Designed for concrete, masonry, and similar hard-material drilling applications, this bit features enhanced rebar guards for increased durability and reinforced flutes engineered to minimize vibration during operation. Breaker points accelerate penetration rates, and a variable flute geometry delivers up to 20 percent more holes per charge when used with cordless rotary hammers. A centering tip allows precise spot placement without walking, and wear mark indicators signal end-of-service life when the bit no longer meets ANSI requirements. Licensed HVAC techs, plumbers, electricians, and general trade professionals rely on this bit for anchor, conduit, and rough-in drilling in concrete and block substrates.\u003c\/p\u003e\u003cp\u003eThe 48-20-7471 is suited for both residential and commercial jobsite applications wherever SDS Plus rotary hammers are the tool of choice. Common use cases include drilling anchor-bolt holes in foundation walls, penetrating concrete floors and block for conduit runs, and rough-in work in poured and precast concrete. The SDS Plus shank is compatible with the broad range of SDS Plus chuck rotary hammers used across the electrical, mechanical, and plumbing trades. Its cordless-optimized variable flute design makes it particularly effective with battery-powered rotary hammers where charge conservation is a priority on extended runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVariable flute geometry delivers up to 20 percent more holes per battery charge in cordless rotary hammers\u003c\/li\u003e\n\u003cli\u003eEnhanced rebar guards increase durability when drilling into rebar-reinforced concrete\u003c\/li\u003e\n\u003cli\u003eBreaker points lead to faster drilling speeds and improved penetration rates\u003c\/li\u003e\n\u003cli\u003eCentering tip enables exact spot drilling and prevents bit walking on hard surfaces\u003c\/li\u003e\n\u003cli\u003eWear mark indicators show end-of-life when bit no longer meets ANSI specification\u003c\/li\u003e\n\u003cli\u003eReinforced flutes minimize vibration for improved control and maximum tool-side durability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with SDS Plus chuck rotary hammers used in concrete, masonry, and block drilling applications across the electrical, mechanical, and plumbing trades.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this bit requires an SDS Plus rotary hammer; confirm chuck type before installing. Always de-energize and lock out any electrical systems before drilling near conduit or service panels, and shut off water supply before penetrating walls containing plumbing. Eye protection, hearing protection, and dust control measures are required when drilling concrete or masonry per standard jobsite safety practices. Inspect wear mark indicators before each use and retire the bit when indicators confirm the ANSI wear threshold has been reached.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eDiameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorking 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\u003eWeight\u003c\/strong\u003e: 30 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 125\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 Electric Tool Corp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 48-20-7471\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MILWAUKEE","offers":[{"title":"Default Title","offer_id":51525388304690,"sku":"48-20-7471","price":906.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/077acc45c098ddb3c0c40e18f2626ad0_bcbb0793-bd70-4846-88cf-7d371c7e275a.jpg?v=1785472455","url":"https:\/\/voomisupply.com\/products\/milwaukee-48-20-7471-sds-plus-2-cutter-bit-1-2x4x6","provider":"Voomi Supply","version":"1.0","type":"link"}
