It delivers a total indicated runout (TIR) of 0.01 mm (0.000394 inches), providing the precision required for milling, drilling, reaming, and tapping applications. The collet measures 27 mm overall length with a 17 mm overall diameter. ER16 collets are a standard workholding component used by machinists and CNC operators in production and job-shop environments. This collet is installed and serviced by qualified machine tool operators or toolroom technicians following established toolholder maintenance procedures.\u003c\/p\u003e\n\u003cp\u003eThe SECO 75042068 is suited for use in CNC machining centers, manual milling machines, and drilling equipment that accept ER16 collet chucks. It is appropriate for light to medium cutting operations where accurate tool concentricity is required. Typical applications include production milling, precision drilling, and high-speed spindle work where consistent TIR performance directly affects surface finish and tool life. This collet does not support through-coolant delivery.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER16 collet series with 6 mm bore for standard metric tooling\u003c\/li\u003e\n  \u003cli\u003e0.01 mm TIR for consistent tool concentricity\u003c\/li\u003e\n  \u003cli\u003e27 mm overall length fits standard ER16 collet chuck depth requirements\u003c\/li\u003e\n  \u003cli\u003e17 mm overall diameter\u003c\/li\u003e\n  \u003cli\u003eNo through-coolant configuration — suited for dry or flood coolant setups\u003c\/li\u003e\n  \u003cli\u003eSold individually (package quantity of 1)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement collet for use in standard ER16 collet chuck systems accepting 6 mm bore collets.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eER16 collets are installed and removed by qualified machine tool operators or toolroom technicians. Power down and de-energize the spindle drive completely before changing collets. Use a proper ER collet nut and torque wrench rated for ER16 systems — never use an impact wrench on collet nuts. Inspect the collet bore and chuck taper for chips or damage before seating the collet to avoid compromised runout.\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 Bore Size\u003c\/strong\u003e: 6 mm (0.2360 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.01 mm (0.000394 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 27 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 17 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.1 inches L x 1.5 inches W x 1.5 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 75042068\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563865604402,"sku":"75042068","price":70.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/24abcf4c4b3518224b2ad1e529a7d4c7.jpg?v=1786505427","url":"https:\/\/voomisupply.com\/products\/seco-75042068-er16-collet-6-mm-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
