Background
The Ridgid Hammer Drill #R8611501 was a cordless 18V hammer drill released in 2015. With an average rpm of 0-450 and average hammer bpm of 0-7,200, it was meant for drilling into wood, metal, and masonry. It was sold in a combo kit for $270 that included 2 batteries, a charger, an impact driver, and a duffel bag for storage. The Model #R8611501 is notable for its LED headlight and comfortable 8 3/8 inch side handle. According to the Journal of Light Construction's review, the drill is "fair under heavy duty uses," but is "better suited for moderate service." They also note that the LED headlight can be turned on without pulling the trigger and the side handle conveniently attaches to the drill without sliding over the bit and chuck. However, the drill has notable performance quirks, such as its lack of a belt hook or mount, a long delay after stalling, and a sensitive battery overload circuit that would shut the tool off without a warning to the user.
