The shank accepts a 3\/8-16 drawbar thread for secure retention in the spindle and features a 7\/8-20 threaded mount for attachment to compatible boring heads. Weighing 1 pound, this shank provides a rigid, concentric interface between the machine spindle and the boring head body. It does not include coolant-through capability. Machinists and tool-and-die professionals rely on this type of shank for precise boring operations on knee mills and similar MT2-spindle machines.\u003c\/p\u003e\u003cp\u003eThis taper shank is suited for manual milling machines equipped with an MT2 spindle taper, commonly found in knee mills, drill presses converted for light boring, and small vertical machining centers with MT2 tooling compatibility. The 7\/8-20 threaded mount is a standard interface for mid-size boring heads used in general-purpose metalworking and maintenance machining environments. Installation is straightforward, making it a practical replacement or spare shank for shops running MT2 tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMT2 taper shank for direct spindle mounting in MT2-equipped machines\u003c\/li\u003e\n\u003cli\u003e7\/8-20 threaded mount connects to compatible boring heads\u003c\/li\u003e\n\u003cli\u003e3\/8-16 drawbar thread for positive spindle retention\u003c\/li\u003e\n\u003cli\u003eNo coolant-through passages, keeping the design simple and durable\u003c\/li\u003e\n\u003cli\u003eCompact 1-pound construction for reduced spindle load\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or spare taper shank for boring heads with a 7\/8-20 threaded connection, used in milling machines with an MT2 spindle taper.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom professional. Power down and lock out the milling machine before inserting or removing the shank from the spindle. Clean the spindle taper and shank taper thoroughly before seating to ensure full contact and runout accuracy. Secure the shank using the drawbar with appropriate torque per the machine manufacturer guidelines, and never run the machine without the drawbar engaged.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Size\u003c\/strong\u003e: MT2 (Morse Taper 2)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreaded Mount Size\u003c\/strong\u003e: 7\/8-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrawbar Thread Size\u003c\/strong\u003e: 3\/8-16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 220-1521\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689757016370,"sku":"220-1521","price":61.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c45c3a3d72d03c0b33270eef4d64603c.jpg?v=1788263920","url":"https:\/\/voomisupply.com\/products\/value-collection-220-1521-boring-head-taper-shank-mt2","provider":"Voomi Supply","version":"1.0","type":"link"}
