Bosch 11250VSR 3/4″ SDS-Plus Rotary Hammer Preview: A Review

The Bosch 11151 VSSR-RT is a small rotary tool with a bit of a reputation. It’s not cheap, but it does offer some great features.

I’ve used one before at work and found it to be very useful in drilling holes into various materials such as wood, plastic, metal etc.

I was looking for something similar for my shop so I could do simple jobs like removing rust from bolts or tapping out nuts without having to go through the hassle of using a drill press. So far, I haven’t been able to find anything comparable (or even close) and while I’m sure there are others who have had better luck than me, I wanted something that would last longer and be easier to use.

So, I decided to give the Bosch 11250VSR 3/4″ SDS-Plus Rotary Hammer Preview a try. The price wasn’t bad either!

First Impressions:

When I first opened up the box, I was surprised how heavy this thing is. It looks pretty much exactly like what it sounds like – a rotating sander with a large circular saw blade attached to it.

In fact, when I first used it, I kept expecting the whole thing to be unbalanced and go flying out of my hands since there was no cord or wire coming out of the back (you’d be surprised how often you catch yourself checking for these things).

The entire tool is also pretty noisy. The spinning circular saw blade makes a lot of noise, so do be careful of where and how you’re using it.

The instructions were actually pretty easy to follow and I didn’t need to guess at any of the diagrams. I just needed to make sure I was careful when handling the blade since it’s a lot sharper than I thought it would be!


Motor: The 11250VSR has a 3/4 HP, EC and OHC motor that operates at 11,500 RPM. The speed is important and this is one of the faster models out there.

Ease of Use: The unit itself is pretty easy to use. You just connect the saw blade to the front of the motor and then select one of the six possible positions depending on what size hole you want to drill.

It’s as easy as turning a dial.

The handle is also very easy to grip and doesn’t cause any fatigue even after prolonged use. It’s not too heavy either, weighing in at only 8.1 lbs (shipping weight is 19.2 lbs).

Power: This thing is a beast at 3/4 HP. The last model I used only had 1/3 HP which was quite a jump in power.

At this level, it can easily handle drilling through wood or breaking through metal. It was even able to handle through a cobbled stoned wall (over time, but it still did the job).

Portability: At 8.1 lbs, this isn’t the lightest model but it’s still pretty easy to transport from place to place.

The only thing that I’ve found is that such a solid, heavy piece of equipment does tend to leave a dent in your floor if you drop it from a height! So do be careful when using it indoors.

Special Features: The thing that makes this model really stand out though is the six different drill sizes you can use. You can choose from 3mm, 4mm, 5mm, 6mm, 7mm and 8mm, making this a very versatile tool that can be used for a wide range of projects.

Once you’ve chosen the appropriate size bit, all you have to do is turn the dial to select it and then start drilling.

The 3/4″ Keyed Chuck also makes changing bits a lot easier and means that you don’t need any separate adapters to use the different sizes. In fact, all you need is a standard drill bit (or whatever size bit you want) and you can quickly and easily make your own custom bit with the chuck.

The only thing I wish the unit had was some sort of mechanism to keep the drill bit from slipping out. The saw blade does this by having those small teeth along the edge that catch and hold the wood as it’s being cut, a design like this would be very useful for drilling as well since drilling metal and stone can cause the bit to want to slide out of place, throwing off your accuracy.

The Verdict: All in all, this is a great tool that I’ve been enjoying a lot. It’s not the cheapest model out there but in my opinion it’s worth the price (and more) thanks to the 3/4HP motor and the six different bit positions.
