The first thing you'll notice about Bosch's rotary hammer is its great ergonomics, which clearly were a major consideration in the design of the hammer. The grip and trigger mechanism are well integrated, especially the front grip, and long enough to accommodate different body styles (I've got long arms; my buddy is the opposite: we both liked the tool's feel). For a rotary hammer, design is especially critical during overhead and down-drilling operations, where fatigue can quickly rear its ugly head. The tool's vario-lock positioning is great; it gives you 36 different working angles to choose from so you can modify the tool to fit the application. Likewise, the hammer offers three operational modes: hammer only, rotation only, and hammer with rotation. We really appreciate the self-contained dust removal system, which does a great job of keeping the mess to a minimum. Are there drawbacks? Not many. The bit-changing mechanism is a little stiff and a little cumbersome, perhaps--but that's a pretty minor negative in a tool that otherwise provides such pleasant operation. The people at Bosch really know what they're doing, and it shows in this tool. --Michael Shilling ... Read more

Good but not the best
I use this hammer drill to place expansion bolts in stone for rock climbers. My experience in hard sandstone is that the tool will drill around 10 holes with a new bit, 3/8" by 4" deep before needing a recharge. It's light and fast and seems to be fairly durable, a big improvement over the old Bulldog. But when it comes to real power in a cordless hammer drill think Hilti as in model TE5. I used one of those a while back and although a bit heavier this thing drilled 15 holes and was still going strong when I had to quit. ... Read more

Power For Digging
I bought this product for digging. I also appreciated the contractor review previously done. I live in an area with poor soil and needed something that was easier to use than a pick. I got the spade and chisel bits. This rotary hammer works great. I dug holes or 8 plants in 20 minutes...and the machine did the work. The cost was well-worth saving my heart and back. I'm sorry that I didn't buy one of these 10 years ago!

Biggest bang for the buck
Rotary hammers are a big buck item so its important to consider all of them. I use this Bosch hammer in my electrical contracting business. Its small enough to handle easily and it is built to minimize the vibration that comes with drilling concrete. It can drill through concrete up to is specification and handle ground rod driving too. Buy this unit and the Bosch bits but consider the DeWalt accessories, like ground rod driver or spade bit, because they are usually less money. ... Read more

Bosch is it for Rotary Hammers
I've owned an earlier version since 1982. It's taken more abuse than you can imagine. Other brands just don't compare to Bosch's.

The best spline drive hammer you can buy.
I had one of these hammers for years. Let me tell you it's one tough tool. We abused it. It's made primarily for drilling with light chipping as an option. As a drill it excells. Faster than Milwaukee, DeWalt, Makita, Hitachi. For its weight it hits hard. Where we abused it was in using it as a chipping hammer or more accurately a breaker. As a breaker it's pretty slow. So it would run for hours on end breaking concrete out in basements to access plumbing. The tool never gave up. It ran as good the day I sold it as the day I first took it out of the box. It was so used that the rubber grip on the handle was gone. I still got 175.00 for it. Why did I sell it? I upgraded to SDS max. It's better than spline. When they invent SDS super duper max, I'll probably upgrade again. If you have a lot of spline steel, you can't go wrong with this tool. If you don't,Buy the 11230EVS or the 11235EVS. The SDS max system is tighter, smoother and faster drilling than spline drive . ... Read more

NO SUBSTITUTE!
This Bosch demo hammer is one of my most often used power tools. I am a landscape contractor in Northern California, often bidding work that I can't see, (underground sprinklers or drainage systems for instance) and encountering many unexpected obstacles.

This Bosch hammer has been a lifesaver when it comes to cutting through layers of concrete and rocks, chipping out concrete "overpour" and removing things like old fence post bases.

With the clay spade bit, it also comes in very handy when digging up compacted soil (typical of a lot of new home sites.) The adjustable handle works well in close quarters, allowing for approach and attack from different angles. The SDS-MAX bits are a breeze to change, and allow for switching some bits with other tools (my Bosch rotary hammer for instance.)

All told, this demo hammer is versatile, reliable, and indispensible for finishing out trenches, foundation work, and demolition of concrete and asphalt. Contractor friends of mine have had theirs (including this model's predecessors) for years. It's a tool that retains it's value in the long run, for which there is no substitute. ... Read more

good drill for the money
Bought this drill to install a hand rail on the in-law's porch...50 year old concrete...and had no intention of using a start drill for the holes. Altho the drill seems to get hot pretty quickly, given the angle that I had to be in to drill the holes, several breaks for ME were needed anyway.

it gets hot
I recently purchased this drill (the 1194VSRK) and it works pretty well. However, it gets HOT extremely easily (after a couple of minutes.) Does this happen to everyone?

Great value
I picked a reconditioned one up at a local hardware store(7-corners, the KING of all hardware with the largest tool selectionin the world) What a great value. I've used the milwaukee hammer drill, and it is a little shorter and easier to use, but I am really a moderate user - not a contractor, just a hard-core DIY-er. This is a great value over the milwaukee (which I've used), although the milwaukee is the standard by which I judge. Hence the four stars. I have a bosch 3/8 drill and a bosch planer, and have had a bosch cordless drill. They all perform wonderfully. Overall - a good value, quality name and construction, nice case, good for serious hammer drilling as well as all-purpose 1/2 drill work.

Great Drill, wrong specs
I needed this drill to make 3/4" holes in a 16" thick rebar'd concrete wall to run water pipe. so far, not a single hiccup. only thing i fault is that the description says 8.5 amps when the drill, by the ratings on the drill itself and the Bosch website are only 6.0amps. other than that, nice drill

Great Drill.... Buy It!
There are many corded drills out there to choose from but you can't go wrong with this one. Here's a very solid, powerful machine which has stood the test of time both in my own work and in the market, and which continues to be a great buy at only $160. It's been a workhorse for me both as a hammer drill and in timber framing, driving large bits through thick timbers with no trouble. The auxiliary handle and the depth gauge are simple, strong, and easy to use. I only use a different drill when I need to do right-angle work. You can feel safe buying this quality Bosch tool. ...
