This collet holds a nominal collet size of 1.50mm (0.059 inches) with a minimum collet capacity of 1.0mm (0.0393 inches), providing a gripping range suitable for small-diameter tooling. The overall length is 13.0mm and the overall diameter is 8.5mm. A total indicator runout (TIR) rating of 0.01mm ensures tight concentricity tolerances, making this collet appropriate for precision cutting, drilling, and engraving operations. Machinists and tool-and-die technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis ER8 collet is suited for use in compact or miniature spindle applications where small-bore collet chucks are required. Typical scenarios include high-speed engraving spindles, micro-drilling operations, and bench-top CNC machines equipped with ER8 tool-holding systems. The 0.01mm TIR rating supports precision work where runout directly affects finished part quality and tool life. The collet accommodates shank diameters from 1.0mm up to 1.50mm, giving the operator a small but usable gripping range within the ER8 standard.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER8 collet series for use with ER8-standard collet chucks and tool holders\u003c\/li\u003e\n  \u003cli\u003e1.50mm nominal collet size (0.059 inches) with gripping range down to 1.0mm (0.0393 inches)\u003c\/li\u003e\n  \u003cli\u003e0.01mm TIR for precision concentricity in micro-machining and engraving applications\u003c\/li\u003e\n  \u003cli\u003e13.0mm overall length and 8.5mm overall diameter for compact spindle fit\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.1 pounds, minimizing added mass in high-speed setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ER8-standard collet chucks and tool holders that accept the ER8 collet series. Specific chuck or spindle compatibility should be verified against the ER8 collet chuck specification for bore diameter and retention nut thread.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following the spindle or chuck manufacturer guidelines. Ensure the spindle is fully powered down and at a complete stop before inserting or removing the collet. Inspect the collet bore, taper, and retention nut for debris or wear before seating. Do not exceed the rated gripping range; using a shank diameter outside the specified capacity range can damage the collet and compromise workpiece concentricity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Collet Size\u003c\/strong\u003e: 1.50mm (0.059 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 1.0mm (0.0393 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 13.0mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 8.5mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.01mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 1.88 inches H x 1.13 inches W x 1.13 inches L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 587637\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51746800992562,"sku":"587637","price":34.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e67046d789205beba9890faa331b5acb.jpg?v=1788873699","url":"https:\/\/voomisupply.com\/products\/accupro-587637-er8-collet-1-50mm-0-059-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
