ER collets are precision workholding devices used in CNC machining centers, manual milling machines, and lathes to secure round cutting tools and workpieces within a collet chuck. The tight 0.0005-inch TIR rating ensures minimal tool runout, which directly supports accurate cuts, extended tool life, and consistent surface finishes. This collet weighs 0.5 pounds and is a single-piece unit packaged individually. It is installed and serviced by machinists and toolroom technicians.\u003c\/p\u003e\n\u003cp\u003eThis ER40 collet is suited for use in any machine tool equipped with an ER40-compatible collet chuck. The ER40 system is widely used in production and job-shop environments for milling, drilling, reaming, and tapping operations. The 0.5-inch bore accepts standard 1\/2-inch shank cutting tools including end mills, drill bits, and reamers. It is appropriate for both light-duty finishing passes and heavier material removal operations within the torque limits of the host collet chuck.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER40 collet series for use with ER40-compatible collet chucks\u003c\/li\u003e\n  \u003cli\u003e0.5-inch (1\/2-inch) bore diameter accepts standard 1\/2-inch shank tooling\u003c\/li\u003e\n  \u003cli\u003e0.0005-inch TIR for precise tool concentricity and reduced runout\u003c\/li\u003e\n  \u003cli\u003eSingle-piece unit sold individually (package quantity of 1)\u003c\/li\u003e\n  \u003cli\u003eWeighs 0.5 pounds for easy handling and tool change efficiency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with any machine tool spindle or toolholder equipped with an ER40-compatible collet chuck.

Before installing or removing the collet, power down the machine and ensure the spindle has come to a complete stop. Insert the collet into the ER40 collet nut before threading the nut onto the chuck body, then tighten to the chuck manufacturer's specified torque using an appropriate collet wrench. Inspect the collet bore and seating surfaces for chips or contamination prior to each use, as debris will degrade TIR performance.\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 Size (Decimal Inch)\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Size (Fractional Inch)\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 204-4032\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701586854194,"sku":"204-4032","price":27.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c309dd3687ef8690f048a88ad9ba2b36.jpg?v=1788402055","url":"https:\/\/voomisupply.com\/products\/value-collection-204-4032-er40-collet-0-5-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
