It fits standard ER16 collet chucks used on CNC machining centers, manual mills, lathes, and high-speed spindles. The collet delivers a total indicator runout (TIR) of 0.0004 inches, providing the concentricity required for precision milling, drilling, and reaming operations. This collet does not include through-coolant capability. It is installed by machinists and toolroom technicians in production and job-shop environments where consistent tool grip and minimal runout are critical to finished-part accuracy.\u003c\/p\u003e\u003cp\u003eThe ER16-125 is suited for use in light-duty to medium-duty machining operations where a 1\/8-inch tool shank is required. Typical applications include end milling with small-diameter end mills, drilling with jobber-length drill bits, and holding reamers or engraving bits. The ER16 form factor is widely used in compact spindle noses and collet chucks across a broad range of CNC and manual machine tool platforms.\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\u003eAccepts 0.125-inch (1\/8-inch) shank diameter tooling\u003c\/li\u003e\n\u003cli\u003eTIR of 0.0004 inches for high-concentricity tool holding\u003c\/li\u003e\n\u003cli\u003eNo through-coolant passage  -  suited for dry or flood-coolant setups\u003c\/li\u003e\n\u003cli\u003eCompact form factor compatible with small spindle nose designs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling collet for use with ER16 collet chucks on CNC machining centers, manual knee mills, and high-speed spindle units accepting the ER16 collet standard.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and removal should be performed by a qualified machinist or toolroom technician. Always power down and lock out the spindle before seating or removing a collet. Insert the collet into the nut before threading onto the chuck body  -  never press the collet directly onto the chuck taper without the nut engaged. Verify TIR with a dial test indicator after clamping to confirm acceptable runout before beginning a cut.\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\u003eCollet Size\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: MICRO 100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ER16-125\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MICRO 100","offers":[{"title":"Default Title","offer_id":52044591268146,"sku":"ER16-125","price":36.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e431c924ec1dcbc47a17a70a81dd8b97_0ca76b00-6753-4cf9-9bbb-3f6b716b0950.jpg?v=1790029972","url":"https:\/\/voomisupply.com\/products\/micro-100-er16-125-er16-collet-1-8-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
