It holds tool shanks up to 0.312 inches in diameter and closes down to a minimum collet capacity of 0.273 inches, giving it a clamping range suited for a variety of end mills, drills, and other round-shank cutting tools. Overall length is 1.338 inches. This collet is installed by machinists and CNC setup technicians as part of a standard ER toolholding assembly.\u003c\/p\u003e\n\u003cp\u003eThis collet is used in production and job-shop environments where ER25-compatible toolholders are standard. It fits any ER25 collet chuck or toolholder nut that conforms to the ER25 specification. Typical applications include milling, drilling, reaming, and tapping operations on CNC and manual machines. The 0.312-inch capacity makes it a common choice for fractional-shank tooling in both light and medium-duty cutting operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER25 collet series for use with ER25-compatible toolholders and nuts\u003c\/li\u003e\n  \u003cli\u003eMaximum collet capacity of 0.312 inches for fractional-shank tooling\u003c\/li\u003e\n  \u003cli\u003eMinimum collet capacity of 0.273 inches for a clamping range within the series standard\u003c\/li\u003e\n  \u003cli\u003eOverall length of 1.338 inches for compact toolholding assemblies\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds for easy handling during tool changes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit collet for ER25-series collet chucks and toolholders conforming to the ER25 standard specification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or CNC tooling technicians. Power down and lock out the spindle before changing collets. Seat the collet fully into the ER collet nut before threading the nut onto the toolholder body, and use a calibrated ER torque wrench to tighten to the toolholder specification. Inspect the collet bore and seating surfaces for chips or debris before installation to ensure proper runout performance.\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\u003eMaximum Collet Capacity\u003c\/strong\u003e: 0.312 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 0.273 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.338 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: ER25-0312\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARLEC","offers":[{"title":"Default Title","offer_id":52062253023538,"sku":"ER25-0312","price":49.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9bc3beac1d9ca501f458849e4908d599.jpg?v=1790042337","url":"https:\/\/voomisupply.com\/products\/parlec-er25-0312-er25-collet-0-312-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
