It accepts ER20 collets with a capacity range from 1\/16 inch minimum to 0.512 inches maximum, covering a broad range of tooling diameters. The chuck features a 10-inch projection and an overall length of 12.687 inches, making it suited for deep-reach setups where standard-projection toolholders cannot access the workpiece. Installation and removal are handled by licensed machine tool technicians or skilled CNC operators.\u003c\/p\u003e\n\u003cp\u003eThis collet chuck is used in vertical and horizontal machining centers equipped with CAT40 spindle interfaces. The extended 10-inch projection is particularly useful in mold and die work, deep-cavity milling, and other applications where clearance between the spindle nose and the workpiece is required. The ER20 collet system is a widely adopted standard, and collets across this series are sourced from multiple tooling suppliers. The 22239-10 ships as a single unit and is stocked as a direct replacement or new-setup toolholder.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER20 collet system with capacity from 1\/16 inch to 0.512 inches maximum\u003c\/li\u003e\n  \u003cli\u003eCAT40 taper shank for compatibility with standard CAT40 spindle interfaces\u003c\/li\u003e\n  \u003cli\u003e10-inch projection for extended reach in deep-cavity machining applications\u003c\/li\u003e\n  \u003cli\u003eOverall length of 12.687 inches\u003c\/li\u003e\n  \u003cli\u003eNut tightening torque specification of 59 ft-lb for proper collet seating\u003c\/li\u003e\n  \u003cli\u003eWeighs 5 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers with CAT40 spindle interfaces using the ER20 collet system.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified CNC machine tool technicians following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing toolholders. Use a proper ER20 collet chuck wrench and spanner to achieve the specified nut tightening torque. Inspect the taper shank and spindle bore for debris or damage before seating the chuck.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet System\u003c\/strong\u003e: ER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTaper Size\u003c\/strong\u003e: CAT40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 1\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Collet Capacity\u003c\/strong\u003e: 0.512 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12.687 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNut Tightening Torque\u003c\/strong\u003e: 59 ft-lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112808\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: TECHNIKS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 22239-10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TECHNIKS","offers":[{"title":"Default Title","offer_id":67581971628338,"sku":"22239-10","price":307.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/31e74ab0f0814455e56b25e2455c923d_c13b4a23-a096-41ab-b890-466ceb59defa.jpg?v=1790410586","url":"https:\/\/voomisupply.com\/products\/techniks-22239-10-er20-collet-chuck-cat40-taper-10-in","provider":"Voomi Supply","version":"1.0","type":"link"}
