The chuck accepts the full range of ER25 collets and features through-coolant capability for direct coolant delivery to the cutting zone. With a projection of 1.4961 inches and a nose diameter of 1.6535 inches, it is balanced to 39,000 RPM, making it suitable for high-speed machining operations. Installation and removal are performed with a standard ER wrench. This chuck is intended for use by professional machinists and toolroom technicians in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis chuck is suited for high-speed milling, drilling, reaming, and tapping operations where accurate tool runout and coolant delivery are required. The C4 modular connection shank allows quick changeover on machines equipped with a compatible Coromant Capto or equivalent modular tooling system. The 1.4961-inch projection and 2.4409-inch overall length keep gauge-line distances manageable in tight workholding setups. Through-coolant passages support chip evacuation and tool life in deep-hole and high-feed applications on both horizontal and vertical machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER25 collet system accepts a wide range of ER25 collet bore sizes for versatile toolholding\u003c\/li\u003e\n  \u003cli\u003eC4 modular connection shank enables fast, repeatable tool changes on compatible machine interfaces\u003c\/li\u003e\n  \u003cli\u003eBalanced to 39,000 RPM for stable performance in high-speed machining applications\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant capability delivers coolant directly to the cutting edge\u003c\/li\u003e\n  \u003cli\u003e1.4961-inch projection and 2.4409-inch overall length suit compact workholding setups\u003c\/li\u003e\n  \u003cli\u003eActuated by standard ER wrench — no special tooling required for collet changes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ER25 collets on CNC machining centers and turning centers equipped with a C4 modular connection interface.

Ensure the machine spindle and all tooling interfaces are clean and free of chips or debris before assembly. Torque the collet nut to the toolholder manufacturer's specification using the correct ER25 spanner wrench — do not use pipe wrenches or improvised tools. Verify runout after assembly and before initiating any cutting cycle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet System\u003c\/strong\u003e: ER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Modular Connection\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eModular Connection Size\u003c\/strong\u003e: C4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 1.4961 inches (38.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.4409 inches (62.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 1.6535 inches (42.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBalance Speed\u003c\/strong\u003e: 39,000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Type\u003c\/strong\u003e: Wrench\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.65 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: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5728002\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51738724303154,"sku":"5728002","price":639.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/638cdf5a939a708a1dd254e56e2c5cbe_bb7d81e6-a45c-4cfa-8365-e5146389a383.jpg?v=1788803450","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5728002-er25-collet-chuck-c4-modular","provider":"Voomi Supply","version":"1.0","type":"link"}
