent tool retention\u003c\/li\u003e\n  \u003cli\u003eSold individually, allowing single-unit replacement\u003c\/li\u003e\n  \u003cli\u003eWeighs 1 pound for stable feel during installation and removal\u003c\/li\u003e\n  \u003cli\u003eDesigned for repeated installation and removal cycles in production use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement collet nut for ER11 series collet chuck tool holders used in CNC machining, routing, and engraving applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolroom technicians. Always power down and lock out the spindle before removing or installing a collet nut. Use a properly sized ER11 spanner wrench to achieve adequate clamping torque. Inspect the nut threads and mating tool holder threads for damage or contamination before each use to maintain tool runout accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Collet Nut\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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 776908\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731014287666,"sku":"776908","price":39.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/85c10ce446bc682e3f9e246644bd1380.jpg?v=1788725880","url":"https:\/\/voomisupply.com\/products\/accupro-776908-er11-collet-nut","provider":"Voomi Supply","version":"1.0","type":"link"}
