1-1/4 Inch SDS-Plus 13 Amp Heavy Duty Rotary Hammer Drill with Safety Clutch 4 Functions and Variable Speed, Including Chisels and Drill Bits

I had the small Bauer hammer drill and it was fine for most drilling work I have thrown at it but wasn't cutting it for light demo work. I was ready to get its bigger brother but they didn't have any at the first store I tried near closing time (despite the website saying they did). I looked on Amazon and this one was bigger and had its own bits for less money and I could get it first thing the next morning. I was a bit hesitant but after getting it and putting it to work this thing was a beast. The grease is replaceable and it came with a tool like a grinder wrench to open it. I did add some because I worked it pretty hard but it never complained. The Bauer one I have leaked grease profusely with way less abuse and its not serviceable. It did the job I wanted and the bits held up better than the cheap ones I had bought before but not as well as the Bosch ones I had. Overall if you have some drilling or light demo needs this more than did the job for me and I was pleasantly surprised with the overall quality it was an amazing find even with the odd name and color scheme. For reference I used it to break up 3 large concrete lumps that were once around some long gone wooden posts near my front porch. It was several hours of hammering to break them up to my satisfaction so I could park there. Sure a full size jack hammer would have finished the job much faster than waiting for one to get here and I really don't have a need for one and this was better than renting one as I have a solid hammer drill for future use.

Cost was the same as an 8 hour rental. Figured it would work ok but not great. When I used this demo hammer it was AWESOME! We destroyed a tile shower, tile floor and 2” concrete slab in a bathroom in 3 hours including haul out of debris. This tool has PLENTY of power, tool bits were good quality, I did buy spares but never opened them. The handle absorbs the vibration, bit holder works well, easy to use, can’t say enough good things about this tool and the price was amazing.

Bought this for small bathroom job. Works well. Does get hot when constant use. But did the job of taking tile up from a cement bed. Heavy duty easy to operate and great price

UPDATE: At the bottom of the review I noted that there were no instructions about how to replace the motor brushes, even though a spare set came with the drill. In response to a question about that the company rep said they'd "try" to get the instructions from their engineers. I was skeptical that I'd get a final response. To my pleasant surprise they did! And so I've now bumped my rating from 4 to 5 stars. I had to drill several holes in concrete, and since I don’t anticipate having to do that a lot more I took a leap of faith and bought this product — one of the lowest price hammer drills I found on Amazon. For my purpose I was not disappointed at all. The entire package of things that came in addition to the hammer drill itself consisted of a variety of bits, some extra grease (needed to keep the drill in good shape), a rod to help limit depth of drilling, and a set of extra brushes, all in one nice, organized hard plastic box. I first tried drilling my holes with an old corded Craftsman drill (one that looked like most drills) that had a hammer function, and used Bosch bits made for concrete. Got basically nowhere after MANY minutes of trying: barely an inch into the concrete. When I got this hammer drill, and after reading the instructions, I put in one of the inexpensive-looking bits that came with the tool, not really expecting much, and started making my holes. I was more than pleasantly surprised. The tool and the bit made short work of drilling a pilot hole through about 5 inches of concrete, and following up with another supplied and larger bit gave me a nice, perfectly sized hole. One slight negative: Adding grease periodically is necessary to keep the drill working. The tube of grease that came with the tool wasn’t labeled to indicate what type of grease to buy when the supplied stuff ran out. I contacted the company (their email address is in the manual) and after a few days got a reply: basically any grease made to lube SDS drills (e.g., Bosch SDS drill grease), which this drill is. Readily available and inexpensive. So I’m cool with that. I gave only 4 stars, however, for the following reason. A set of extra motor brushes came with the drill, and that immediately suggested to me that the installed brushes (and so the drill) aren’t going to last a long time. I do not know that for a fact, however, and I will not be using the drill often so that may not be a problem for me. UPDATED: See beginning of review. I contacted the company by email about this too, and after a few days the person who replied didn’t know what motor specific brushes would be needed in case the ones supplied went bad, and they don’t know where to get another set. They also said there are no instructions about how to replace the brushes and the engineers who might know any of the above are “on vacation.” So, even if the installed set of brushes went bad the provided replacement set may not be worth anything if you can’t figure out how to replace them. (There ARE YouTube videos, but the how-tos seem to vary from brand to brand). Unlike some tools with an electric motor, there is no external cap to unscrew to just slide the old brushes out and put the new ones in.) One final note: The chuck does NOT take regular twist drill bits: you need to use "SDS" bits, which have a different shank that is best for heavy drilling. You can Google SDS drills (and bits) for more info; the bits themselves are readily available, and that's what most good concrete bits are. OVERALL: If you aren’t going to be doing the amount of concrete or other heavy drilling that a typical contractor might do, this is a great product at a great price, and I HIGHLY RECOMMEND IT.

I bought this to cut a hole in my 100 yr old concrete basement floor to install a sump pump. A saw would had been to messy in the basement or I would had borrowed one. I looked into renting tools to cut the floor, but the cost would had been 3x as much as buying this hammer drill. Is this tool designed to jackhammer through a 100 yr old 6" concrete floor? no. Did it? yes. I worked on it a little at a time, bust for a while, then clean out my loose so the drill could cool. I cut a 3x3' square hole in the floor in maybe 2 hours, I was not in a hurry. the hardest part was getting the hole started, then after that it was just time. The drill came with greased, but I added more to be sure (came with) The drill does get hot if you use for long period of time and some grease will get on the end of the bit. But the little drill worked just fine, hammering away. I figured if this tool lasts for the sump pump, I still came out to the better then renting. But since cutting the floor, I have used it to drill a few holes in a concrete wall. This summer I will use it to bust up the old block wall and brick stairs to my basement on the outside to rebuild and may use it on the poured back porch steps. They are much thicker, so I am not sure if the tool is large enough to take that on, but we will see. I am happy with my hammer drill and for a small hammer job, cleaning up or drilling I think this tool would suit anyone. To use as a commercial jackhammer, no it will not handle that, buy the correct tool for the job. But for handy people or home owners, I think it would be a good buy.
