The shank features a 3\/4-inch (0.75 inches) straight stepped shank profile with a T12 neck thread and a neck diameter of 0.72 inches. Overall length is 5.0 inches, with a projection of 1.0 inch and a head length of 0.88 inches. Constructed from steel, this shank is intended for licensed machinists and tooling specialists setting up modular milling operations on CNC machining centers and manual mills. It accepts a wide range of Multimaster exchangeable milling tips, allowing rapid tip changeover without removing the shank from the spindle.\u003c\/p\u003e\u003cp\u003eThis shank is suited for milling applications in both production shop and job-shop environments. The Multimaster platform is commonly used in face milling, shoulder milling, slotting, and profiling operations on machining centers. The stepped shank geometry is appropriate for standard toolholder collets and milling chucks designed around 3\/4-inch bore sizes. No coolant-through capability is present on this unit, making it best suited for flood or external coolant delivery setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eT12 neck thread interfaces with the full range of Multimaster exchangeable milling tips\u003c\/li\u003e\n\u003cli\u003e3\/4-inch stepped straight shank fits standard milling chucks and collet holders\u003c\/li\u003e\n\u003cli\u003e0.72-inch neck diameter with 1.0-inch effective length for reach into workpiece features\u003c\/li\u003e\n\u003cli\u003e5.0-inch overall length suitable for standard spindle-to-work clearance setups\u003c\/li\u003e\n\u003cli\u003eSteel construction for rigidity and durability under milling loads\u003c\/li\u003e\n\u003cli\u003eNo Weldon flat and no coolant-through — external coolant delivery required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible milling tip styles include: MM EA, MM EA-CF, MM EB, MM EBA, MM EC-10, MM EC-3, MM EC-4, MM EC-6, MM EC-8, MM EC-CF, MM EC-D, MM EC-H, MM ECD, MM ECF, MM ECS, MM ECU, MM EDF, MM EFF, MM EFS, MM EFS-CF, MM EPG, MM ERA, MM ERS, MM ETR, MM FF, MM GRIT-16K\/P, MM GRIT-18K\/P, and MM GRIT-22K\/P.

Before mounting or removing any milling shank, ensure the machine spindle is fully stopped and the control is in an E-stop or locked-out state per applicable lockout\/tagout (LOTO) procedures. Torque the exchangeable tip to the manufacturer specification using the appropriate Multimaster assembly key. Inspect the T12 thread interface and seating surfaces for chips or damage before each tip change to maintain runout accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Multimaster\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: MM S-A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Stepped Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches (3\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Thread Size\u003c\/strong\u003e: T12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.72 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 0.72 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Diameter\u003c\/strong\u003e: 0.72 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 1.0 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEffective Length\u003c\/strong\u003e: 1.0 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 0.88 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Milling\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeldon Flat\u003c\/strong\u003e: No\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: 0.5 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3103852\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51750224167218,"sku":"3103852","price":219.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a9032f80978051d4795759f6adfbf3ff.jpg?v=1788914395","url":"https:\/\/voomisupply.com\/products\/iscar-3103852-milling-shank-3-4-inch-stepped-multimaster","provider":"Voomi Supply","version":"1.0","type":"link"}
