Update: What was I thinking all of these years. This thing is so nice to use! Tons of fun compared to my old Ryobi piece of garbage. Cuts like butter and with ease!!
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 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.
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.
