The sleeve accepts a 1.25-inch bore diameter and mounts to a 1.5-inch shank diameter, providing a stable, concentric adapter interface between the bar and toolholder. Overall length is 2.519 inches, with a head diameter of 1.811 inches and a body length of 2.283 inches. The unit weighs 1 pound. This accessory is typically installed by machinists and toolroom technicians working in metal-cutting environments where boring bar size adaptation is required.\u003c\/p\u003e\u003cp\u003eThis boring bar sleeve is suited for precision boring applications in job shops, production machining facilities, and tool rooms. It is used when a smaller-diameter boring bar must be held securely in a larger toolholder or spindle interface. The 1.25-inch bore depth of 1.25 inches ensures adequate bar engagement for rigid, chatter-resistant cutting. Compatible with horizontal and vertical machining setups where a 1.5-inch shank interface is present.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.25-inch bore diameter accommodates standard 1-1\/4-inch boring bars\u003c\/li\u003e\n\u003cli\u003e1.5-inch shank diameter fits common toolholder and spindle interfaces\u003c\/li\u003e\n\u003cli\u003e2.519-inch overall length with 2.283-inch body length for solid tool engagement\u003c\/li\u003e\n\u003cli\u003e1.811-inch head diameter provides a positive stop and stable seating surface\u003c\/li\u003e\n\u003cli\u003eCompact, single-piece sleeve construction at 1 pound for easy handling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement sleeve for boring bar setups requiring a 1.25-inch bore diameter and a 1.5-inch shank diameter interface in precision machining applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Before mounting or removing the sleeve, ensure the machine spindle is fully stopped and locked out per applicable machine-specific lockout\/tagout procedures. Verify bore and shank surfaces are clean and free of chips or burrs before seating the boring bar. Follow the toolholder manufacturer torque and clamping guidelines when securing the sleeve in the holder.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.519 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 2.283 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1.811 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Depth\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4505826\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51739797029170,"sku":"4505826","price":244.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/91bb23c86501e7b0826712efb43c677e_6bab6f9f-7698-4de1-9fec-7251f8af162f.jpg?v=1788818956","url":"https:\/\/voomisupply.com\/products\/iscar-4505826-boring-bar-sleeve-1-25in-bore-1-5in-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
