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 2 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 7 x 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 3 x faster than current methods resulting in up to 66% labor savings. Epoxy and anchor placement can now be accomplished immediately.
