Key Features & Design

• Up to 7X longer life versus standard 2-cutter hammer drill bits.
• Diablo made Dura-Carbide™ features up to 2X more carbide that withstands up to 1800°F of intense heat to combat rebar hits versus standard bits that fail at 800°F.
• Impact Resistant 4-Cutter Full Carbide Head extracts smaller bites of rebar for controlled, consistent carbide wear and reduced vibration to deliver fast, precise holes.
• Tri-Metal Fusion Welding features up to 3X stronger weld to keep the full carbide head intact during extreme impact such as rebar.
• Precision Tip delivers the stability and accuracy required to produce fast, precise holes.
• Application: Reinforced concrete and concrete.
