It delivers a total indicator runout (TIR) of 0.0004 inches, providing the concentricity needed for precision toolholding in light milling, drilling, and engraving operations. Weighing 0.08 pounds, this collet is a compact, single-piece holding solution designed for machinists and toolroom technicians working with small-diameter tooling where accuracy is critical.\u003c\/p\u003e\u003cp\u003eThis collet is suited for use in residential and commercial machine shop environments, as well as production and toolroom settings where ER11 chuck systems are already in service. It is a practical fit for applications involving small end mills, drills, reamers, or engraving bits with a 5\/32-inch shank. No through-coolant feature is present, making it appropriate for dry or flood-coolant operations where internal coolant delivery is not required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER11 collet series for compatibility with standard ER11 chucks\u003c\/li\u003e\n\u003cli\u003e0.1562-inch (5\/32-inch) bore size for precise small-diameter toolholding\u003c\/li\u003e\n\u003cli\u003eTIR of 0.0004 inches for tight concentricity in precision machining\u003c\/li\u003e\n\u003cli\u003eNo through-coolant design suits dry and standard flood-coolant setups\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.08 pounds for minimal spindle load impact\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard addition for ER11 collet chuck systems used in CNC and manual spindle applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a qualified machinist or toolroom technician. Before inserting or removing a collet, ensure the spindle is fully stopped and all power to the machine is off. Use the appropriate ER11 collet nut and chuck wrench to seat and torque the collet correctly per the machine manufacturer's guidelines. Inspect the collet bore and chuck taper for debris or damage before each use to maintain concentricity and tool life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Size (Decimal Inch)\u003c\/strong\u003e: 0.1562 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Size (Fractional Inch)\u003c\/strong\u003e: 5\/32 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: 0.08 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: ER11-156\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MICRO 100","offers":[{"title":"Default Title","offer_id":51973607883058,"sku":"ER11-156","price":36.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e431c924ec1dcbc47a17a70a81dd8b97_69350e30-b268-44d4-a746-3b830c1f4d01.jpg?v=1789973838","url":"https:\/\/voomisupply.com\/products\/micro-100-er11-156-er11-er-collet-5-32-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
