Milwaukee MX4 4-Cutter SDS-Plus Rotary Hammer Drill Bits provide up to 4X Life in Rebar and up to 20 percentage more holes per charge in cordless rotary hammers. The enhanced rebar guards and 4-Cutter more→90 deg. head design provide increased life and durability in hard aggregate and rebar. The variable flute allows for maximum debris extraction, while making it a very durable bit in corded and cordless rotary hammers. The increased life and efficiency of the MX4 4-Cutter drill bit line provides the ideal solution in general concrete and reinforced concrete for cordless and corded rotary hammer users.

Milwaukee Thunderbolt pilot bits are designed for extreme durability and long life. The Thunderbolt web features a thicker core than a standard pilot bit, which provides ultimate strength and protects more→against side-load breakage. A specially designed parabolic flute form clears chips and debris fast to keep the bit cool. A precision start, 135 deg. split point tip starts on contact to keep the bit from walking for fast, accurate holes. Excellent for drilling on curved surfaces, requires less effort to drill and is highly recommended for use with portable drills.

Diablo's revolutionary, most complete range of SDS-Plus and SDS-Max Rebar Demo 4-cutter full-carbide head hammer drill bits are the only bits designed to be the most durable, fastest and coolest solut more→ions on the market. The Rebar Demon bits feature up to 2X more Dura-Carbide to withstand up to 1800-degrees of intense heat whereas standard bits fail at 800-degrees. Diablo's impact resistant 4-cutter full-carbide head withstands the stress of high-powered hammer drills and the impact of rebar by taking small bites of rebar to deliver controlled carbide wear, reduced vibration and up to 7X longer life. Produced with Tri-Metal Fusion Welding, the full-carbide head resists heat and prevents breakage …
