The adapter accepts an MT4 inside taper and presents an MT3 outside taper, allowing technicians to seat MT3-shank tooling deeper in a machine spindle without modifying the machine. Overall length is 9.5 inches. The body is medium carbon steel, hardened and ground throughout, providing consistent taper geometry and surface finish for reliable tool seating and accurate concentricity under cutting loads.\u003c\/p\u003e\n\u003cp\u003eThis adapter is suited for drilling, boring, and reaming applications on drill presses, milling machines, and lathes equipped with MT3 spindle receivers. It is a practical solution when standard tool length is insufficient for deep-hole work or when fixture geometry requires additional clearance between the spindle face and the workpiece. Machinists and toolroom technicians are the primary installers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMT4 inside taper accepts MT4-shank tooling or arbors\u003c\/li\u003e\n  \u003cli\u003eMT3 outside taper seats into any standard MT3 spindle receiver\u003c\/li\u003e\n  \u003cli\u003e9.5-inch overall length extends tool reach for deep-hole and clearance applications\u003c\/li\u003e\n  \u003cli\u003eMedium carbon steel construction hardened and ground throughout for precision fit and durability\u003c\/li\u003e\n  \u003cli\u003eConsistent taper geometry supports accurate tool alignment and minimal runout\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with MT3 spindle machines and MT4-shank tooling.

Clean both the spindle bore and the adapter taper with a lint-free cloth to remove chips, oil, and grit before seating — contamination on the taper surfaces will cause misalignment and runout. Drive the adapter firmly into the spindle using a rubber or dead-blow mallet; never use a steel hammer directly on the taper. Remove the adapter with a taper drift inserted through the spindle drift slot to avoid damage to the taper surfaces.\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 Extension\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: MT3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 9.5 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\u003c\/strong\u003e: Hardened and Ground Throughout\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.6 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: SC00187435\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693556334898,"sku":"SC00187435","price":69.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8602d809e3ac2fc20f711c2e175f666e.jpg?v=1788314049","url":"https:\/\/voomisupply.com\/products\/value-collection-sc00187435-mt4-to-mt3-morse-taper-extension","provider":"Voomi Supply","version":"1.0","type":"link"}
