Got this through HD not amazon, but recently purchased some bits through amazon so thought I would share my thoughts about this drill. Similar sentiments to other reviewers. About the most powerful rotary hammer you will find with 15amps, have had this for about 3 years now and used on several occasions and has performed flawlessly. Drilled about 200 3/4" x 4-5" holes for concrete anchors and this drill made cake of it. Recently used it with a 6"x25" scraper to remove 1500sq ft of the hardest glue down carpet+pad I have ever come across. Drilling through brick you have to be careful or it will pound it into oblivion (i.e. big chips will break off and may crack bricks) but when holding light pressure works great. Haven't had need to push the hole size drilled over 1 3/4" and haven't needed to core drill any big holes but I am sure it wouldn't have too much trouble there either. For it's size and power, it is not a heavy tool-but be warned that this is a heavy duty tool so it does weigh about 20+lbs with bit loaded. Case is huge-think your standard drill plastic molded case on steroids-but it does the job protecting your investment in this tool. I also like that it comes with a couple handles so you can mix and match what you need depending on the job. The torque limiting and anti-vibe features make it usable by even relative novices-you won't get cracked in leg or come close to breaking a wrist with these features (although I would still familiarize yourself with this tool and its power before using it for anything you don't want to accidentally pulverize as it may get away from you). Overall very happy with this beast.
