It accepts workpieces and cutting tools up to 0.218 inches in diameter, with a minimum collet capacity of 0.179 inches, giving it a clamping range suited to standard end mills, drills, and reamers in that size window. The overall length is 1.811 inches. Machinists and toolroom technicians install this collet into an ER40-compatible collet chuck or tool holder to achieve accurate, repeatable tool runout during cutting operations.\u003c\/p\u003e\u003cp\u003eThis collet is appropriate for job shops, production machining environments, and maintenance toolrooms running ER40 tooling systems. It fits standard ER40 collet chucks used on vertical and horizontal machining centers, CNC lathes with live tooling, and manual mills equipped with ER40 holders. The 0.218-inch bore size is well suited for holding fractional and wire-gauge cutting tools commonly used in general-purpose metal removal and light finishing work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER40 series collet with 0.218 inch maximum clamping capacity\u003c\/li\u003e\n\u003cli\u003eMinimum collet capacity of 0.179 inches provides a defined clamping range\u003c\/li\u003e\n\u003cli\u003eOverall length of 1.811 inches for compatibility with standard ER40 chuck depths\u003c\/li\u003e\n\u003cli\u003eDesigned for accurate tool holding with repeatable runout performance\u003c\/li\u003e\n\u003cli\u003eSingle-piece unit sold individually, no additional components required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit collet for ER40-compatible collet chucks and tool holders used in standard CNC and manual machining applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Before installing or changing collets, the machine spindle must be fully stopped and locked out per shop lockout\/tagout procedures. Seat the collet into the collet nut before threading onto the chuck body, and use a calibrated torque wrench appropriate for ER40 collet nuts to achieve proper clamping force without damaging the collet taper. Inspect the collet bore and chuck taper for chips or contamination before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Collet Capacity\u003c\/strong\u003e: 0.218 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 0.179 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.811 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: PARLEC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ER40-0218\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARLEC","offers":[{"title":"Default Title","offer_id":67913018868018,"sku":"ER40-0218","price":55.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cb9ac92b366e6dcbaf6c4351dd4c19f3_9d30421e-7f67-46da-b81e-f155d75ba971.jpg?v=1791241616","url":"https:\/\/voomisupply.com\/products\/parlec-er40-0218-er40-collet-0-218-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
