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.

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.

Great bit. Strong, powers right through the toughest concrete and small metal with ease.

Bought this to perforate a 18″ thick, double stacked limestone wall so we could breakthrough. Most people think Limestone is soft but it’s actually very sense and this bit drilled right through it. About a minute, give or take, per hole to go 18″ with a small Makita SDS. Excellent buy. Even after what was 130 holes through Limestone, it’s still like new going through concrete. Great buy.

Had to bore 26 holes in year old concrete. This bit exceeded my expectations. The last hole drilled as easy as the first. Would definitely recommend!!

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.

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.

Serious carbide tip on this bit….excellent results and anticipate that it will produce predicted great results for a long long time. Pricey, and worth every nickel.Recommend

Works beautifully. I install this bit, hold the rotary hammer with one hand and let the bit do the work.
