This is an SDS Max Rotary Hammer, which differs from the smaller SDS Plus Rotary Hammer (see my video for a side by side comparison of the bits).This is a heavy tool (14.2 pounds), it has to be to be able to provide a whopping 6.1 ft. lbs of impact energy and deliver 1,200 to 2,750 blows per minute.The tool-free bit changes, and automatic bit locking, make for fast setup and swap out of bits. The bit rotates and locks into 12 different positions, and the variable speed ensures the right speed for the job.The ancillary handle is fully adjustable to any of 360 degrees around the tool.Where using a chisel to lift old tiles, or a drill bit to power through masonry, this bad boy has the power to do it all, and much more.

I have been looking at several new Rotary Hammers for replacing the older ones. I was on a job that the other crews were using Bosch Tools. I tried a couple that was on site and was immediately impressed by the weight, power and variable speed. I could not find a RH540m in any of my suppliers. So after searching HD.com, It finally arrived. I had no idea how big it was compared to what I tried in the field.The next day it was on the job and it’s amazing how powerful and speed of the drilling was. It’s been my best tool replacement purchase.

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.

This is a very good and heavy duty SDS Max hammer drill. Most recently I got to test it for a variety of jobs around my house. I used it to chip out asphalt, to cut paver bricks, and to drill holes in a concrete wall. I have attached a video to show at least one job. The power of this item is very good, with the ability to easily cut through all of the above listed materials. The construction of this tool is very strong as the environment which one would use this is generally not a forgiving work environment. Lots of dirt, and garbage around, and most times one is not treating the tools like babies. Get the job done is the mantra, so the tools can take a hit. This one though, should last for a real long time.The clutch which protects both you and the hammer drill, is not too slippy, but not too strong. It is well adjusted to release only under a fairly hi stuck loading factor (like you forgot to switch to hammer only while using a chisel).Take a look at the video, as this shows its ease of use cutting some pavers. I highly rate this one…

I used a 1 1/4” bit to drill a hole through a 8”concrete wall. Just like drilling thru butter.

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.

actually the $129 masonry bit was defective or missing set screw. so I wasn’t able to use this for the whole job. disappointed I spent near $600 for a job which at this time was useless .
