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

Did the job. Used this bit in my rigid hammer drill. Struggled penetrating the concrete with it.

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.

The Milwaukee 1/4 in. x 6 in. MX4 SDS-Plus Carbide Bit did a great job drilling holes in my cement wall. I needed the hole to mount a stainless steel handrail. The carbide bit went into the cement as easy as a regular bit into wood.

Exceeded expectations for drilling through stucco and concrete sidewalk.

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.

Cut through my 8″ 80 year old foundation like butter.

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.
