It holds tooling at a decimal inch size of 0.313 inches, with a minimum collet capacity of 0.281 inches, making it suitable for clamping end mills, drills, reamers, and other round-shank cutting tools within that clamping range. The collet measures 1.75 inches in width, 1.75 inches in length, and 2 inches in height, and weighs 0.6 pounds. It is sold individually and is intended for use by machinists, toolroom technicians, and CNC setup personnel.\u003c\/p\u003e\n\u003cp\u003eThis collet is suited for production and job-shop machining environments where the ER40 standard is already in use. The ER40 collet series is one of the most widely adopted collet systems in general-purpose machining, found in both horizontal and vertical machining centers, manual mills, and dedicated collet chucks. This unit is appropriate for facilities running precision turning, milling, drilling, or tapping operations that require consistent tool runout and secure shank retention in the 0.281 to 0.313 inch clamping range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER40 collet series for use with compatible ER40 tool holders and collet chucks\u003c\/li\u003e\n  \u003cli\u003eDecimal inch collet size of 0.313 inches\u003c\/li\u003e\n  \u003cli\u003eMinimum collet capacity of 0.281 inches for clamping range flexibility\u003c\/li\u003e\n  \u003cli\u003eCompact form factor: 1.75 inches wide, 1.75 inches long, 2 inches tall\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.6 pounds for easy single-handed handling during tool changes\u003c\/li\u003e\n  \u003cli\u003eSold individually, allowing targeted replacement or inventory expansion\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ER40 collet for use with any tool holder, collet chuck, or spindle nut assembly manufactured to the ER40 collet specification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom personnel. Before inserting or removing a collet, ensure the machine spindle is fully stopped and locked out per applicable lockout\/tagout procedures. Seat the collet into the collet nut before threading onto the tool holder to prevent damage to the collet taper. Do not overtighten the collet nut beyond the tool holder manufacturer's specified torque range, and inspect the collet bore and taper for wear or contamination before each use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Size (Decimal Inch)\u003c\/strong\u003e: 0.313 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 0.281 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.6 pounds\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: 785064\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51733183201586,"sku":"785064","price":44.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9cf0895db2301974159dcf2cdf35a1c6.jpg?v=1788752469","url":"https:\/\/voomisupply.com\/products\/accupro-785064-er40-collet-0-313-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
