Fantastic. With a hammer drill, it made quick work of the 6in deep holes I drilled into my deck piers. Although pricey, I’m hopeful it will last me a long time.

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!!

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.

This star bit for concrete is a really good investment. It goes thru concrete like a hot knife thru butter. I used a hammer drill and this bit to drill 13 holes and it took me only 15 minutes to drill them all. The bit is well made and the star on the cutting end does on heck of a job at cutting thru the concrete. After using this bit to do all 13 holes, its still very sharp and I am sure it will cut many more holes as needed. The bit is well made and the length lets me choose the proper depth that I need to go. I had tried other bits but not with the success that this bit has. This will be my go to bit from now on. Great investment. Highly recommend this tool.

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.

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
