It features a 3\/4-inch cutting diameter paired with a 1\/2-inch Weldon shank, allowing it to run in standard 1\/2-inch chucks without requiring a full-size chuck upgrade. The 135-degree split point provides fast, self-centering penetration with reduced walking on entry. Constructed from high speed steel with a coated finish, this bit handles the friction and heat generated during extended drilling cycles in metal, wood, and composite materials.\u003c\/p\u003e\u003cp\u003eThis bit is sized for applications where a full 3\/4-inch shank would be impractical — particularly when using 1\/2-inch drill motors or magnetic drill press chucks common on commercial and industrial jobsites. The 3-flat Weldon shank design prevents bit slippage in the chuck under high-torque conditions. With a 3-inch flute length and 6-inch overall length, it provides adequate reach for typical through-hole and blind-hole work in structural components, framing hardware, and mechanical systems. Licensed electricians, plumbers, HVAC mechanics, and general contractors are the primary installers of this tool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4-inch cutting diameter on a 1\/2-inch reduced Weldon shank — runs in standard 1\/2-inch chucks\u003c\/li\u003e\n\u003cli\u003e135-degree split point for self-centering entry and reduced thrust force\u003c\/li\u003e\n\u003cli\u003e3-flat Weldon shank prevents rotation and slippage under high torque\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with coated finish for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003e3-inch flute length supports up to 3 inches of drilling depth\u003c\/li\u003e\n\u003cli\u003e6-inch overall length for reach in confined or layered material applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 1\/2-inch keyed or keyless drill chucks and compatible magnetic drill press arbors that accept Weldon-shank bits.

Secure the Weldon shank firmly in the chuck, ensuring at least one flat engages the chuck set screw when used in a magnetic drill press. Wear appropriate eye protection during drilling operations. Inspect the cutting edges before each use and replace if chipping or significant wear is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 3\/4 inch (0.7500 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flats\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Reduced Shank\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Jobsite Drilling\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.42 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MILWAUKEE TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 48-89-4640\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MILWAUKEE","offers":[{"title":"Default Title","offer_id":51699873022258,"sku":"48-89-4640","price":51.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/49f67e28de609af55a9d5bfa4a0fa5eb.jpg?v=1788382389","url":"https:\/\/voomisupply.com\/products\/milwaukee-tool-48-89-4640-reduced-shank-drill-bit-3-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
