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.

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.

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

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

Never used Milwaukee drill bits before, assumed it wouldn’t be any different from other brands I have used, notably Bosch and Irwin. Although I didn’t get to use the bit in a heavy duty fashion, the limited experience was very positive. It drilled through cement board and cement block easily. My only regret is that I didn’t make the purchase sooner because it could have saved time/energy on my project.
