At 14 inches overall length (OAL), this adapter extends reach for deep-bore drilling, reaming, or similar metal-cutting operations where standard tooling cannot access the workpiece. Constructed from medium carbon steel with a soft body and hardened tang, it provides the toughness needed for sustained cutting loads while maintaining tang integrity under drive force. Machinists and tool-and-die technicians are the primary users of this type of adapter.\u003c\/p\u003e\n\u003cp\u003eThis adapter is suited for use in heavy-duty machining centers, floor-standing drill presses, and horizontal or vertical milling machines equipped with an MT6 spindle taper. The MT4 inside socket accepts standard MT4-shanked tooling such as drill chucks, twist drills, reamers, and boring tools. The extended OAL makes it particularly useful for production setups involving deep-hole work or fixtures that require additional clearance between the spindle face and the workpiece or tooling assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMT4 inside taper accepts standard MT4-shank tooling\u003c\/li\u003e\n  \u003cli\u003eMT6 outside taper fits MT6 machine spindles\u003c\/li\u003e\n  \u003cli\u003e14-inch OAL provides extended reach for deep-bore applications\u003c\/li\u003e\n  \u003cli\u003eMedium carbon steel construction for rigidity under cutting loads\u003c\/li\u003e\n  \u003cli\u003eSoft body with hardened tang resists drive-force wear at the spindle interface\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit extension adapter for machine spindles with an MT6 taper, accepting any MT4-shank tooling per standard Morse taper specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Before inserting or removing the adapter, power down the machine and bring the spindle to a complete stop. Clean both the spindle bore and the adapter taper surfaces thoroughly to remove chips, oil film, or debris that could cause misalignment or reduce holding force. Use a drift punch and the appropriate spindle slot to release the adapter during removal; do not strike the adapter body 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: MT4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Taper Size\u003c\/strong\u003e: MT6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 14 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: 13 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: SC00186460\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720858206514,"sku":"SC00186460","price":90.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bd0f2078b17765c7a8f3713c09f8139a.jpg?v=1788570059","url":"https:\/\/voomisupply.com\/products\/value-collection-sc00186460-mt4-to-mt6-taper-extension","provider":"Voomi Supply","version":"1.0","type":"link"}
