It accepts workpieces and cutting tools with a maximum capacity of 0.185 inches and a minimum collet capacity of 0.172 inches, providing a precise clamping range suitable for standard tooling in that diameter window. The collet operates under a rated pressure of 300 units and weighs 0.85 pounds. Machinists and tooling specialists install this collet as part of an ER40 collet chuck assembly to secure end mills, drill bits, reamers, and similar tooling during cutting operations.\u003c\/p\u003e\n\u003cp\u003eThe ACCUPRO 588240 ER40 collet is suited for use in machine shops running CNC mills, drill presses, lathes with live tooling, and similar equipment that accepts ER40-standard collet chucks. Its 0.185-inch capacity makes it a practical choice for shops needing a dedicated collet for tooling in that specific diameter range. Both production environments and job shops use ER-series collets as a reliable, interchangeable toolholding solution across a wide range of cutting operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER40 collet series — compatible with ER40-standard collet chucks\u003c\/li\u003e\n  \u003cli\u003e0.185-inch maximum collet capacity for precise toolholding in that diameter range\u003c\/li\u003e\n  \u003cli\u003eMinimum collet capacity of 0.172 inches provides a defined clamping window\u003c\/li\u003e\n  \u003cli\u003eRated pressure of 300 for consistent clamping force during operation\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package quantity allows purchase of individual collets to fill out a set\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or add-on collet for use in ER40-standard collet chuck systems.

Before inserting or removing the collet, the spindle must be fully stopped and the machine must be powered down or placed in a safe lockout state per facility safety procedures. The collet should be seated cleanly into the collet chuck nut and tightened with the appropriate ER40 spanner wrench to manufacturer-specified torque — do not use pipe wrenches or improvised tools. Inspect the collet bore and seating surface for chips or wear before each use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 0.185 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 0.172 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRated Pressure\u003c\/strong\u003e: 300\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.85 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 588240\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728291922226,"sku":"588240","price":34.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0093cced64ec96635a53ae836c561f63.jpg?v=1788690288","url":"https:\/\/voomisupply.com\/products\/accupro-588240-er40-collet-0-185-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
