The sleeve is hardened and ground throughout for dimensional accuracy and long service life under machining loads. It features a 0.75 inch projection, a body diameter of 48 millimeters, and an overall length of 300 millimeters. Machinists and tool room technicians install this sleeve directly into MT5-tapered spindles, quills, or tailstocks to run MT4 drills, reamers, arbors, and other taper-shank cutting tools without an adapter change-out on the machine itself.\u003c\/p\u003e\u003cp\u003eThis reducing sleeve is suited for manual lathes, milling machines, drill presses, and boring mills equipped with an MT5 taper. It is a common shop-floor solution when a machine tool has a larger taper than the tooling requires. The hardened and ground construction maintains close taper tolerances, which reduces runout and keeps tool seating repeatable across multiple tool changes. It is intended for general metalworking applications in both production and job-shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMT4 inside taper accepts standard MT4 taper-shank tooling\u003c\/li\u003e\n\u003cli\u003eMT5 outside taper seats directly into MT5 spindles, quills, and tailstocks\u003c\/li\u003e\n\u003cli\u003eHardened and ground throughout for close tolerances and reduced runout\u003c\/li\u003e\n\u003cli\u003e0.75 inch projection for proper tool engagement and drift-key ejection clearance\u003c\/li\u003e\n\u003cli\u003e48 millimeter body diameter provides robust wall thickness for rigidity under load\u003c\/li\u003e\n\u003cli\u003e300 millimeter overall length suits deep-reach and standard spindle applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard OEM-style reducing sleeve for machine tools equipped with an MT5 taper spindle, quill, or tailstock requiring MT4 taper-shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or tool room technicians. Power down and lock out the machine before seating or removing the sleeve. Clean both the MT5 socket and the outside taper of the sleeve with a lint-free cloth to remove oil, chips, and debris before insertion, as contamination will cause misalignment and runout. Use the machine drift key slot and a proper drift key to eject the sleeve; never strike the tooling directly with a hammer.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Taper Size\u003c\/strong\u003e: MT4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Taper Size\u003c\/strong\u003e: MT5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 300 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 48 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Features\u003c\/strong\u003e: Hardened and Ground Throughout\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.41 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 214-8145\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692625887538,"sku":"214-8145","price":48.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e9c4bd0d9d693f2556cdfda884a126b1.jpg?v=1788300209","url":"https:\/\/voomisupply.com\/products\/value-collection-214-8145-mt4-inside-mt5-outside-reducing-sleeve","provider":"Voomi Supply","version":"1.0","type":"link"}
