It accepts a 25 mm shank tool and provides a secure, concentric grip for drilling, reaming, and milling operations. The collet measures 1.811 inches overall length with a 1.614-inch overall diameter and is engineered to deliver consistent clamping force at up to 1800 psi clamping pressure. Machinists and tool-room technicians rely on this style of collet for repeatable tool holding in high-cycle production environments.\u003c\/p\u003e\n\u003cp\u003eThis collet is suited for use in any standard ER40 collet chuck, making it a common replacement or additional-capacity item in CNC shops, job shops, and toolrooms running 25 mm tooling. It fits both vertical and horizontal machining center spindles as well as lathe collet chuck adapters that accept the ER40 series. Installation requires a compatible ER40 nut and chuck body.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER40 collet series for use with standard ER40 chucks and nuts\u003c\/li\u003e\n  \u003cli\u003e25 mm collet size for secure clamping of 25 mm shank tooling\u003c\/li\u003e\n  \u003cli\u003e1.811-inch overall length for proper seating in ER40 chuck bodies\u003c\/li\u003e\n  \u003cli\u003e1800 psi clamping pressure rating for reliable tool retention\u003c\/li\u003e\n  \u003cli\u003e1.614-inch overall diameter consistent with ER40 series geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or production-use collet for any standard ER40 collet chuck system accepting 25 mm tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or tool-room technicians. Always ensure the spindle or chuck is fully stopped and the machine is powered down before changing collets. Seat the collet fully into the ER40 nut before threading the assembly onto the chuck body, and torque the nut with a proper ER spanner wrench to the chuck manufacturer specification. Inspect the collet bore and seating taper for chips or debris before each use to maintain runout accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Size\u003c\/strong\u003e: 25 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.811 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 1.614 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: 0.4 pounds\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: PARLEC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ERS40-0984\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARLEC","offers":[{"title":"Default Title","offer_id":52060179235122,"sku":"ERS40-0984","price":76.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/87e60de3afca3b8987c98b40590c8602.jpg?v=1790040923","url":"https:\/\/voomisupply.com\/products\/parlec-ers40-0984-er40-collet-25-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
