It allows a tool or accessory with an MT1 shank to seat correctly in a machine spindle or socket bored to MT4. 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, tool-room technicians, and CNC setup personnel use these sleeves during spindle setup and tooling changes on drill presses, lathes, and milling machines.\u003c\/p\u003e\u003cp\u003eMorse taper reducing sleeves are standard toolroom consumables in both production and job-shop environments. This sleeve is suited to any machine spindle that accepts an MT4 taper when the cutting tool or arbor carries an MT1 shank. Typical applications include drill press tooling setups, lathe tailstock operations, and manual milling operations where mixed taper sizes must be reconciled without a full spindle change.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMT1 inside taper to MT4 outside taper configuration for direct shank adaptation\u003c\/li\u003e\n\u003cli\u003eHardened and ground throughout for consistent taper fit and extended wear resistance\u003c\/li\u003e\n\u003cli\u003e4-7\/8 inch overall length with 1\/4 inch projection\u003c\/li\u003e\n\u003cli\u003eStandard sleeve geometry compatible with conventional Morse taper tooling systems\u003c\/li\u003e\n\u003cli\u003eSingle-piece construction with no moving parts for straightforward installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard toolroom component for machine spindles and sockets bored to MT4 that require adaptation to MT1 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 spindle before inserting or removing any taper sleeve. Ensure both the sleeve bore and the spindle socket are clean and free of chips or burrs before seating the taper, as debris will prevent full contact and can cause runout. To remove the sleeve, use the machine drift slot and a proper drift key rather than striking the sleeve directly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Taper Size\u003c\/strong\u003e: MT1\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: 1.18 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: CR04100000MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728980541746,"sku":"CR04100000MSC","price":62.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9e6800b4e8d2b4848c082065dbd55588.jpg?v=1788698371","url":"https:\/\/voomisupply.com\/products\/accupro-cr04100000msc-mt1-mt4-morse-taper-reducing-sleeve","provider":"Voomi Supply","version":"1.0","type":"link"}
