Built with a high-speed steel body and a 3-flat shank, this bit transfers torque efficiently while resisting slippage in the chuck. The cutting tip uses a percussion geometry to fracture and clear masonry material with each hammer stroke. At 7\/16 inch in diameter with a 4-inch flute length and 6-inch overall length, it handles common anchor hole and through-hole drilling tasks on structural and finish masonry surfaces. Licensed contractors and masonry tradespeople rely on this geometry for consistent, repeatable results in rotary hammer applications.\u003c\/p\u003e\u003cp\u003eThis bit is suited for residential and light commercial masonry work where anchor setting, conduit penetrations, or fastener holes are required. Typical applications include drilling into poured concrete walls, CMU block, and brick veneer. The 2-flute design provides adequate chip clearance in standard-depth holes. The 3-flat shank seats securely in SDS-compatible and keyed hammer drill chucks equipped to accept that profile, making it a practical carry item for field work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCarbide-tipped percussion cutting tip for masonry, concrete, block, and brick\u003c\/li\u003e\n\u003cli\u003e3-flat shank design resists bit rotation and slippage in the chuck\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel flute body for durability under repeated hammer loads\u003c\/li\u003e\n\u003cli\u003e7\/16 inch cutting diameter suits common anchor and fastener hole sizes\u003c\/li\u003e\n\u003cli\u003e4-inch flute length with 6-inch overall length for standard masonry depth requirements\u003c\/li\u003e\n\u003cli\u003e2-flute configuration promotes debris evacuation during drilling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement-grade rotary hammer drill bit for use with rotary hammer tools and hammer drills accepting a 3-flat, 1\/4 inch shank.

Always confirm the drill chuck is fully seated and locked onto the 3-flat shank before applying power. Wear appropriate eye protection and respiratory protection when drilling masonry. Follow OSHA and jobsite-specific silica dust control requirements when drilling concrete or masonry materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: 3-Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Carbide Tipped, High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Shape\u003c\/strong\u003e: Percussion\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Block, Brick, Concrete\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 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: 48-20-9125\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MILWAUKEE","offers":[{"title":"Default Title","offer_id":51714552660274,"sku":"48-20-9125","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/348166ed44e62a87140b82591008aaf4.jpg?v=1788503116","url":"https:\/\/voomisupply.com\/products\/milwaukee-tool-48-20-9125-hammer-drill-bit-7-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
