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

You have to be kidding me… we are talking about a Masonry Drill Bit.

This bit ate right through my 10-day old concrete footings without breaking a sweat. Drilled 9 holes @ 5/8” diameter about 5.5” deep and each hole took maybe 10 seconds. Didn’t encounter rebar so I can’t speak to how well the bit cuts thru steel, but for concrete, it was great. I don’t have the need for drilling 5/8” holes in concrete often, but you can’t go wrong with this bit.

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.

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.
