    Your review:
    I had about 40 5/8” holes to drill in a new foundation. My old hammer drill was acting up and took almost 2 hours to drill 5 holes. Got this unit and it took 3 to 5 seconds to drill a 4” deep hole. It’s a great tool

    Amazing drill, great value and power for the price
    Your review:
    I've used this drill for 1.5 inch holes in granite. It has worked amazingly well, and I've drilled about 100 holes so far, each 10 inch deep.

    Great drill
    Your review:
    This by far the best drill I’ve used for concrete drilling, it has the perfect speed and hammer action for all concrete drilling.

    Break down after two gentle use
    Your review:
    Bosch’s quality is not reliable anymore. When it works it did the job, but reliability is a joke. Stopped rotating after two gentle use on drilling the hole for Rangehood. Contacted Customer service via message but said out of warranty which is only one year. I cannot find the receipt so Homedepot declined the return and Bosch asked for receipt. Researched online and probably the brushes problem. Can’t image so heavy duty hammer stopped working after that dental use.

    Great tool
    Your review:
    Plenty of power and not overly heavy, exactly what I needed. Breaks up concrete no problem.. used it for hours and didn't feel it getting warm at all. Only had it for a month so I can't speak for its longevity but i don't see this thing crapping out, built like a tank. You can't go wrong with this tool

    Best tool I own
    Your review:
    I bought this tool primarily for chipping concrete but it also found it very effective for digging holes and trenches for gas lines in the Arizona desert. This hammer pays for itself in full on a weekly basis. I have a massive amount of tools this is the only tool I will not let anybody touch I'm still giving this Hammer 5 Stars even though there's one thing I wish it had but doesn't and that is the ability to lock the trigger button. Sometimes I am working this tool for several hours at a time with very short breaks in between and wears my forearms out. If you don't have one of these get one you'll find plenty of uses for it
