Great Drill. Very nice quality. Case could be a little more rugged. Not like the cases of the past at all, sorry to say.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!!

I had to drill some holes in a concrete wall. It did the job quick. It could also hold a chisel and work in hammer mode. You could use this tool to carve marble for artwork. It's awesome.

Había estado comprando todo en Amazon por la idea de buenos precios, al paso de dos semanas después de la compra me doy cuenta de que pagué hasta $2,000 más, por lo que no consideraré nuevamente a Amazon para estas compras. El rotomartillo un poco débil al tacto, buena potencia, excelente ergonomía.

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.

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!)

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!

Love it, drilling holes no problem, removing tiles none only thing was that I dint feel all the vibrations because the Counter-balanced vibration control at the time but I did it later on my shoulder, first time I use a drill with this feature, and feels different, more comfortable, even used for taking solid wood frame doors and windows from brick made walls was easy using the chisels that I buy from the set HCST006, I used on brick walls, for drill on reinforced cement concrete columns also on beams, i also buy the Bosch 1618571014 SDS-plus Shank 3 Jaw Chuck And I used with the traditional drill bits and worked fine Now I want to see Wat can I do on wood, I am that kind of person who cares about the design and the look of the tools and this one it is very pleasing for me, very well made, Germany made, good case for storage, I am very pleased with this tool

Well I don't leave many reviews but I felt I needed to in this case. I've been a professional contractor for 19 years now and in that time I've had the privilege of using great tools that outlive expectations and the nightmare of using tools that fail to meet minimum standards, both of which come from the top brands. I have an extensive collection of hand and power tools that I've used throughout my years that tell the tale. So in this case with this drill let me start by saying I have owned one of these since 2015 and so far I haven't crossed paths with a task this tool can't complete with ease (you name it we've and we've pushed this tool passed it's limits)! I purchased 4 more of these, 2 from Amazon and 2 from Lowes, to demo 1500 as ft of glue down hardwood (on this job we couldntg use our trolley carts or floor remover machines due to foundation issues). For 3 days approx with 5 men running one each for 9 hrs a day mostly non stop breaking up this floor pushed them at least I though to a limit, but did it? NO not at all, these drills got warm and even leaked some grease but kept on working like a beast and sealed right back up. Im still blown away at the power of these as well as the shear unforgiving stress and the beating they can take while never slacking up outperforming any expectation I had in mind knowing what they were about to be subjected to!! I had allotted for these to be a job expense (no good after job) in my bottom line but folks I believe they haven't even been broken in yet. Like I stated before I don't review many items because time is money but I truly felt like this tool was worth my time in writing a review, so if you want a drill that's a workhorse and a beast during that load then it's right here and you will not need to look further!! Tested and approved folks!!!!!
