Diablos 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 in extreme impact situations. Precision Tip delivers the stability and accuracy required to produce fast, precise holes in reinforced concrete for anchor setting.
