The adapter accepts an MT4 inside taper and presents an MT4 outside taper, allowing machinists to add axial length between the machine and the cutting tool or live center. Constructed from medium carbon steel that has been hardened and ground throughout, this adapter delivers the rigidity and surface accuracy required for reliable taper engagement. Overall length is 10.5 inches, and the unit weighs 6 pounds.\u003c\/p\u003e\n\u003cp\u003eThis extension adapter is suited for use on manual and CNC lathes, milling machines, and drill presses equipped with MT4 spindle bores or tailstock quills. Typical applications include extending the reach for deep-bore drilling operations, accommodating longer workpieces, or gaining clearance when standard tooling falls short. It is installed by machinists and toolroom technicians working in production, job shop, and maintenance environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMT4 inside taper and MT4 outside taper configuration for same-size taper extension\u003c\/li\u003e\n  \u003cli\u003eHardened and ground throughout for precise taper fit and long service life\u003c\/li\u003e\n  \u003cli\u003eMedium carbon steel construction provides strength and resistance to deformation under load\u003c\/li\u003e\n  \u003cli\u003e10.5 inch overall length adds substantial reach without sacrificing taper engagement\u003c\/li\u003e\n  \u003cli\u003eAdapter type: Morse Taper to Morse Taper for direct spindle or tailstock use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style extension adapter for machine tools equipped with MT4 spindle or tailstock bores, including lathes, milling machines, and drill presses that accept standard Morse taper tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine before inserting or removing any taper tooling. Clean both the adapter taper shanks and the receiving bore thoroughly before seating to ensure full taper contact and prevent fretting. Use a proper drift and soft-faced mallet to remove the adapter from the spindle or tailstock; never strike the cutting tool end directly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdapter Type\u003c\/strong\u003e: Morse Taper to Morse Taper\u003c\/li\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: MT4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 10.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Medium Carbon Steel\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: 6 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SC00187443\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689411903794,"sku":"SC00187443","price":52.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5a1c7c713c726c405c510e658e30df29.jpg?v=1788259060","url":"https:\/\/voomisupply.com\/products\/value-collection-sc00187443-mt4-morse-taper-extension-adapter","provider":"Voomi Supply","version":"1.0","type":"link"}
