Good Tool!
Rating: 5
The drill is balanced and comfortable to use. I like the longer cord making it more convenient than hunting down an extension cord. The drill has plenty of power and I like the hammer drill, both functions operate perfectly. The drill has plenty of power (using a 6" hole saw I needed the side handle due to the strong torque). The drill came with a depth gauge, chuck wrench, rotatable side handle and a nice case. The only potential problem is the side handle is difficult to tighten, having a rather small wing nut making it difficult to snug up.

Like it big time!

Bought it to help build a small wooden deck over a concrete base. Drill was used to anchor screws and bolts to substrate. Found it to be very reliable and powerful. Cut overall job time considerably.

only had it for a few months and just love it. i have a regular bosh drill i purchased 15 years ago and still works great. had to change the chuck once and that is understandable. no other maintenances were done.

Fine product

Sturdy, yet light, this drill does a great job. A switch on top allows one to use it as a regular drill or as a hammer drill. Good buy for the money. Nice case, as well.

I bought it to mix cement and grout for tiles and to replace/support my old drill. Along the way I used it to drill tiles. It is strong and easy to use. So far I love using it.

Simple and aggressive
Rating: 5
First time using a hammer drill, so it is a bit aggressive when at max speed. I used this adding a 2/4 wall on my cement foundation. My holes would be 1" deep. I had my concerns being too aggressive, as I didn't want to harm the motor or damage the drill bit. Not making much progress, I eased into being more aggressive and let the drill do its thing. My first hole took about 10 minutes. Afterward, my next holes took about a minute each. As a practice, I counted to 10 seconds then cleaned the debris.

Did the job well!
Rating: 4
I used this hammer drill in framing my basement, attaching base plates to the concrete floor. It worked very well on the full job. The drill has plenty of power and torque for the job. Our only problem was stripped Robertson screwdriver heads when drilling in screw. We burned through quite a few screw drivers as the torque was so powerful. I subsequently learned there are specialty bits for the diver that may be more effective. But ver satisfied with the power of the tool itself.

Powerful motor.

I wanted to drill holes in some concrete steps to mount a handrail. The concrete is about 20 years old so getting pretty hard by now. The hammer drill worked really well, much easier than I expected. It went so well that I was able to surprise my wife with a new handrail when she came back home after a morning trip out! Lots of brownie points!

Not quite what i was hoping for

I bought this tool to drill some weep holes in a concrete deck. It performed well enough for its design. I had to rent a roto hammer to complete the job. Am keeping it for normal drilling into concrete walls for fasteners and such.

Like Butter!
Rating: 5
This drill makes holes in concrete like butter ( just make sure you hold it straight, and don't hit any re-bar!). I put 15 holes through 8 inches of concrete in a matter of minutes, just make sure you tighten the auxiliary handle well or the tool will spin on you! Comes with a large case that holes extra drills, and a really long cord (~ 10 ft.). The variable speed is handy as well as the hammer only mode ( I would also like a drill only mode as well a a reversing switch). Fine tool although the cardboard shipping box could be more robust and some foam inside the case to keep the tool from sliding around during transport.

I just used my Bosch 850 hammer drill for the first time taking out 16 SF of concrete to lower a shower floor. It helped do the job performing much better than I could imagine. I love this hammer drill.

Nice upgrade
Rating: 5
This drill is replacing a Bosch11240 that has drilled a lot of anchor holes over the last 9 years so when it came to getting another drill it was going to be a Bosch. We gave the new one the workout this weekend anchoring down tracks and this drill did not dissapoint and is much more comfortible to use, nice tool.

Reliable Rugged Tool

We have three of these hammers in use and they get put through paces every day. These hammers take a beating with very little down time or repair. Definitely worth the money.

Great Bosch Hammer
Rating: 4
Great tool , use this almost every day for a few hours. i did have a issue with the fan making contact with the baffle and it melted together and seized the tool. took it in for warranty. a few days later got it back and it has not failed since. and that dates back almost 2 years. Very happy customer.!

Good Hammer Drill For The Price
Rating: 4
I use this primarily for light demo on concrete. This tool works well for chipping and removal of concrete around stub ups. It is light enough where it won't wear you out after 10 minutes of hammering. Good tool at a great price.
