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.

Used my Bosch hammer drill and drilled through an 8″ foundation wall in about 15 seconds. Worked perfectly.

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.

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.
