It features a C6 modular connection shank, which interfaces with compatible tooling systems for quick, repeatable tool changes without loss of concentricity. The chuck accepts a 20 mm bore, delivers an 84 mm projection from the gauge line, and is balanced to 20,000 RPM, making it suitable for high-speed milling and drilling operations. Through-coolant capability allows cutting fluid to reach the tool tip directly, improving chip evacuation and extending tool life in demanding materials.\u003c\/p\u003e\n\u003cp\u003eThis hydraulic chuck is intended for use in production machining environments where runout control and vibration damping are critical. The hydraulic clamping mechanism distributes clamping force evenly around the tool shank, reducing micro-vibration compared to collet-style holders. Typical applications include finish milling, reaming, and drilling in automotive, aerospace, and general precision components. The 36 mm clamping depth ensures a secure grip on standard-length tool shanks within the 20 mm bore diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eC6 modular connection shank for fast, repeatable tool changes on compatible machining centers\u003c\/li\u003e\n  \u003cli\u003eHydraulic clamping mechanism provides even radial force for low runout and vibration damping\u003c\/li\u003e\n  \u003cli\u003eBalanced to 20,000 RPM for high-speed cutting operations\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design channels fluid directly to the cutting zone\u003c\/li\u003e\n  \u003cli\u003e36 mm clamping depth secures standard shank tools in the 20 mm bore\u003c\/li\u003e\n  \u003cli\u003e50 mm nose diameter with 84 mm projection suits a wide range of reach requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with C6 modular tooling interfaces on compatible CNC machining centers.

Ensure the machine spindle and C6 receiver are clean and free of chips or debris before mounting. Disengage spindle drive and confirm the machine is in a safe, powered-down state before any toolholder exchange. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when pressurizing the hydraulic clamping mechanism.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: C6 Modular Connection\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 20 mm (0.7874 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClamping Depth\u003c\/strong\u003e: 36 mm (1.6142 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 84 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 122 mm (4.8031 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 50 mm (1.9685 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBalanced To\u003c\/strong\u003e: 20,000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.89 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: 6255453\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51728495608114,"sku":"6255453","price":1196.83,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/91fa783f0c0c6448992cb85dee19400a.jpg?v=1788692157","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-6255453-hydraulic-tool-chuck-c6-20mm","provider":"Voomi Supply","version":"1.0","type":"link"}
