This masonry SDS drill with quad cutting tips performed beyond expectations. Well worth the money by saving time and labor .

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.

Great quality. Drilling through a garage floor is not always easy but this carbide bit went through all the hard and soft spots with ease. I had to drill 6 holes 6” deep and the bit still looks great.

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.

Works beautifully. I install this bit, hold the rotary hammer with one hand and let the bit do the work.
