The collet holds workpieces or cutting tools with a clamping diameter of 0.75 inches and delivers a total indicator runout (TIR) of 0.0005 inches, making it suitable for precision machining operations where concentricity is critical. Machinists and tool-room technicians install these collets when setting up end mills, drills, reamers, or round-shank tooling in ER40-compatible toolholders.\u003c\/p\u003e\n\u003cp\u003eThis collet is intended for use in ER40 collet chucks found on vertical and horizontal machining centers, manual milling machines, and lathe live-center applications in both production and job-shop environments. The 0.75-inch bore size accommodates standard round-shank tooling and workpieces of that diameter. It is a single-piece collet sold individually and suits shops that need a replacement or additional collet for an existing ER40 chuck setup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER40 collet series — fits all ER40-compatible collet chucks\u003c\/li\u003e\n  \u003cli\u003e0.75-inch clamping diameter for standard round-shank tooling\u003c\/li\u003e\n  \u003cli\u003e0.0005-inch TIR for precision concentricity in critical machining operations\u003c\/li\u003e\n  \u003cli\u003eSold individually, allowing targeted replacement without buying a full set\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.44 pounds for easy handling during tool changes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or supplemental collet for use in any ER40-standard collet chuck accepting a 0.75-inch bore collet.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or tool-room technicians following standard toolholding procedures. Before inserting or removing a collet, ensure the machine spindle is fully stopped and the tool changer or spindle lock is engaged per the machine manufacturer's guidelines. Seat the collet fully into the ER40 collet nut before threading the nut onto the chuck body, and torque the nut with the appropriate ER40 spanner wrench to the chuck manufacturer's specification. Inspect the collet bore and seating taper for chips or debris before each use to maintain the rated TIR.\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: 0.7500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Size (Fractional)\u003c\/strong\u003e: 3\/4 inches\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: 0.44 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: 204-4048\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51702366863666,"sku":"204-4048","price":27.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/24a61cb4ca23537e733ab6059e96c742.jpg?v=1788410475","url":"https:\/\/voomisupply.com\/products\/value-collection-204-4048-er40-collet-0-75-in","provider":"Voomi Supply","version":"1.0","type":"link"}
