The collet has a decimal inch size of 0.153 inches and a minimum collet capacity of 0.141 inches, allowing it to clamp round shank cutting tools and workholding extensions within that clamping range. Overall length is 1.22 inches. Machinists and CNC operators install this collet when precise, repeatable tool clamping is required in an ER20-compatible chuck or toolholder.\u003c\/p\u003e\n\u003cp\u003eThis collet is suited for production and maintenance machining environments where ER20 tooling systems are standard. Typical applications include end mill clamping, drill holding, and reamer holding in light to medium-duty CNC or manual milling operations. The 0.153 inch size addresses tooling that falls within the ER20 clamping range and is packaged as a single unit for direct replacement or inventory replenishment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER20 collet series for use in ER20-compatible chucks and toolholders\u003c\/li\u003e\n  \u003cli\u003e0.153 inch nominal collet size with a minimum capacity of 0.141 inches\u003c\/li\u003e\n  \u003cli\u003eOverall length of 1.22 inches for standard ER20 spindle depth requirements\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.1 pounds for minimal spindle load contribution\u003c\/li\u003e\n  \u003cli\u003eSingle-unit packaging supports direct replacement without minimum quantity commitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement collet for use in any ER20-compatible collet chuck or toolholding system accepting the ER20 standard collet form factor.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC technicians. Before installing or removing a collet, the spindle must be fully stopped and the machine placed in an e-stop or powered-down state per the machine tool manufacturer guidelines. The collet should be seated fully in the nut before threading onto the chuck body. Do not exceed the torque range specified by the toolholder manufacturer for ER20 collet nuts.\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: 0.153 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.22 inches\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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 784804\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51734865019186,"sku":"784804","price":48.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/63c2049cefc70ee41fe420c1ffaab70d.jpg?v=1788767436","url":"https:\/\/voomisupply.com\/products\/accupro-784804-er20-collet-0-153-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
