Built on a spline shank with a 3\/4 inch shank size, it delivers an overall length of 22 inches and a cutting depth of 3 inches. The one-piece construction maximizes energy transfer from the hammer to the cutting edge, while the thick-wall core body holds up under the stress of large rotary hammer operation. A fluted exterior reduces friction and clears debris from the kerf efficiently. Licensed contractors and experienced masonry trades are the primary installers of this bit.\u003c\/p\u003e\n\u003cp\u003eThis core bit is suited for residential and commercial masonry applications requiring clean, large-diameter through-holes or shallow blind holes in block, brick, or concrete. The asymmetric tooth pitch with alternating tooth geometries accelerates material pulverization for faster cutting cycles. It is available in spline shank configuration and is intended for use in compatible spline-drive rotary hammers. Note that the centering bit 48-20-5495 is recommended for accurate hole placement but is not included. Use drift key 48-20-5497 to remove the centering bit from the core bit after use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-piece design maximizes energy transfer and reduces component wear during heavy hammering\u003c\/li\u003e\n  \u003cli\u003eCarbide cutting edge for durable performance in masonry and concrete applications\u003c\/li\u003e\n  \u003cli\u003eAsymmetric tooth pitch with alternating geometries increases material pulverization rate\u003c\/li\u003e\n  \u003cli\u003eFluted core exterior minimizes friction and speeds debris removal from the kerf\u003c\/li\u003e\n  \u003cli\u003eThick-wall core body withstands the demands of large-frame rotary hammers\u003c\/li\u003e\n  \u003cli\u003eSpline shank provides secure, torque-efficient connection to compatible rotary hammers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with spline-drive rotary hammers.

Power down and disconnect the rotary hammer from its power source before attaching or removing the bit. The core bit cuts a kerf only — the inside core slug must be manually removed by the operator before drilling can continue to greater depth. Follow the rotary hammer manufacturer guidelines and applicable jobsite safety codes when operating large SDS or spline drive equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: 1-Piece\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Spline\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 22 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Depth\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Silver\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: 48-20-5488\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MILWAUKEE","offers":[{"title":"Default Title","offer_id":51138834694450,"sku":"48-20-5488","price":364.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305532823.jpg?v=1778264408","url":"https:\/\/voomisupply.com\/products\/milwaukee-48-20-5488-1-piece-carbide-spline-core-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
