Purchased this to drill a 6” diameter sewer drain hole through a 6” thick foundation stem wall and it only took about 45 minutes !! Worked perfectly for the job it needed to accomplish

I used this bit to drill through a 6” slab so I can run 3/4” PVC through the slab and this bit did the job in about a minute. I set my rotary hammer to the hammer drill setting and it was very easy to punch through

Bought this to perforate a 18″ thick, double stacked limestone wall so we could breakthrough. Most people think Limestone is soft but it’s actually very sense and this bit drilled right through it. About a minute, give or take, per hole to go 18″ with a small Makita SDS. Excellent buy. Even after what was 130 holes through Limestone, it’s still like new going through concrete. Great buy.

I purchased this to finish drilling a hole through a foundation. Lucky me, not , there was rebar where I had chosen to drill. My other bit was stopped cold at the rebar. I hesitated to use the new bit but had to get the job finished. It plowed through rebar and very hard concrete like it was butter. I will be replacing my older bits with these.
