It accepts an 8 mm bore diameter and has an overall length of 1.24 inches, fitting within the compact ER20 collet standard. The collet exerts a clamping pressure of 1800 units to grip cutting tools, drill bits, and round-shank tooling securely during high-speed operation. Machinists and toolroom technicians install this collet as a standard component of ER-style toolholding systems where repeatable, concentric tool clamping is required.\u003c\/p\u003e\n\u003cp\u003eThis collet is suited for light to medium-duty machining applications in production and job-shop environments. The ER20 series is a widely adopted collet standard used in milling, drilling, tapping, and reaming operations. Its compact overall diameter of 0.827 inches makes it appropriate for toolholding chucks that require a low-profile, high-precision collet in confined spindle environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER20 collet series with 8 mm bore for standard round-shank tooling\u003c\/li\u003e\n  \u003cli\u003eOverall length of 1.24 inches for use in ER20-compatible chucks\u003c\/li\u003e\n  \u003cli\u003eOverall diameter of 0.827 inches matching ER20 collet geometry\u003c\/li\u003e\n  \u003cli\u003e1800 clamping pressure rating for secure tool retention during operation\u003c\/li\u003e\n  \u003cli\u003eDesigned for CNC milling, drilling, tapping, and reaming applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement collet for ER20-compatible toolholding chucks and collet nuts used in CNC machining centers and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Before changing collets, power down the spindle and confirm the machine is in a safe, locked-out state per shop safety procedures. Insert the collet into the ER20 chuck body and engage the collet nut hand-tight before torquing with the appropriate ER collet nut wrench. Do not use damaged or out-of-spec collets, as this can result in tool runout or tool ejection during operation.\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\u003eBore Size\u003c\/strong\u003e: 8 mm\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\u003eClamping Pressure\u003c\/strong\u003e: 1800\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: ERS20-0315\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARLEC","offers":[{"title":"Default Title","offer_id":51969344504114,"sku":"ERS20-0315","price":78.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/29f1601da1282763927328ebf1fa7acf.jpg?v=1789952206","url":"https:\/\/voomisupply.com\/products\/parlec-ers20-0315-er20-collet-8mm-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
