Our MILWAUKEE 3-1/8" X 22" SDS Max Tunnel Bits are ideal for drilling deep, large holes in concrete, concrete with rebar, brick, and block. The high volume sloped flutes and 22" long shaft allow for continuous deep hole drilling and faster dust removal avoiding the need to clear out a core. Our concrete drill bits feature a robust head equipped with a 3-cutter design and sharp carbide centering tip for precise starts and fast grinding of concrete and rebar. The carbide teeth are engineered with rebar chamfers to quickly shear through the embedded rebar while maintaining maximum durability and preventing tooth breaks. For use in SDS Max Rotary Hammers.

The Milwaukee SDS-Plus 4-Cutter MX4 1/4 -inch X 10 -inch X 12 -inch Drill Bits feature solid carbide heads that deliver up to 5x longer life in concrete with rebar. Engineered with rebar guards to provide maximum durability in hard aggregate and rebar. MX4 4-Cutter bits are designed with sharp centering tips for exact spot drilling in concrete and metal decking. The 4-cutter design prevents lock-up in rebar, reducing downtime. Variable flutes remove dust faster, reducing heat and delivering up to 20% more holes per battery charge. Wear mark indicator shows users the end of life when the bits no longer meet the ANSI requirement. The Milwaukee MX4 4-Cutter Drill Bits are ideal for concrete with rebar and masonry applications.

Milwaukees one piece carbide tipped core bits are ideal for drilling large holes in brick, block, and concrete. The asymmetric tooth pitch with alternating tooth geometries for up to 20% faster drilling speeds. The one piece design maximizes energy transfer and the thick wall core body is durable in large hammers. The fluted core exterior minimizes friction loss and removes debris faster. Core bit cut with the outer cutting edge only. The inside core must be removed to allow for deeper hole drilling applications beyond 3-inch. Centering bit 48-20-5495 (included) is recommended for exact spot drilling and to avoid bit wandering during use. The drift key 48-20-5497 (not included) allows for easy removal of the centering bit. The one piece core bits are available in SDS-Max or Spline shanks, ranging from 1-1/2-inch to 6-inch diameters and overall lengths of 11-3/8-inch or 22-inch, with a drilling depth of 3-inch.

Diablos SDS-Max Bushing Tools deliver extreme durability and stability when roughing up concrete to create a desired exterior finish. A unique heat treatment process strengthens the steel body to withstand the stress of high-powered hammer drills and the impact of hitting concrete. Optimized for maximum performance in corded and cordless SDS-Max rotary hammers.
