Diablo Rebar Demon SDS-Max 4-Cutter Carbide-Tipped Hammer Drill Bit – 1-3/4″ Diameter, 21″ Length, 16″ Working Length – DMAMX1390
Most Durable – 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.
Longer Life – Up to 7X longer life versus standard 2-cutter hammer drill bits. Tri-Metal Fusion Welding features up to 3X stronger weld to keep the full carbide head intact during extreme impact such as rebar.
Precise and Stability – Precision tip delivers stability and accuracy required for fast, precise holes. Optimized flute design removes dust faster, keeping the carbide head cooler for ultimate strength and durability.
Impact Resistant – With 4-Cutter smaller bits of rebar for controlled, consistent carbide wear and reduced vibration delivering fast, precise holes and longer life.
Superior Performance – Optimized for maximum performance in corded and cordless SDS Plus or SDS Max rotary hammers and wear mark indicator ensures precise hole making.
