This collet holds workpieces or cutting tools up to 0.748 inches (19.00 mm) in diameter, with a minimum collet capacity of 0.708 inches (18.00 mm), providing a clamping range of 0.040 inches. Total Indicated Runout (TIR) is rated at 0.01 mm, making it suitable for precision toolholding applications where concentricity directly affects surface finish and tool life. Machinists and toolroom technicians working in production or job-shop environments rely on consistent TIR specifications to maintain tight tolerances across repeated setups.\u003c\/p\u003e\u003cp\u003eThis collet is used in any machine spindle or toolholder that accepts the ER32 collet format, one of the most widely adopted collet systems in industrial machining. Typical applications include end mill holding, drill chuck replacement, reaming, and tapping operations on vertical machining centers and manual knee mills. The ER32 form factor is common in both production and maintenance machining environments across a broad range of industries.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER32 collet series for broad spindle and toolholder compatibility\u003c\/li\u003e\n\u003cli\u003e0.748 inch (19.00 mm) maximum collet capacity\u003c\/li\u003e\n\u003cli\u003e0.708 inch (18.00 mm) minimum collet capacity for a 0.040 inch clamping range\u003c\/li\u003e\n\u003cli\u003e0.01 mm TIR rating for precision concentricity in toolholding applications\u003c\/li\u003e\n\u003cli\u003eSingle-piece unit packaged individually for direct replacement or inventory replenishment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in any spindle, toolholder, or collet chuck that accepts the ER32 collet standard. Verify that the host toolholder or machine spindle is rated for the ER32 form factor before installation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Always power down and lock out the machine spindle before inserting or removing a collet. Seat the collet fully in the collet nut before threading the nut onto the toolholder body, and torque the nut with the appropriate ER collet wrench to manufacturer specification. Inspect the collet bore and seating surfaces for chips or debris before each use, as contamination directly degrades TIR performance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Collet Capacity\u003c\/strong\u003e: 0.748 inches (19.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 0.708 inches (18.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.01 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 587377\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51746471674162,"sku":"587377","price":35.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/93083b9ff060d4b97eae34ed72fe844f.jpg?v=1788870633","url":"https:\/\/voomisupply.com\/products\/accupro-587377-er32-collet-0-748-inch-0-01mm-tir","provider":"Voomi Supply","version":"1.0","type":"link"}
