The classic and best for the value. Very heavy duty, much better than normal hammer drills.

Powerful, safe, fast, easy to use
I purchased this product after owning the earlier version, same company, same drill, but lacking the SDS technology as well as the anti-kickback protection. Like my prior model, which I've owned for maybe 20 years, this new model is a beast. The new SDS technology significantly improves the drilling speed since the new drill bits, which float in a collet, rather than being clamped in a chuck, are way more aggressive and effective in vertical hammer strokes which penetrate much faster. Huge impr...

Disappointed With Lowe's Handling of Veterans Disc
I visited the store a week before I decided to buy. I took this tool up to the customer service area. I asked what the Veterans Discount would be. I was told the final price would $225 after the discount. A few days later I went to this Lowes store to buy the product. At the checkout, I did not get the Veterans discount. I called over the Lowe's checkout assistant to inquire why it did not give me the discount, and I explained that I had checked with them a few days earlier. She looked it up and...

Worked perfectly
This drill worked perfectly for my application...drilling into a block wall that has a rock facing using a 1" diameter bit. In the future I will also use it with a spade bit for chipping rock, mortar, and concrete.

A must for drilling in concrete
Great product! Just got my second one. The first one is almost 20 years old and still works fine.

Powerful and makes the job easy
After trying to use my handheld smaller MIlsaukee hammer drill, I finally relented and I bought the Bosch Bulldog 8.5-Amp SDS-Plus Rotary Hammer Drill specifically to install railing posts into concrete stairs because the Milwaukee just wasn't cutting it (pun intended). This drill exceeded every expectation. As opposed to the small handheld drill that I didn't even manage to drill down a few inches with, this drill cut through the concrete like butter, making what would have been a tough, time-c...

Good balance and power
I have been a big fan of Bosch tools for years. My previous Makita hammer drill eventually died on me. I'm glad I spent the extra money on this tool. I've used it a few times with multiple functions. I've used the chisel just as a hammer as well as a hammer drill function and have been very impressed with the balance and the power of this tool.

From Skeptic To Believer: IT WORKS!
10 seconds to drill 1/2" diameter hole through a 4" concrete pad that was poured in 1954. The Milwaukee Magnum 1/2" drill with a hammer drill chuck I was using was burning bits, taking a ton of my weight and pressure and about 7 minutes to get it done. I had no clue a rotary hammer drill with sds plus was that much better. This Bosch tool ran so well, with no uncomfortable vibration, and drilled through the concrete so effortlessly that I thought it was magic. I went from hating drilling the nex...
