SDS Drill Bit That Doesn't Care What's In The Way
You're mid-job, drilling a hole through reinforced concrete. Maybe it's a sewer drain, maybe it's a footing, and you feel it. That dead stop. Your bit just found rebar, and it's not going any further.
If you've been drilling with a standard SDS bit for rebar, you know what comes next: pull the bit, reposition, and drill a whole new hole somewhere the rebar isn't. Except now you've got an extra hole in your concrete, extra time on the clock, and a bit that may already be toast. Bad Dog's 12" SDS bit was built to skip that whole problem. It drills straight through rebar instead of stopping at it.
Why Most SDS Bits Quit When They Hit Rebar
Reinforced concrete is exactly what it sounds like: concrete with a steel skeleton running through it. That rebar is there to give the structure strength, but it's also the thing that ends most SDS bits' day early. A typical bit is built to chew through concrete which is soft, brittle material, and simply isn't built to keep cutting once it meets solid steel. When it hits rebar, it stalls, and you're stuck starting over in a new spot.
That's a real problem on jobs like sewer drain penetrations, where you don't always get to pick exactly where the hole goes. You need the hole where the plans say it goes. Rebar or no rebar.
The Bad Dog Difference: It Drills Straight Through
Bad Dog's 12" SDS bit, part of the 6-Piece Bad Dog SDS Hammer Drill Bit Set, is built for the job site reality that rebar shows up whether you planned for it or not. Unlike other SDS bits, this one drills straight through rebar without stalling out or giving up. One hole, start to finish. Concrete, rebar, and all. No repositioning, no second attempt, no wasted hole in your work.
That's the difference in practice: instead of pulling the bit and drilling again somewhere else, you keep going. The hole you needed is the hole you get.
Built for Jobs Like This
This isn't a bit for delicate work, it's a bit for thick, reinforced concrete on real job sites. Drilling a hole through a sewer drain isn't a light-duty task, and the material fights back the whole way. That's the kind of application this bit is designed for. Full-depth holes through heavily reinforced slabs and structures where hitting rebar isn't a matter of if, but when.
