With a nominal collet size of 0.625 inches and a total indicator runout (TIR) of 0.0005 inches, this collet delivers the tight tolerances required for accurate material removal and repeatable tool positioning. It is manufactured to fit standard ER25 collet chucks and is suitable for holding round-shank cutting tools, drill bits, and end mills. Machinists and toolroom technicians rely on this type of collet for consistent performance across production and maintenance machining tasks.\u003c\/p\u003e\n\u003cp\u003eThis collet is intended for use in ER25-compatible collet chucks mounted on CNC machining centers, manual knee mills, lathes with live tooling, and drill presses that accept ER-series toolholding systems. The 0.625-inch bore accommodates 5\/8-inch shank tooling, which is common in general-purpose and heavy-duty cutting operations. It is appropriate for both production shop environments and toolroom use where dimensional accuracy and runout control are critical to finished-part quality.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER25 collet series for compatibility with standard ER25 chucks and collet nuts\u003c\/li\u003e\n  \u003cli\u003e0.625-inch (5\/8-inch) bore size for common cutting tool shank diameters\u003c\/li\u003e\n  \u003cli\u003e0.0005-inch TIR for precise tool concentricity and reduced vibration during cutting\u003c\/li\u003e\n  \u003cli\u003eSold individually, allowing single-unit replacement or incremental set building\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ER25-series collet chucks that accept standard ER25 collets with a 0.625-inch bore capacity.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolroom technicians using an appropriate ER25 collet nut and spanner wrench. Before changing collets, ensure the spindle is fully stopped and the machine is locked out per applicable safety procedures. Seat the collet fully into the collet nut before threading onto the chuck body to avoid cross-threading or collet damage. Torque the collet nut with a calibrated spanner to the chuck manufacturer's specification — do not overtighten or use improvised tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Size (Decimal Inch)\u003c\/strong\u003e: 0.6250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Size (Fraction)\u003c\/strong\u003e: 5\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTotal Indicator Runout (TIR)\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.352 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 204-2550\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698406916402,"sku":"204-2550","price":411.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/82cace1eef090ba246d86b8a16603de3.jpg?v=1788362368","url":"https:\/\/voomisupply.com\/products\/value-collection-204-2550-er25-collet-0-625-in","provider":"Voomi Supply","version":"1.0","type":"link"}
