With a collet size of 0.187 inches and a minimum collet capacity of 0.148 inches, this collet clamps tool shanks securely within its clamping range. The overall length is 0.708 inches and the overall diameter is 0.452 inches. Machinists and tool room technicians install this collet into compatible ER11 collet chucks to hold end mills, drills, reamers, and other round-shank tooling during cutting operations. Its compact ER11 form factor suits smaller spindle applications where controlled runout and consistent clamping force are required.\u003c\/p\u003e\u003cp\u003eThis collet is used in ER11 collet chucks found on CNC machining centers, milling machines, lathes with live tooling, and high-speed spindle units. It is suited for light-duty precision machining in both production and tool room environments. The 0.187-inch nominal capacity accommodates standard fractional shank tooling at that diameter. Typical applications include drilling, reaming, and light milling where a compact collet chuck system is specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER11 collet series for use in ER11-compatible collet chucks\u003c\/li\u003e\n\u003cli\u003e0.187-inch collet size with a minimum collet capacity of 0.148 inches\u003c\/li\u003e\n\u003cli\u003eOverall length of 0.708 inches for compact spindle installations\u003c\/li\u003e\n\u003cli\u003eOverall diameter of 0.452 inches\u003c\/li\u003e\n\u003cli\u003eLightweight construction at 0.03 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit collet for ER11 series collet chucks and compatible toolholding systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eER11 collets are installed and removed by a machinist or tool room technician using the appropriate ER11 collet nut and spanner wrench. Always ensure the spindle or collet chuck is fully powered down and at rest before changing collets. Inspect the collet bore and chuck taper for debris or damage before seating the collet. Do not exceed the collet clamping range when inserting tool shanks.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Size\u003c\/strong\u003e: 0.187 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 0.148 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.708 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 0.452 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: ER11-0187\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARLEC","offers":[{"title":"Default Title","offer_id":51985490903346,"sku":"ER11-0187","price":42.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e83fe12327df14047a050964eacbaa22.jpg?v=1789985515","url":"https:\/\/voomisupply.com\/products\/parlec-er11-0187-er11-collet-0-187-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
