It is used in machine tool spindles and tailstocks to allow smaller-shank tooling to seat securely in larger-bore holders. The sleeve features a soft body with a hardened tang, which provides durability at the drive point while keeping the sleeve body machinable if needed. Overall length is 4-7\/8 inches with a 1\/4-inch projection. Machinists and machine tool technicians install this type of sleeve during tooling changeovers on lathes, drill presses, and milling machines.\u003c\/p\u003e\n\u003cp\u003eThis reducing sleeve is suited for machine shop environments where MT1-shank tooling such as small drill chucks, centers, or reamers must be mounted in a spindle or tailstock bored to MT4. It is appropriate for both manual and CNC machine tools that accept Morse taper tooling. The hardened tang engages the drift slot in the spindle for positive retention and clean removal. Typical users include machinists, tool and die makers, and maintenance technicians working with general-purpose or production machine tools.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMT1 inside taper accepts standard MT1-shank tooling directly\u003c\/li\u003e\n  \u003cli\u003eMT4 outside taper seats in MT4-bore spindles and tailstocks\u003c\/li\u003e\n  \u003cli\u003eSoft body with hardened tang for durability at the drive and ejection point\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 tooling changeovers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style reducing sleeve for machine tool spindles and tailstocks with an MT4-bore that require MT1-shank tooling capability.

Before inserting or removing any taper sleeve, power down the machine and confirm the spindle is fully stopped. Clean both the sleeve taper and the spindle bore with a lint-free cloth before seating to ensure full taper contact and prevent fretting. Use a proper Morse taper drift through the spindle drift slot to remove the sleeve cleanly without damaging the taper surfaces.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: Soft with Hardened Tang\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.18 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: CRS410000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51734839165234,"sku":"CRS410000","price":66.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da67e9f033aa3dfa3dd42af68af79320.jpg?v=1788767276","url":"https:\/\/voomisupply.com\/products\/accupro-crs410000-morse-taper-reducing-sleeve-mt1-mt4","provider":"Voomi Supply","version":"1.0","type":"link"}
