This review is from: Bosch 11255VSR BULLDOG Xtreme 1-Inch SDS-plus D-Handle Rotary Hammer (Tools & Home Improvement)

There are several reasons why this drill is better than other hammer drills I have (Craftsman and DeWalt). The way Bosch designed this drill let a lone the power it has, makes it stand alone. I'm not going to dwell on the power ( even though I was able to completely chip away a shower mortar bed in less than 10 minutes), what made the difference is the design. First let me say that quick change SDS chuck and bits make this worth while. If you have done a lot of drilling you know how frustrating it is when you have to continually stop and re-tighten bits that have come loose from binding in the concrete. SDS eliminates this, along with the ease of the quick bit change also prevents the need to keep looking for a chuck key. Not once did I have the bit loose up.

Bosch also made it easy with how they implemented the auxiliary handle and depth guide. Other manufactures make you completely remove parts in order to change the handle position or change the depth guide. Another excellent feature is the Vario-Lock which will allow you to change the orientation of the chipping bit without having to hold the drill or yourself in awkward situations that might even be dangerous.

The clutching mechanism actually works very well. The times when I did bind the bit (which was rare with the drill power) I had little torque transfer before the clutch caught. Which is comforting from a safety aspect.

For the power, the drill is comfortable with a decent length cord. I haven't been using this drill long, so I can't speak to the reliability. Regardless the design and power has me sold and I've been using DeWalt for years.

Also one thing that is a pet peeve of mine (although minor) is the way manufacturers position the outlet of the power cord. Most make the power cord come out directly behind it, making it difficult to put in the case and in some cases having to severely bend the cable which can cause damage over time - this Bosch drill doesn't have this problem.

Keep in mind this drill only works with SDS bits, although Bosch sells a separate chuck that will allow for normal bits.

This review is from: Bosch 11255VSR BULLDOG Xtreme 1-Inch SDS-plus D-Handle Rotary Hammer (Tools & Home Improvement)

I am in the construction business and i can tell anyone who is looking at this product that it is truly an indispensible tool. It drills through brick and concrete with ease. It is relatively light for its power and size and is very easy and comfortable to use. At this price point you cannot do any better. Highly recommended.

This review is from: Bosch 11255VSR BULLDOG Xtreme 1-Inch SDS-plus D-Handle Rotary Hammer (Tools & Home Improvement)

I bought the Bosch 11255VSR in order to demo 6" thick concrete on top of my chimney. I drilled about 50 holes all the way through with a 3/8 inch SDS bit in about 10 minutes. My small Makita hammer drill could barely dent this concrete. I have 3 of the SDS chisel bits for this drill and I used them in hammer mode to knock that concrete out completely. Not sure how I could accomplish this job otherwise. Anything bigger would not be safe up there and anything smaller couldn't make a dent. Defintiley a keeper. I notice that some people have commented on similar Bosch models that the depth gauge is plastic. This one comes with an aluminum depth gauge which seems plenty strong, although I don't need it for my current project.
