With a 5.5mm collet size and a total indicator runout (TIR) of 0.005mm, this collet delivers the accuracy required for close-tolerance milling, drilling, and reaming operations. Through-coolant capability allows cutting fluid to be delivered directly to the cutting zone, extending tool life and improving chip evacuation. Machinists and toolroom technicians install this collet into compatible ER16 collet chucks as part of standard CNC or manual machine setups.\u003c\/p\u003e\u003cp\u003eThe TECHNIKS 04216-05.5 is suited for use in machine shops, production facilities, and toolroom environments where ER16 collet systems are in service. It fits ER16-spec collet chucks used on CNC machining centers, CNC lathes with live tooling, and manual milling machines. The through-coolant feature makes it a practical choice for deep-hole drilling and high-speed operations where heat management is a priority.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER16 collet series for broad chuck compatibility\u003c\/li\u003e\n\u003cli\u003e5.5mm collet size for precise tool clamping\u003c\/li\u003e\n\u003cli\u003eTIR of 0.005mm for high-accuracy machining\u003c\/li\u003e\n\u003cli\u003eThrough-coolant capable for improved tool life and chip removal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement collet for ER16 series collet chucks used in standard CNC and manual machining applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or toolroom technicians. Power down and lock out the machine spindle before inserting or removing the collet. Seat the collet fully into the ER16 collet nut before threading the nut onto the chuck body. Inspect the collet bore and chuck taper for debris or damage before each use to maintain rated TIR performance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Size\u003c\/strong\u003e: 5.5mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 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: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 04216-05.5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TECHNIKS","offers":[{"title":"Default Title","offer_id":51980447678770,"sku":"04216-05.5","price":47.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d6e670015579a48517661d3bb2d5b18a_a454baa7-67bb-4d27-a999-330e69b0519f.jpg?v=1789981547","url":"https:\/\/voomisupply.com\/products\/techniks-04216-05-5-er16-collet-5-5mm","provider":"Voomi Supply","version":"1.0","type":"link"}
