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…

This tool is smoother than I was expecting it to be. It is well balanced and easy to use. It carves concrete into powder (with the chisel bit) rather than blowing things up into shrapnel like I initially assumed it would. Great tool!

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.

Dont tell my wife! Best tool ever! Performs better than expected. Used it to dig into hard clay and concrete.

Already had a Bosch Bull Dog but needed to have the ability to drill bigger holes without going to a spline bit. Bought the SDS Plus adapter so I can use the smaller bit’s with this drill without having both drills out at the same time.

Great purchase.

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.
