Bosch GBH18V-26 18-Volt Brushless 1 In. SDS-plus Bulldog Rotary Hammer

Lithium-ion, advanced electronics and brushless motors have changed the rules of cordless tool.  Today’s 18volt cordless tools simply crush their earlier compadres from years past in both power and runtime. The Bosch 1 Inch SDS-plus Bulldog Rotary Hammer is no exception.

Bosch is one company that is regarded in concrete drilling. Its SDS or “Special Direct System” drills are often the preferred tool for contractors drilling in concrete. These SDS tools are usually corded, heavy and powerful, the Bulldog is only one of those things, it’s powerful!

Brushless Motor

Bosch is working hard to “cut the cord,” on their high demand tools like SDS hammer drills. The Bosch 1 Inch SDS-plus Bulldog Rotary Hammer was designed with a brushless drop motor, that surpasses earlier generation cordless tools by 50-percent in impact energy and run-time.

The brushless motor has advanced features such as an Electronic Precision Control, for smoother bit startups, allowing for a slower ramp-up for accurate bit starts. It delivers 1.9 Ft.-Lbs. of impact energy.

Bosch has hit a home-run here, and this cordless drill is the closest thing to a corded tool, I’ve seen them do. Truly impressive.

The tool has an L-shaped design which helps facilitate horizontal, shoulder height drilling, and the spring built into the handle, is an obvious part of their vibration controls, designed to reduce user fatigue.

The tool, like many of the higher end cordless tools these days, has built in electronics that monitor the motor and battery, protecting both from overheating and overload.

It produces 0-4,350 no-load BPM and 0-890 no-load RPM.

Kickback Control

The Bosch 1 Inch SDS-plus Bulldog Rotary Hammer has a Kickback Control, that uses a sensor to stop the tool from rotating when bind up situations are encountered. If you’ve ever been the recipient of a drill kicking back, you will appreciate this feature!

Lightweight and Powerful

The Bosch 1 Inch SDS-plus Bulldog Rotary Hammer measures 13.7-inches long, and weighs 7.7 Lbs., but don’t let its small size fool you. It delivers 1.9 Ft.-Lbs. of impact energy, for an outstanding impact-to-weight ratio. How’s for a strength to size ratio? That’s the equivalent of 10 pounds of muscle in a 5 pound bag!!

Overall Thoughts

The Bosch 1 Inch SDS-plus Bulldog Rotary Hammer is a perfect tool for those everyday mid-sized drilling applications. While it will not take the place of my larger SDS drill, it sure does handle most of the mid-level tasks I do, and does it in a lighter package.

For me the biggest takeaway is that I can now use a cordless tool, that is lightweight and powerful to get 80-90% of what I do accomplished.

We were super impressed with its weight to power ratio. Again, don’t let this small drill fool you, it’ll get the job done and you may even enjoy yourself in the process!
