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 was disappointed that this didn’t stay sharp longer. I know hammer drills are hard on bits … though I only had eight holes to drill in old brick.

Had to bore 26 holes in year old concrete. This bit exceeded my expectations. The last hole drilled as easy as the first. Would definitely recommend!!

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