It holds workpieces or cutting tools to a clamping diameter of 10.50mm and delivers a Total Indicator Runout (TIR) of 0.0002 inches (0.0050mm), making it suitable for close-tolerance work where concentricity matters. The collet includes through-coolant capability, allowing coolant to flow directly to the cutting zone. Machinists, toolroom technicians, and CNC setup personnel install this collet into compatible ER20 collet chucks as part of standard toolholding setups on mills, lathes, and machining centers.\u003c\/p\u003e\n\u003cp\u003eThe 04220-10.5 fits into any ER20-standard collet chuck. It is appropriate for residential shop, commercial job shop, and production machining environments. Through-coolant support makes it well suited for deep-hole drilling, high-speed milling, and other operations where direct coolant delivery improves tool life and chip evacuation. No specific machine brand is required beyond ER20 chuck compatibility.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER20 collet series  -  fits any ER20-standard chuck body\u003c\/li\u003e\n  \u003cli\u003e10.50mm clamping diameter for precise tool or workpiece holding\u003c\/li\u003e\n  \u003cli\u003eTIR of 0.0002 inches (0.0050mm) for close-tolerance concentricity\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design directs coolant to the cutting zone\u003c\/li\u003e\n  \u003cli\u003eCompact form factor at 0.5 pounds for easy handling and quick changeover\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard toolholding collet for use with ER20-standard collet chucks across mills, lathes, and machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or toolroom technician. Power down and lock out the spindle before installing or removing the collet. Seat the collet fully into the ER20 collet nut before threading onto the chuck body, and torque the nut using the appropriate ER collet wrench to manufacturer specifications. Inspect the collet bore and mating surfaces for chips or debris before each use to maintain 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: ER20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Size\u003c\/strong\u003e: 10.50mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0002 inches (0.0050mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\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: TECHNIKS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 04220-10.5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TECHNIKS","offers":[{"title":"Default Title","offer_id":51972178837810,"sku":"04220-10.5","price":49.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/93edbe269629ddb0f00bb14261185a0a_593a19d1-945a-4685-98d9-ce587fbbf5b3.jpg?v=1789963788","url":"https:\/\/voomisupply.com\/products\/techniks-04220-10-5-er20-collet-10-50mm","provider":"Voomi Supply","version":"1.0","type":"link"}
