Built to the ER16 collet series standard, this collet accepts a 3.5 mm shank diameter with a minimum collet capacity of 2.5 mm, giving it a working range suited to small-diameter tooling. Total indicator runout (TIR) is held to 0.0152 mm (0.0006 inches), supporting accurate, repeatable tool positioning. Overall length is 27.51 mm (1.083 inches). Machinists and toolroom technicians specify this collet when tight TIR tolerances are required for drilling, reaming, or end milling operations.\u003c\/p\u003e\n\u003cp\u003eThis collet fits ER16 collet chucks used in a wide range of machining setups, including CNC machining centers, manual mills, and router spindles equipped with an ER16 nut and chuck body. The 3.5 mm capacity makes it well suited for small-diameter end mills, drills, and reamers commonly used in precision metalworking and mold-making environments. It is a direct replacement or spare collet for any ER16-compatible toolholding system where the 3.5 mm size range is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER16 collet series — fits standard ER16 chucks and clamping nuts\u003c\/li\u003e\n  \u003cli\u003e3.5 mm nominal collet capacity with a 2.5 mm minimum collet capacity\u003c\/li\u003e\n  \u003cli\u003e0.0152 mm (0.0006 inch) TIR for precise, low-runout tool holding\u003c\/li\u003e\n  \u003cli\u003e27.51 mm overall length for use in compact ER16 chuck bodies\u003c\/li\u003e\n  \u003cli\u003eSingle-piece quantity packaging — suitable for replacement or inventory replenishment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ER16 collet chucks and clamping nuts conforming to the ER16 collet series standard.

Always de-energize and lock out the machine spindle before changing collets. Insert the collet into the chuck nut before threading onto the spindle to avoid damage to the collet taper. Inspect the collet bore and chuck taper for chips or debris before assembly, as contamination will increase runout and reduce tool life.\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 Capacity\u003c\/strong\u003e: 3.5 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 2.5 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 27.51 mm (1.083 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0152 mm (0.0006 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0441 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1108458\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51744535773490,"sku":"1108458","price":71.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7406b66924e252086609b7a01238a775.jpg?v=1788857710","url":"https:\/\/voomisupply.com\/products\/kennametal-1108458-er16-collet-3-5-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
