Packs power & great features!
As a Handyman I have a huge array of tools since I’m a multi purpose handyman and Bosch is definitely a name I try to keep on hand. This is my first time experiencing The Bosch D-handle Bulldog Hammer Drill and I have to say I am very impressed with it. This drill packs a lot of punch and power.

This Bosch drill is cordless and lightweight and delivers 1.9 Ft-Lbs of impact energy. I really like the side handle and how it can be held in a variety of positions. This drill is great for drilling into concrete and i didn’t expect that much power from a battery operated drill. I drill into a lot of heavy reinforced concrete and this works smoothly. It comes in a plastic case so you can easily organize everything and makes it much more convenient to travel with from job to job.

The drill has a lot of benefits and features including a light to help you see better, brushless motor, D-handle design, kickback control technology, robust power system, and only weighs in at 5.8 pounds. This is going to be my go to hammer drill as of right now and I definitely think it’s one of the best cordless drills on the market. If you need a drill that packs a lot of power and is convenient I would recommend the drill.

A Must Have Tool!
I recently used the Bosch 18V EC Brushless SDS-plus Bulldog 1 In. Rotary Hammer Kit and cannot say enough good things about it! It is easy to use and has helped saved me so much time and effort on so many of my work and home projects. I found myself continuously reaching for it over others I own and it is now the one I prefer. It is by far, the best cordless hammer drill I have ever used! This it is a must have tool in my tool kit!

EXCELLENT!! Made a difficult job easy!
We had a gazebo project that went smoothly with this tool. My husband said the rotary hammer felt comfortable in his hand with the soft, non slip handles even when using for longer periods of time. It performed flawlessly with the high torque motor. This Bosch Bulldog tool has 3 modes, "rotory only", " hammer only" and " rotary & hammer" modes which gives you the option to choose which mode will be most convenient for the job. All of these are controlled by a locking dial knob. The depth gauge makes it easy for you to get to your desired mark without over drilling. Stability and control is provided by the forward grip/ handle. The forward grip/handle can be rotated to accommodate left or right handed people. With this being cordless there is no need to worry about a cord being in the way. The project which was securing a gazebo, one fully charged battery gave us the ability to complete almost the whole project. Keep in mind that we were drilling through concrete. For larger projects like this, I highly recommend purchasing a second battery. This whole Bosch rotary hammer kit is awesome and really helped to make this job easier. I highly recommend it, this would also make a fantastic gift!

I trust this tool to get the job done
I'm really impressed with this rotary hammer. I know that Bosch makes great products, so I had high expectations for this, but it truly did exceed my expectations. I work in construction and do a lot of DIY around my own property, so I am always in the market for tools that will help me with the big jobs.

I found this rotary hammer/drill to be a bit heavy, but in the best way. I feel confident that this thing can tackle a tough job and not break down on me. There's an option for a second handle, which helps with the weight of the tool. I also loved the placement of the LED light, because I often work until sunset and need that extra brightness to finish up. I've used this drill on several different materials and it has worked perfectly on every single one. I have yet to find something that this tool struggles with.

It is a well made, tough, sturdy, reliable rotary tool and it will be in my tool rotation for many years, I"m sure.

Best Hammer Drill I've Owned !
I absolutely love this Bosch GBH18V- 26DK15 Hammer Drill. It's at least a good 10-12 seconds faster than my other corded hammer drill. I love the D shaped handle as it allows me to drill above, below, and at various angles sideways. I love that its cordless so cords and extension cords don't get in the way while I'm working. Comes in a nice molded plastic case for when it's not in use. Being in construction, I regularly use a hammer drill especially during remodel jobs. So far this one has held up nicely when compared to all the other hammer drills I've owned. This is my first cordless one and only time will tell how long the battery will last. It comes with the corded charger and it did go to a full charge overnight. It lasted my entire shift which was 8 1/2 hours using it intermittently. I was surprised how well it held up. I also like that it has a nice light that comes on while you use it. Makes my work that much easier. I would definitely recommend this cordless hammer drill to my coworkers. In fact a few of them used it and really liked how it handles and are planning to buy one of their own. Great value and over all a great piece of equipment.
