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

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.

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.

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.

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.
