Diablo's AMPED™ Rebar Demon™ 4-Cutter Full Carbide Head Dust Extraction Hammer Drill Bits amplify concrete drilling with the only hammer drill bits to drill fast, clean holes into clean and reinforced in two easy steps. The AMPED™ Rebar Demon™ bits feature Diablo's highly durable Dura-Carbide to withstand up to 1800°F of intense heat whereas standard bits fail at 800°F. Diablo's impact resistant 4-cutter tungsten 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 in extreme impact situations. The steel sleeve along with the Snap-Lock™ Adapter (sold separately) creates the first ever 4-cutter full carbide head two-step clean hole dust extraction system that removes up to 97% of dust and debris. The design of this bit along with its dust cap captures all small particles (surface debris) throughout the drilling process, reducing dust exposure to a maximum. The elimination of the "Blow-Brush-Blow" cleaning method and the need of rebar cutters is now obsolete, making hole preparation up to 3X faster than current methods resulting in up to 66% labor savings. Epoxy and anchor placement can now be accomplished immediately. In addition, reduction of airborne silica dust helps to create a safer and healthier working environment, whether it be indoors or outdoors. Including a Precision Tip, the sharp 90° pyramid shaped tip delivers the stability and accuracy required to produce fast, precise holes in reinforced concrete for anchor setting. A visible wear mark indicates and assures the accuracy of the drilling diameter. Whether completing interior, overhead drilling or exterior jobs, these revolutionary dust extraction hammer drill bits deliver ultra-clean, dust free holes and working environments, maximum speed, and extreme durability.
