It accepts a nominal collet size of 0.3543 inches (9.00 mm) with a minimum collet capacity of 0.315 inches (8.0 mm), giving toolholding flexibility within the ER25 range. Total indicator runout (TIR) is rated at 0.0002 inches, supporting tight-tolerance machining where concentricity matters. Overall length is 1.338 inches. At 0.25 pounds, this is a standard-weight collet suitable for high-speed spindle use in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis collet is used in ER25-compatible toolholding chucks mounted in machining centers, CNC lathes, drill presses, and manual mills. It is appropriate for both production environments and precision repair or prototype work where accurate tool concentricity is required. Machinists and CNC operators working with metric or fractional tooling in the 8.0 mm to 9.0 mm range will find this collet fits standard ER25 chuck bodies without modification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER25 collet series  -  fits standard ER25 chuck bodies\u003c\/li\u003e\n  \u003cli\u003eNominal collet size of 0.3543 inches (9.00 mm)\u003c\/li\u003e\n  \u003cli\u003eMinimum collet capacity of 0.315 inches (8.0 mm) for flexible toolholding range\u003c\/li\u003e\n  \u003cli\u003e0.0002 inches TIR for high-concentricity, tight-tolerance applications\u003c\/li\u003e\n  \u003cli\u003eOverall length of 1.338 inches for compact spindle fitment\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.25 pounds  -  suitable for high-speed spindle operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit collet for ER25-compatible chuck bodies used in CNC machining centers, manual mills, and drill press toolholding systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator with the spindle fully stopped and power locked out before handling toolholding components. Seat the collet fully into the ER25 chuck nut before engaging the chuck body to avoid damage to the collet taper. Clean the chuck bore and collet taper surfaces before installation to ensure proper seating and accurate TIR. Follow machine manufacturer torque guidance for the ER25 nut  -  do not overtighten.\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\u003c\/strong\u003e: 0.3543 inches (9.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 0.315 inches (8.0 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\u003eOverall Diameter\u003c\/strong\u003e: 1.023 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: 5UMER25-0354\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARLEC","offers":[{"title":"Default Title","offer_id":52108599001394,"sku":"5UMER25-0354","price":81.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4116d808f6a16e468e2c155d8b913456_bf699675-9f91-405b-acc0-45436325fb07.jpg?v=1790075002","url":"https:\/\/voomisupply.com\/products\/parlec-5umer25-0354-er25-collet-0-3543in-9mm","provider":"Voomi Supply","version":"1.0","type":"link"}
