This sleeve features a 6 mm inside diameter, 12 mm outside diameter, and a 16 mm head diameter, with a length under head of 1.5748 inches (40 mm). Constructed from steel, it supports through-coolant delivery, directing cutting fluid directly to the cutting zone to improve chip evacuation and tool life. Machinists and tooling specialists install this sleeve when sizing down a hydraulic chuck to accept smaller-shank tooling without replacing the chuck body.\u003c\/p\u003e\u003cp\u003eThis sleeve is suited for use in production machining environments where hydraulic chucks are used with small-diameter cutting tools such as end mills, drills, and reamers. It is appropriate for both light and high-speed finishing operations where concentricity and vibration damping are critical. The through-coolant feature makes it particularly useful in deep-hole drilling and high-temperature applications where flood coolant is insufficient.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e6 mm inside diameter accepts small-shank tooling in standard hydraulic chuck bodies\u003c\/li\u003e\n\u003cli\u003e12 mm outside diameter fits corresponding hydraulic chuck bore\u003c\/li\u003e\n\u003cli\u003e16 mm head diameter provides positive axial stop and seating surface\u003c\/li\u003e\n\u003cli\u003eThrough-coolant compatible for directed coolant delivery to the cutting zone\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability and dimensional stability under clamping pressure\u003c\/li\u003e\n\u003cli\u003eLength under head of 1.5748 inches (40 mm) for proper tool projection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a reduction sleeve for hydraulic chuck holders that accept a 12 mm outside diameter sleeve and require a 6 mm bore for small-shank tooling. Specific chuck body compatibility should be confirmed against the chuck manufacturer's sleeve specification chart before installation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or tooling technicians. Ensure the hydraulic chuck is fully depressurized and the machine spindle is powered off before inserting or removing the sleeve. Clean the chuck bore and sleeve exterior thoroughly to remove chips and coolant residue before seating the sleeve, as contamination can affect concentricity. Confirm sleeve seating and tool projection length before applying clamping pressure to the chuck.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 6 mm (0.2362 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 12 mm (0.4724 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 16 mm (0.6299 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1.5748 inches (40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5760239\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51732821410098,"sku":"5760239","price":230.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/529623a4c8d73a71c146d1f25e523442_ff9f9859-194b-49e8-bdb1-310105738a32.jpg?v=1788747188","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5760239-hydraulic-chuck-sleeve","provider":"Voomi Supply","version":"1.0","type":"link"}
