With a 4 mm bore diameter and an overall length of 1.338 inches, this collet seats into any standard ER25 collet chuck to grip cutting tools, drill bits, and round-shank tooling securely. Rated to 1800 psi clamping pressure, it delivers the holding force required for consistent, repeatable toolholding in production environments. Machinist and CNC technicians are the primary installers for this component.\u003c\/p\u003e\u003cp\u003eThis collet is suited for use in machine shops, job shops, and manufacturing facilities running ER25-compatible toolholding systems. It accommodates 4 mm shank tooling and is a standard fit across a broad range of spindle configurations that accept the ER25 collet standard. Typical applications include light milling, drilling, reaming, and tapping operations where precise tool concentricity is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER25 series collet with 4 mm bore for precise tool gripping\u003c\/li\u003e\n\u003cli\u003eOverall length of 1.338 inches for standard ER25 chuck compatibility\u003c\/li\u003e\n\u003cli\u003e1800 psi rated clamping pressure for secure toolholding\u003c\/li\u003e\n\u003cli\u003eCompact design at 0.18 pounds for easy handling and tool change\u003c\/li\u003e\n\u003cli\u003eCompatible with any standard ER25 collet nut and chuck body\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit collet for use with standard ER25 collet chucks and compatible toolholding systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is locked out before changing collets. Clean the collet taper and chuck bore before seating to prevent runout. Use the appropriate ER25 collet nut and torque wrench per the chuck manufacturer's guidelines to achieve proper clamping force.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Size\u003c\/strong\u003e: 4 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.338 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClamping Pressure\u003c\/strong\u003e: 1800 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.18 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PARLEC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ERS25-0157\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARLEC","offers":[{"title":"Default Title","offer_id":52115809599794,"sku":"ERS25-0157","price":68.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/253a2e0cc7f12f504231c8e182313a20.jpg?v=1790080212","url":"https:\/\/voomisupply.com\/products\/parlec-ers25-0157-er25-collet-4mm-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
