I have a 4" concrete slab that's 6'x10'. Is this powerful enough to break it up?

Absolutely. I have used it to break up 150 linear feet of concrete footing that ranges from 3" to 6" thick. My personal preference is to use the flat bit, not the pointed bit.

It would be good to do a test with a couple of small pieces of hypertufa, one with and one without. I loosely measure out a couple of tablespoons of fibers from the bag for each 10 pound bag of concrete. Once they're separated, there are a lot of strands. Wear a mask when pulling the fibers apart. They do strengthen the concrete permanently.

No way! It only works 50% of the time. I would definitely not trusted before breaking up concrete.

Sure you can! But you are limited on the thickness of the metal !!! I'll recommend 1/16 or less! Take you time!Absolutely no "concrete"

If the ground is broken it will eventually work down about 6". Unbroken ground takes a little more work! Eventually will get to that point but a lot more work! It works very well all around though!

I used it to dry cut pavers and termite block. Anything over 4 inches thick is pushing the limits of the blade.

Using this drill with concrete drill bits would work for small projects. Heavy drilling should be done with a larger and heavier duty drill.

Whether target concrete is raised as a step or slab excavation, drilling and chiseling will get the job done. My following note addresses slab excavation. By drilling an outline of area to be removed - say 1" to 2" apart using a smallish ( I used 1/2" SDS ) drill bit - your concrete will crumble when hammered with a chisel bit - I used 3/4" wide Viper chisel ). Removal of about .5 sq.foot took maybe 1/2 hr. You are removing about 3 times as much material but I'm sure you will excavate at a faster rate as you learn how your tool operates. Apart from perforating the concrete ( avoids cracks outside removal zone ), a sledge hammer helps greatly when broken concrete lumps lock up on each other. Good Luck !

definitely not. You need a hammer drill and hammer drill drill bits for concrete drilling

Yes, I have a curbing company and I use one like this on my 7 1/4" circular saw to cut 4"x6" concrete curbing.

I believe it will. Not as quickly as one of those huge and heavy ones used in road works etc. but I have no doubt that it can do it. I've used it on concrete up to 4 or 5 inches thick and it can do that easily.

No. I have one of these to fluff and spread my 3/4" rock driveway and it does a killer job. Makes it look like new but it won't do the job on anything bigger as you are trying to do

Absolutely! This is a great P.H. digger. I made exra wide 4' deep holes and set 6" dia. concrete pads at the bottom, to set 4"x4" posts on.

No, this is for resistant , brittle material , Tile , thinset, but will gouge the concrete. The equipment you need are specialty grinders, the adhesive has gotten into the pores of concrete, to be done properly a thin layer of surface must be removed.

The grout mixer is very heavy duty and works extremely well. The real issue might be making certain your drill is sturdy enough to handle mixing concrete.

It can do it but if you will be making frequent holes of this caliber i would suggest a Milwaukie hammer drill. But these do everything I need except drill through concrete slabs.

It may work better on concrete rather than wood - which is what I had. However the risk you are running is that you spend a lot of money and time (as I did) only to have to rip the whole stuff up again. I'd try another product if I were you.
