I bought this to break out concrete in my driveway. It will drive a 5/8” bit through the old concrete like butter.

The modern 3600- psi concrete wasn’t keen on yielding to the bit. So I loaded it with a pointed chisel bit and set the tool to hammer-plus-drill and voila, mo’ buttah.

Then back to the 5/8 drill, kept that setting, and off we ran.

This drill is versatile and strong. And not heavy.

The instructions say to oil the ends of bits before chucking them. I’m using a couple of drops of three in one oil. No issues whatsoever, and lots of success.

I priced out hiring this work. Way too expensive. This and the bits are a fraction of the price, and I’m getting exercise!!!! And I get to keep the tool. Unless I do something totally messed up, this will last me forever. (I just knocked on wood!)

I was trying to mount brackets to concrete steps using a milwaukee 18v impact and same brand masonry bits, it sucked, for hours and hardly any progress.

I bought this bosch hammer drill and some cheap SDS plus bits from harbor freight and literally had the job done in minutes.

This hammer drill is amazing.

It just arrived yesterday. Today I drilled eight 1/2" holes in a concrete slab in about 30 minutes. Wow. Super easy. I could have done it faster but I didn't want to risk overheating the tool and I'm still just getting used to it.

The vibration wasn't bad at all (I'll see how my elbows feel tomorrow). Do wear goggles, respirator and ear covers. It chews thru the first layer and flings small concrete chips everywhere. Once it's below the surface, the concrete dust just keeps getting piled up around the bit.

I'm very satisfied. It was fast and really very easy. I've been renting a $65 per day tool that I guess is much more than I needed (but but the only model the big box rental place has) since it's 3x the size but they both do the same job.

I also needed to chip out a small section of concrete above the slab. Between this tool and a mallet it only took a few minutes once I figured out the technique. Sweet. If it works on concrete slab it should drill through masonry (softer) or mortar (softer) like a knife thru butter.

This made my tile removal job a breeze compared to my last adventure with an air-powered chisel. It’s very powerful, and was great for the job. It’s variable speed capability is the reason I bought it compared to the Dewalt, and I’m glad I did; it was a must-have feature for what I needed. The only concern is that the shanks that I used acquired some grease that seeped from the tool after intense use. But now the job is done, and I have a great tool to use for any future projects!

I should have bought this years ago. I’ve been struggling to drill holes in concrete, brick and rock for years. I got this drill for a project that required removal of bricks that would need replacing afterwards. In addition, I needed to accurately break out bits of concrete blocks. This drill, combined with the right bits, chisels and a mortar knife made the job really quick and easy. Learning to switch between features was easy. If the Bosch quality is the same as it has been in the past for me, this should last me years!
