It accepts shank tooling up to 0.375 inches (3\/8 inch) in diameter, with a minimum collet capacity of 0.343 inches, providing a secure clamping range suitable for end mills, drills, reamers, and similar cutting tools. Machinists and tool-crib technicians install ER collets as standard workholding components. The compact form factor measures 1.9 inches in height and 1.2 inches in width and length, and the unit weighs 0.05 pounds.\u003c\/p\u003e\u003cp\u003eThis collet is suited for light to medium-duty material removal operations in residential shop, commercial machine shop, and production environments. The ER20 series is a widely adopted collet standard, making this part a routine replacement or additional-inventory item for shops running ER20 toolholders. It is appropriate wherever precise, repeatable tool runout and consistent clamping force are required in an ER20 spindle setup.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER20 collet series for use with ER20-compatible toolholders\u003c\/li\u003e\n\u003cli\u003e0.375 inch (3\/8 inch) nominal collet size\u003c\/li\u003e\n\u003cli\u003eMinimum collet capacity of 0.343 inches for clamping range flexibility\u003c\/li\u003e\n\u003cli\u003eCompact dimensions: 1.9 inches height, 1.2 inches width, 1.2 inches length\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.05 pounds for easy handling during tool changes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard ER20-series collet for use in any ER20-compatible toolholder or collet chuck accepting 0.375 inch shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eER collets are installed by machinists and CNC operators. Before changing tooling, power down the spindle and verify the machine is in a safe, locked-out state per your facility lockout\/tagout procedures. Clean the toolholder bore and collet seating surface before installation to ensure proper runout. Do not exceed the collet clamping range; using tooling outside the specified capacity range can result in slippage or damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Size (Decimal Inch)\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Size (Fractional Inch)\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 0.343 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 784914\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732527644978,"sku":"784914","price":32.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/be0aab77a1a7eb2df76d885ac1671f47.jpg?v=1788744051","url":"https:\/\/voomisupply.com\/products\/accupro-784914-er20-collet-0-375-inch-3-8","provider":"Voomi Supply","version":"1.0","type":"link"}
