With a collet size of 13mm and a total indicator runout (TIR) of 0.0002 inches (0.005mm), this collet delivers the accuracy required for tight-tolerance toolholding. The through-coolant feature allows cutting fluid to flow directly to the cutting zone, supporting longer tool life and better chip evacuation. Machinists and CNC operators working with ER20-compatible toolholding systems will find this collet a direct fit for standard ER20 chucks and collet holders.\u003c\/p\u003e\n\u003cp\u003eThis collet is suited for use in vertical and horizontal machining centers, CNC mills, and multi-axis machines that accept ER20 collet chucks. It handles shank tooling at the 13mm size, making it appropriate for end mills, drills, reamers, and taps within that diameter range. The through-coolant design makes it particularly useful in high-speed or deep-pocket machining where flood coolant alone may not reach the cutting edge effectively.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER20 collet series for compatibility with standard ER20 chucks and holders\u003c\/li\u003e\n  \u003cli\u003e13mm collet size for direct toolholder fitment at that shank diameter\u003c\/li\u003e\n  \u003cli\u003eTIR of 0.0002 inches (0.005mm) for precision toolholding with minimal runout\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design channels cutting fluid directly to the tool tip\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.5 pounds for easy handling and quick changeout\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard fitment collet for ER20-compatible collet chucks and toolholding systems accepting 13mm shank tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC toolroom technicians. Always power down and lock out the machine spindle before changing collets. Ensure the collet, chuck bore, and clamping nut are clean and free of chips or debris before seating the collet. Do not exceed the torque or clamping specifications listed by the chuck manufacturer for ER20 components.\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: 13mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0002 inches (0.005mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\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  \u003cli\u003e\n\u003cstrong\u003eProduct Service Code\u003c\/strong\u003e: 5136\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: 04220-13\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TECHNIKS","offers":[{"title":"Default Title","offer_id":52107320131890,"sku":"04220-13","price":49.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/93edbe269629ddb0f00bb14261185a0a_99d511d9-9334-4992-8aa0-2fa0d7bb3237.jpg?v=1790074143","url":"https:\/\/voomisupply.com\/products\/techniks-04220-13-er20-collet-13mm-through-coolant","provider":"Voomi Supply","version":"1.0","type":"link"}
