If you let this tool’s weight work for you it is a very agreeable product. Adjustable handle for control/stability makes horizontal work a breeze. All in all like it so far.

I have been using this product for the past month or so doing with it whatever it’s capable of doing. I purchased a 8 bits for it to do various tasks and to test it’s limits. I first used a Bosch clay spade to help with the hard clay and shale in the bottom of post hole footings and needed to use a point bit but it worked wonders in assisting to dig the hole to the required depth. I have needed to rely on a digging iron in the past and they just tear up your hands and wear you out quickly throwing a 40lb tool into a hole to break up the earth. Now my hands feel great with the exception of the shakes you have from jittering a tool for long periods on hammer mode. The tool has the power to do quite a lot and the pros and cons I personally discovered are as follows:Pros:The tool is of a superior build quality and has the power you should expect from the brand and the price. It has all functions you should expect for a tool in this price range. It feels like a quality tool with quite a bit of heft and though heavy, it initially feels comfortable in your hands. When using the tool vertical, in most cases, the weight of the tool is enough to load the bit as well while you simply just hold the tool instead of using weight packs to assist which helps to not wear the user out so quickly. The chuck is simple to use and tight around the bit to prevent much debris from entering into the chuck. Also, the selector switch is tight and switches with a bit of force and should not easily be forced out of selection while doing tasks.Cons:I would have liked a slightly longer cord but that’s a bit picky. No other major cons except for weight, which is a PRO specifically for using this tool without applying your own force. Apart from the tool specifically, the bit are expensive and I wish some longer lengths were available without the need of an extension which is also an added expense when you need it.I highly recommend this product for many of the heavy duty tasks as breaking through a CMU wall, concrete floor, digging tough earth and many, many more reasons. With that, I strongly urge you to research the bits prior to completely committing to this tool so you understand the expense that comes with it in order to completely use it to its fullest potential.

The 120-Volt 1-9/16 in. SDS-Max Rotary Hammer is a wonderful tool to own. It does not come with any bits and they are kind of expensive. We chose a spade bit for our first use. Our ground is so hard that it is impossible to dig in. This tool made it look like butter. We will have some concrete work to do at some point in the near future and this will come in really handy. It has variable speeds and can be switched between rotary/hammer and just hammer. It’s very easy to change the bits. It is a little heavy for a woman (at least for me) but my husband loves it. It also comes in a very nice case to keep it protected when not in use. It probably is more for the professional but we love it for our DIY homeowner needs.
