It holds workpieces and cutting tools with a minimum collet capacity of 0.451 inches and delivers a total indicator runout (TIR) of 0.0002 inches, supporting tight-tolerance machining operations. The overall length is 1.811 inches. Machinists, tool-and-die professionals, and CNC operators rely on this collet for consistent, repeatable clamping across high-cycle production and precision job-shop work.\u003c\/p\u003e\u003cp\u003eThis collet is suited for use in vertical and horizontal machining centers, CNC mills, and drill presses equipped with ER40 collet chucks. The 0.5-inch nominal size accommodates standard half-inch shank cutting tools including end mills, drills, reamers, and taps. It is appropriate for both production and prototype environments where dimensional accuracy and tool concentricity are critical to part quality.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER40 series collet with 0.5 inch nominal bore size\u003c\/li\u003e\n\u003cli\u003eTIR of 0.0002 inches for precision tool holding\u003c\/li\u003e\n\u003cli\u003eMinimum collet capacity of 0.451 inches accommodates near-nominal shank diameters\u003c\/li\u003e\n\u003cli\u003eOverall length of 1.811 inches fits standard ER40 chuck pockets\u003c\/li\u003e\n\u003cli\u003eOverall diameter of 1.614 inches conforms to ER40 collet body geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with ER40-compatible collet chucks.

Power down and lock out the machine spindle before inserting or removing the collet. Seat the collet fully into the ER40 nut before threading the nut onto the chuck body, and torque the nut using an appropriate ER collet wrench to manufacturer-specified values for the chuck. Inspect the collet bore and seating surfaces for chips or debris before each use to maintain TIR performance.\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\u003eCollet Size\u003c\/strong\u003e: 0.5 inches (1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 0.451 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\u003eOverall Diameter\u003c\/strong\u003e: 1.614 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.56 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: 5UMER40-0500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARLEC","offers":[{"title":"Default Title","offer_id":52108641567026,"sku":"5UMER40-0500","price":92.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/82d17e09ea336083fc32caa9c478d878.jpg?v=1790075039","url":"https:\/\/voomisupply.com\/products\/parlec-5umer40-0500-er40-collet-0-5-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
