It accepts a nominal 0.5 inch (1\/2 inch) shank diameter with a minimum collet capacity of 0.461 inches, providing a controlled clamping range suited to close-tolerance work. The collet measures 1.24 inches in overall length and 0.827 inches in overall diameter. Machinists and tool crib personnel working with ER20-compatible toolholders will find this collet a direct-fit solution for standard round-shank tooling and workholding applications.\u003c\/p\u003e\n\u003cp\u003eThis collet is intended for use in ER20-standard collet chucks found in light-duty to medium-duty machining environments. Typical applications include end mill holding, drill chuck replacement setups, tapping attachments, and CNC turning or milling operations where an ER20 system is already in place. The compact overall length suits toolholders with limited gage-length clearance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER20 collet series for use with ER20-compatible toolholders and collet chucks\u003c\/li\u003e\n  \u003cli\u003e0.5 inch nominal collet size with a minimum capacity of 0.461 inches\u003c\/li\u003e\n  \u003cli\u003e1.24 inch overall length for compact toolholder fitment\u003c\/li\u003e\n  \u003cli\u003e0.827 inch overall diameter consistent with ER20 series standards\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.1 pounds for easy handling and low spindle mass contribution\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or supplemental collet for ER20-standard collet chuck systems used in CNC milling, drilling, and tapping applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or tool crib technician. Ensure the spindle or toolholder is fully de-energized and at rest before changing collets. Seat the collet fully into the nut before threading onto the chuck body to prevent damage to the collet taper. Torque the collet nut using the appropriate ER20 spanner wrench; do not use improvised tools that may distort the nut or collet flange.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Size (Fraction)\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 0.461 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.24 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 0.827 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Service Code\u003c\/strong\u003e: 5136\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: PARLEC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ER20-0500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARLEC","offers":[{"title":"Default Title","offer_id":52083337658674,"sku":"ER20-0500","price":41.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d3cf45959250c690a1661638b540d2e7.jpg?v=1790057456","url":"https:\/\/voomisupply.com\/products\/parlec-er20-0500-er20-collet-1-2-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
