Built to a 6mm collet size with a total indicator runout (TIR) of 0.0002 inches (0.0050mm), it delivers the concentricity required for tight-tolerance work. Through-coolant capability allows cutting fluid to pass directly through the collet to the tool tip, supporting higher cutting speeds and longer tool life. This collet is installed by machinists and CNC technicians working in production and job-shop environments where accurate, repeatable tool holding is essential.\u003c\/p\u003e\u003cp\u003eThe 04225-06 is suited for use in residential shop, production floor, and industrial machining environments. It fits ER25-compatible collet chucks and toolholders commonly found on vertical and horizontal machining centers, CNC lathes with live tooling, and high-speed routing setups. The through-coolant design makes it particularly well matched to deep-pocket milling, drilling, and reaming operations where flood coolant alone does not adequately reach the cutting zone.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER25 collet series for broad compatibility with ER25 toolholding systems\u003c\/li\u003e\n\u003cli\u003e6mm collet size for accurate clamping of 6mm shank tooling\u003c\/li\u003e\n\u003cli\u003eTIR of 0.0002 inches (0.0050mm) for high-precision concentricity\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design delivers coolant directly to the cutting edge\u003c\/li\u003e\n\u003cli\u003eCompact, standardized ER profile for quick collet changes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard fitment collet for ER25-compatible collet chucks and toolholders accepting a 6mm collet size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a qualified machinist or CNC technician. Ensure the spindle is fully stopped and the machine is in an energy-isolated state before changing collets. Seat the collet into the nut before threading onto the chuck body, and tighten to the toolholder specification using an appropriate ER collet wrench. Inspect the collet bore and seating surfaces for chips or debris before each installation to maintain TIR performance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Size\u003c\/strong\u003e: 6mm\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\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\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: 04225-06\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TECHNIKS","offers":[{"title":"Default Title","offer_id":52041541779762,"sku":"04225-06","price":40.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/83779122ed7f712d43da82eebcd38f75_58136494-304f-465a-ad78-17451b29d2ba.jpg?v=1790027788","url":"https:\/\/voomisupply.com\/products\/techniks-04225-06-er25-collet-6mm-through-coolant","provider":"Voomi Supply","version":"1.0","type":"link"}
