With a collet size of 0.079 inches (2.00mm), it provides a secure clamping grip on small-diameter cutting tools including end mills, drills, and reamers. The 04216-02 features through-coolant capability, allowing coolant to pass directly through the collet to the cutting zone for improved chip evacuation and tool life. Total indicator runout (TIR) is rated at 0.005mm, supporting accurate, repeatable cuts in precision machining environments. Machinists and CNC operators working in production shops or tool rooms are the primary installers of this collet.\u003c\/p\u003e\n\u003cp\u003eThis ER16 collet is suited for light-duty and precision machining applications where small-diameter tooling is required. The ER16 series is one of the most widely used collet standards in CNC milling and high-speed routing. It fits any ER16-compatible collet chuck or toolholder. Typical applications include precision drilling, light profiling, and finish milling with small-diameter end mills in both ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER16 series collet accepting 0.079 inch (2.00mm) tool shanks\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design directs coolant to the cutting edge for improved tool life and chip removal\u003c\/li\u003e\n  \u003cli\u003eTIR of 0.005mm for high-accuracy, low-runout performance\u003c\/li\u003e\n  \u003cli\u003eCompact ER16 form factor compatible with standard ER16 collet chucks and toolholders\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.075 pounds for minimal toolholder imbalance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to fit standard ER16-compatible collet chucks and toolholding systems.

Always ensure the machine spindle is fully stopped and the tool is locked out before changing collets. Clean the collet, nut, and chuck bore of chips and coolant residue before seating the collet to ensure proper runout and clamping force. Use the appropriate ER16 collet nut and torque wrench rated for ER-series tooling to avoid over-tightening or under-tightening the collet nut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Size (Decimal Inch)\u003c\/strong\u003e: 0.079 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Size (mm)\u003c\/strong\u003e: 2.00mm\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: 0.005mm\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\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: 04216-02\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TECHNIKS","offers":[{"title":"Default Title","offer_id":52014935540018,"sku":"04216-02","price":46.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cfe4d9cce363bbe8a9264f72e07a1262.jpg?v=1790007358","url":"https:\/\/voomisupply.com\/products\/techniks-04216-02-er16-collet-0-079-inch-through-coolant","provider":"Voomi Supply","version":"1.0","type":"link"}
