Built on a high-speed steel body with a 3\/16-inch cutting diameter, this bit features a three-flat shank that locks securely into compatible rotary hammer chucks to prevent slipping under load. The 2-inch flute length clears debris efficiently during drilling, and the overall length of 4 inches gives the user adequate reach for most standard masonry penetrations. Weighing approximately 0.03 pounds, it is a compact single-piece tool suited for licensed electricians, plumbers, and HVAC technicians who need to core through concrete, block, or brick during rough-in work.\u003c\/p\u003e\n\u003cp\u003eThis bit is intended for use in residential and light commercial applications where hammer drill penetration through block, brick, or concrete is required. Typical install scenarios include anchoring mechanical equipment, routing conduit or pipe through masonry walls, and setting fasteners in concrete substrates. The percussion cutting shape is optimized for rotary hammer operation rather than standard drill-only mode, making it appropriate for use with corded or cordless SDS-type or three-flat chuck hammer drills.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbide-tipped percussion cutting shape rated for block, brick, and concrete\u003c\/li\u003e\n  \u003cli\u003eThree-flat shank design resists rotation and slippage in the chuck\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch cutting diameter with a 1\/4-inch shank diameter\u003c\/li\u003e\n  \u003cli\u003e2-inch flute length for efficient debris evacuation during hammer drilling\u003c\/li\u003e\n  \u003cli\u003e4-inch overall length suits standard masonry penetration tasks\u003c\/li\u003e\n  \u003cli\u003eLightweight single-piece construction at 0.03 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement bit for use with rotary hammer drills accepting a three-flat chuck configuration and 1\/4-inch shank diameter tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified tradesperson familiar with hammer drill operation and applicable local codes. Always power down and unplug or battery-disconnect the tool before inserting or removing the bit. Confirm the chuck is fully tightened and the bit is seated securely before applying percussion force. Eye protection and appropriate dust controls are required when drilling into concrete or masonry per standard jobsite safety practices.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Three Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flats\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Shape\u003c\/strong\u003e: Percussion\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Block, Brick, Concrete\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: MILWAUKEE TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 48-20-9105\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MILWAUKEE","offers":[{"title":"Default Title","offer_id":51709279207730,"sku":"48-20-9105","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a60c2696d556d5c0e74834c82691c142.jpg?v=1788453889","url":"https:\/\/voomisupply.com\/products\/milwaukee-tool-48-20-9105-hammer-drill-bit-3-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
