Powerful use Bosch SDS Max bits

I had to dig a trench 120 feet and in some places it was over 5 ft deep and I began to hit boulders.I called a local and asked him if a skid steer and a jack attachment would break them up.I was told, you have to dig them out, it would be a waste of time to try and break them up.Challenge accepted.This Bosch RH540M 1-9/16 Inch SDS-Max Combination Rotary Hammer with 5/8 inch and 3/4 Hammer Bit drilled into the boulders and then I split them with some 3/4 Feather and Wedges, those thing are amazing.I also used a Bosch Clay Spade and Chisel Set on the impacted clay.It took about two weeks and it was a lot of work but the drill, bits and spade never let me down and I got the job done and saved a bunch of money not hiring someone with heavy equipment to remove the stones.

Meet the Mini Jackhammer

This Bosch tool is a beast, and I mean that in the most flattering of terms. When I first removed it from the box and hefted it I thought, this thing is heavy and big, and operating it is gonna be very difficult, and tiring. Thankfully my assessment was way off. I simply inserted the 3” chisel bit, placed it strategically on the surface I was working on, and IT did the work, ripping up large slabs of backer board, tile included!! It made what I thought would be a long and arduous project into a 1 day deal. It’s the best power tool I’ve ever used. Period.

Not for “Light Duty” use - (Helpful Factoid)

If you are planning on using this sporadically for light duty tasks then a word of caution. Bosch uses a thick grease in this model that needs to be heated up with moderately long use times to properly lube the inner mechanical workings of this tool. If you are a DIY’er or someone who only plans to use this rotary hammer for short bursts of work, then the grease may never get up to the temperature needed to keep things oiled. This can easily lead to premature failure. One potential fix is to open up the case and replace the thick grease with a more viscous Bosch grease or oil. However it might be better for you to just buy a different model. This is the only SDS Max Bosch Rotary Hammer that I’m aware of which uses this thicker type grease that requires hotter internal temperatures to work properly. The next bigger models up the line use a much more viscous grease/oil which prevents this problem.This isn’t a well known fact so I’m hoping this review helps those that can benefit from it.

Amazed

Loving it

I just started using this tool and I am glad I chose it. I will be using it mostly for digging in hard soil. It’s a little heavier than previous hammers I have used but that’s a good thing with more power. Two thumbs up so far.

Way powerful machine.

Actually its WAY more power than what I need it for, but since when is having too many and too powerful a tool in your basement a bad thing? My wife says as long as I use something she doesn't care what I get. So that must mean if I only use it once its ok. :)I really only needed a machine to put 5 screws into our basement wall so yeah a regular hammer drill was the most appropriate, but . . . now if I ever need to make a 5 in hole in the concrete wall, I can. Plus it gave me an excuse to buy the spade chisel, sds-plus adapter, ground rod driver, 3 in scaling chisel . . . you know, just in case . . .
