By utilizing a one-piece 22-inch shaft and a specialized 3-cutter carbide head, this bit bridges the gap between standard rotary hammer bits and core bits. The mechanical advantage lies in the high-volume sloped flutes, which facilitate rapid dust evacuation, maintaining high drilling speeds even at maximum depth. For the professional contractor, this translates to a lower cost-per-hole and reduced strain on the SDS Max rotary hammer’s motor by minimizing friction and heat buildup during extended runs through rebar-reinforced concrete.\u003c\/p\u003e\u003cul style=\"list-style: none; padding: 0; margin: 0 0 18px 0;\"\u003e\n\u003cli style=\"margin-bottom: 8px; font-size: 15px; display: flex; align-items: flex-start; font-family: sans-serif; color: #333333;\"\u003e\n\u003cspan style=\"color: #E31E24; font-weight: 900; margin-right: 8px; font-style: italic;\"\u003e\/\u003c\/span\u003e 3-Cutter Carbide Centering Tip provides surgical precision during starts while effectively grinding through high-PSI concrete and embedded rebar.\u003c\/li\u003e\n\u003cli style=\"margin-bottom: 8px; font-size: 15px; display: flex; align-items: flex-start; font-family: sans-serif; color: #333333;\"\u003e\n\u003cspan style=\"color: #E31E24; font-weight: 900; margin-right: 8px; font-style: italic;\"\u003e\/\u003c\/span\u003e Rebar Chamfers engineered into the carbide teeth prevent catastrophic tooth failure when encountering structural steel.\u003c\/li\u003e\n\u003cli style=\"margin-bottom: 8px; font-size: 15px; display: flex; align-items: flex-start; font-family: sans-serif; color: #333333;\"\u003e\n\u003cspan style=\"color: #E31E24; font-weight: 900; margin-right: 8px; font-style: italic;\"\u003e\/\u003c\/span\u003e High-Volume Sloped Flutes ensure continuous material removal, eliminating the need for the repetitive \"peck drilling\" cycles required to clear debris.\u003c\/li\u003e\n\u003cli style=\"margin-bottom: 8px; font-size: 15px; display: flex; align-items: flex-start; font-family: sans-serif; color: #333333;\"\u003e\n\u003cspan style=\"color: #E31E24; font-weight: 900; margin-right: 8px; font-style: italic;\"\u003e\/\u003c\/span\u003e One-Piece 22\" Shaft Design optimizes energy transfer from the rotary hammer directly to the cutting head for maximum impact force.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdetails style=\"border: 2px solid #000; margin-bottom: 25px; background: #fafafa; font-family: sans-serif;\"\u003e\u003csummary style=\"background: #FCEE21; color: #000; padding: 12px 15px; font-weight: 900; cursor: pointer; text-transform: uppercase; border-bottom: 2px solid #000; font-style: italic; outline: none;\"\u003eTECHNICAL SPECIFICATIONS\u003c\/summary\u003e\u003cdiv style=\"padding: 15px; color: #000000;\"\u003e\u003ctable style=\"width: 100%; border-collapse: collapse; color: #000000; font-size: 14px;\"\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px; border-bottom: 1px solid #ddd; font-weight: bold; color: #000000;\"\u003eDiameter\u003c\/td\u003e\n\u003ctd style=\"padding: 8px; border-bottom: 1px solid #ddd; color: #000000;\"\u003e3-1\/8\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px; border-bottom: 1px solid #ddd; font-weight: bold; color: #000000;\"\u003eOverall Length\u003c\/td\u003e\n\u003ctd style=\"padding: 8px; border-bottom: 1px solid #ddd; color: #000000;\"\u003e22\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px; border-bottom: 1px solid #ddd; font-weight: bold; color: #000000;\"\u003eShank Type\u003c\/td\u003e\n\u003ctd style=\"padding: 8px; border-bottom: 1px solid #ddd; color: #000000;\"\u003eSDS Max\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px; border-bottom: 1px solid #ddd; font-weight: bold; color: #000000;\"\u003eCutter Style\u003c\/td\u003e\n\u003ctd style=\"padding: 8px; border-bottom: 1px solid #ddd; color: #000000;\"\u003e3-Cutter Carbide\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px; border-bottom: 1px solid #ddd; font-weight: bold; color: #000000;\"\u003eMaterial Application\u003c\/td\u003e\n\u003ctd style=\"padding: 8px; border-bottom: 1px solid #ddd; color: #000000;\"\u003eConcrete, Rebar, Brick, Block\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003c\/div\u003e\u003c\/details\u003e\u003ch4 style=\"color: #E31E24; text-transform: uppercase; font-weight: 900; border-bottom: 3px solid #FCEE21; padding-bottom: 4px; margin-top: 25px; font-size: 18px; font-family: sans-serif; font-style: italic;\"\u003eWHAT'S IN THE BOX\u003c\/h4\u003e\u003cp style=\"font-size: 15px; color: #333333; font-family: sans-serif;\"\u003e(1) 3-1\/8\" X 22\" One Piece SDS Max Tunnel Bit (48-20-5324)\u003c\/p\u003e","brand":"Milwaukee Tool","offers":[{"title":"Default Title","offer_id":46358776021177,"sku":"48205324","price":389.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0565\/7529\/5673\/files\/48-20-5324_Primary_b4001ac1-8c75-4352-8512-1835c8be8c29.jpg?v=1770754570","url":"https:\/\/thepowertoolstore.com\/products\/milwaukee-3-1-8-x-22-sds-max-tunnel-bit-sds-max-48-20-5324","provider":"The Power Tool Store","version":"1.0","type":"link"}
