Sized at 1\/4 inches diameter with a 4-inch overall length and 2-inch working length, this bit features a variable flute geometry engineered for maximum debris extraction. The breaker point pulverizes material at the bore face for faster penetration, while enhanced rebar guards increase durability when drilling through hard aggregate and rebar. A reinforced flute reduces vibration and extends service life across demanding job site conditions. Licensed electricians, plumbers, and general contractors regularly rely on this bit class for anchor and sleeve installations in concrete substrates.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for residential and commercial concrete drilling tasks where anchor placement, conduit penetration, or fixture attachment requires precise, repeatable holes. The centering tip allows exact spot drilling without bit walk on hard surfaces. A wear mark indicator signals when the bit diameter no longer meets ANSI tolerance requirements, helping tradespeople maintain code-compliant hole sizing. The variable flute design is particularly effective in cordless rotary hammer platforms where battery efficiency directly affects productivity, delivering consistent performance in standard concrete.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-cutter SDS Plus shank fits standard SDS Plus rotary hammers\u003c\/li\u003e\n  \u003cli\u003eVariable flute geometry maximizes debris extraction and drilling speed\u003c\/li\u003e\n  \u003cli\u003eEnhanced rebar guards for durability in hard aggregate and rebar conditions\u003c\/li\u003e\n  \u003cli\u003eBreaker point tip pulverizes material for faster penetration rates\u003c\/li\u003e\n  \u003cli\u003eCentering tip enables exact spot drilling on hard concrete surfaces\u003c\/li\u003e\n  \u003cli\u003eWear mark indicator shows when bit no longer meets ANSI diameter requirements\u003c\/li\u003e\n  \u003cli\u003eReinforced flute reduces vibration and extends overall bit life\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with SDS Plus rotary hammers in corded and cordless configurations for general concrete drilling applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of this bit type is performed by licensed tradespeople or experienced contractors working with SDS Plus rotary hammers. Confirm the tool chuck is fully seated and locked before operation. Wear appropriate eye protection and dust control measures when drilling concrete, as required by OSHA standards. Inspect the bit for the wear mark indicator before each use to verify the diameter meets ANSI requirements for the intended application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: SDS Plus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Configuration\u003c\/strong\u003e: 2-cutter\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBit Diameter\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWorking 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\u003eApplication\u003c\/strong\u003e: General concrete, hard aggregate, rebar conditions\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 045242111626\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 48-20-7430\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MILWAUKEE","offers":[{"title":"Default Title","offer_id":51383699505458,"sku":"48-20-7430","price":28.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312671127.png?v=1782604817","url":"https:\/\/voomisupply.com\/products\/milwaukee-48-20-7430-sds-plus-drill-bit-1-4-in-x-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
