The collet grips cutting tools, drill bits, and round-shank workholding accessories by compressing uniformly around the tool shank when a locking nut is tightened. The ER40 designation identifies the collet series and dictates compatibility with ER40-standard collet chucks and tool holders. Rated to 1000 units of clamping pressure, this collet delivers consistent, repeatable tool runout control critical to accurate machining operations. Machinists and CNC setup technicians handle installation as part of routine tool change procedures.\u003c\/p\u003e\n\u003cp\u003eThis collet is suited for production and job-shop environments where the ER40 system is the standard toolholding platform. Typical applications include end milling, drilling, reaming, and tapping on vertical or horizontal machining centers. The 16 mm bore accommodates tool shanks at that diameter, making it a common size for metric tooling programs. It is appropriate for both light-duty finishing cuts and moderate material-removal operations within the capacity of the ER40 system.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER40 series collet — fits all ER40-compatible chucks and tool holders\u003c\/li\u003e\n  \u003cli\u003e16 mm bore size for metric tool shanks\u003c\/li\u003e\n  \u003cli\u003e1000 rated clamping pressure for secure tool grip\u003c\/li\u003e\n  \u003cli\u003eUniform radial compression reduces tool runout\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package quantity for individual tooling builds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ER40-standard collet chucks and tool holders accepting a 16 mm collet bore.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians during tool change or setup procedures. Always power down and lock out the machine spindle before inserting or removing collets. Seat the collet fully into the collet chuck before engaging the locking nut, and inspect the collet bore and chuck taper for chips or debris prior to assembly. Do not exceed the manufacturer-recommended torque range for the locking nut as specified in the chuck documentation.\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\u003eCollet Bore Size\u003c\/strong\u003e: 16 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClamping Pressure Rating\u003c\/strong\u003e: 1000\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: 588516\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730019516722,"sku":"588516","price":62.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b35e5241e78b46ba73ab008a34302233.jpg?v=1788710300","url":"https:\/\/voomisupply.com\/products\/accupro-588516-er40-collet-16-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
