It accepts an MT5 inside taper and presents an MT4 outside taper, allowing a technician to extend tooling depth or adapt between two common Morse taper sizes within a drill press, lathe, or milling machine spindle. The body is constructed from medium carbon steel and features a soft shank with a hardened tang, providing resistance at the drive point where force is transferred. Overall length is 11-7\/8 inches. Machinists, tool and die technicians, and machine shop operators are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis adapter is used in machine shop and production environments where spindle tapers must be extended or matched to tooling with a different Morse taper size. Typical applications include adapting an MT4 taper spindle to accept MT5 tooling holders, or extending reach to accommodate deeper workpiece setups. It is suited for stationary machine tools running standard Morse taper tooling in both light production and job shop settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMT5 inside taper accepts standard MT5 shanks and tooling\u003c\/li\u003e\n  \u003cli\u003eMT4 outside taper seats directly into MT4 spindles or holders\u003c\/li\u003e\n  \u003cli\u003e11-7\/8 inch overall length provides extended reach for deep setups\u003c\/li\u003e\n  \u003cli\u003eMedium carbon steel construction for durability under machine tool loads\u003c\/li\u003e\n  \u003cli\u003eSoft body with hardened tang resists drive-point wear and tang fracture\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or tooling-room addition for machine tools equipped with MT4 spindle bores requiring MT5 inside taper tooling adaptation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or machine tool technicians. Power down and lock out the machine spindle before seating or removing any taper adapter. Ensure both the spindle bore and the adapter taper surfaces are clean and free of chips or burrs before insertion, as debris will prevent full taper contact and cause runout. Remove the adapter with a proper drift through the spindle drift slot rather than striking the tooling directly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Taper Size\u003c\/strong\u003e: MT5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Taper Size\u003c\/strong\u003e: MT4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdapter Type\u003c\/strong\u003e: Morse Taper to Morse Taper Extension\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 11-7\/8 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\u003c\/strong\u003e: Soft with Hardened Tang\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7.25 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: SC00186544\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691803410738,"sku":"SC00186544","price":76.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bac9bab9fbdef6add7fbf33893db4fd1.jpg?v=1788289930","url":"https:\/\/voomisupply.com\/products\/value-collection-sc00186544-mt5-to-mt4-taper-extension-adapter","provider":"Voomi Supply","version":"1.0","type":"link"}
