It accepts a 1 mm clamping diameter and features through-coolant capability, allowing coolant to pass directly through the collet to the cutting tool. The collet holds a total indicator runout (TIR) of 0.005 mm, making it suitable for high-precision drilling, milling, and reaming operations. This collet is installed by machinists and CNC technicians working with ER16-compatible collet chucks on machining centers, lathes, and manual mills.\u003c\/p\u003e\u003cp\u003eThe 04216-01 is intended for use in light-duty to medium-duty machining environments where small-diameter tooling requires secure, accurate clamping. The 1 mm capacity suits micro-tooling applications such as fine drilling, engraving, and precision milling. Through-coolant support makes it appropriate for deep-hole drilling and high-speed operations where direct coolant delivery to the cutting edge reduces heat and extends tool life.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER16 collet series for use with standard ER16 collet chucks\u003c\/li\u003e\n\u003cli\u003e1 mm clamping diameter for micro and small-diameter tooling\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design directs coolant flow to the cutting tool\u003c\/li\u003e\n\u003cli\u003e0.005 mm TIR for high-precision runout control\u003c\/li\u003e\n\u003cli\u003eCompact form factor suited for high-speed spindle applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard ER16-series collet compatible with ER16 collet chucks used on CNC machining centers, milling machines, lathes, and similar toolholding equipment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eER collets are installed by machinists or CNC technicians into ER16-compatible collet chucks using the appropriate collet nut and spanner wrench. Ensure the chuck and spindle are fully stopped and the machine is powered down before inserting or removing collets. Inspect the collet bore and chuck taper for debris or damage before installation, as contamination directly affects runout and clamping force. Do not exceed the collet clamping range for the selected tool diameter.\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\u003eClamping Diameter\u003c\/strong\u003e: 1 mm\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: 0.005 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.075 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: 04216-01\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TECHNIKS","offers":[{"title":"Default Title","offer_id":52086700802354,"sku":"04216-01","price":58.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/08f44fc29777aface5d6f2ae2753a6b0.jpg?v=1790059841","url":"https:\/\/voomisupply.com\/products\/techniks-04216-01-er16-collet-1-mm-through-coolant","provider":"Voomi Supply","version":"1.0","type":"link"}
