About this item

  • 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.

This masonry bit works well. It fit and locked securely into my DeWalt hammer drill. It spins like it should and bores into 4000 psi reinforced concrete smoothly.

It worked better than we were expecting! We have used other concrete bits and this was the best so far!

Works extremely well, and didn't bend as easily as some other long bits I've used. Stashes this in the same case as several Bosch and even cheap Chinese bits for about a month. This was rusty the whole way up and down the flutes. Nothing else was.

Works very well , will drill through concrete brick without a hammering drill without any problems.
