It features an MT2 inside taper and an MT4 outside taper, allowing MT2-shank tooling to seat securely in an MT4 spindle bore. The sleeve is hardened and ground throughout for dimensional accuracy and long service life. Overall length is 4-7\/8 inches with a 1\/4 inch projection. Machinists, toolroom technicians, and machine tool operators install this sleeve in drill presses, lathes, milling machines, and similar equipment where taper-size mismatch would otherwise prevent tool seating.\u003c\/p\u003e\u003cp\u003eThis reducing sleeve is suited for shop environments running mixed tooling inventories where a single spindle must accept multiple taper sizes. Typical applications include adapting MT2 drill chucks, end mill holders, or live centers into MT4 spindle receivers without reboring or retooling the machine. The hardened and ground construction ensures consistent taper-to-taper contact, minimizing runout during cutting or drilling operations. It is appropriate for both production shops and toolroom use where precise spindle adaptation is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMT2 inside taper accepts standard MT2-shank tooling\u003c\/li\u003e\n\u003cli\u003eMT4 outside taper seats directly in MT4 spindle bores\u003c\/li\u003e\n\u003cli\u003eHardened and ground throughout for accuracy and wear resistance\u003c\/li\u003e\n\u003cli\u003e4-7\/8 inch overall length with 1\/4 inch projection\u003c\/li\u003e\n\u003cli\u003eStandard reducing sleeve form factor for straightforward spindle adaptation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard OEM-style reducing sleeve for machine tool spindles with an MT4 bore that require MT2-shank tooling compatibility.

Before inserting or removing the sleeve, ensure the machine spindle is fully powered down and the drawbar or retention mechanism is released. Clean both the spindle bore and the outside taper of the sleeve thoroughly before seating to prevent false seating or runout. Drive and drift key procedures should follow the machine tool manufacturer's guidelines to avoid damage to the taper surfaces.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Taper Size\u003c\/strong\u003e: MT2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Taper Size\u003c\/strong\u003e: MT4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 1\/4 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: 1.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CR04200000MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738900169010,"sku":"CR04200000MSC","price":55.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/faee599fecd2e7a4562eea9f108c8768.jpg?v=1788806472","url":"https:\/\/voomisupply.com\/products\/accupro-cr04200000msc-mt2-inside-mt4-outside-reducing-sleeve","provider":"Voomi Supply","version":"1.0","type":"link"}
