Will the HF MF-Tool cut a concrete paver?

[radhak]

I just need to cut one (single) paver into half : the thickness is 2.5" and 4" wide. I am wondering if this is the excuse I need to buy the HF Multi-function tool. Does it have a blade that would help cut a paver?

I tried cutting it with a hacksaw but I'd grow old before I get thru. Also tried a chisel but only managed to chip off at the point of impact.

I am guessing I could also buy a blade for my circular saw that does the job?

You probably "can" with the grout removing blade but it would take forever, IMO. For things like that I would get a hand held air hammer and chisel set. Click here for HF Air Hammers. Those things make quick work of that kind of concrete, again IMO.

My mom's house (now mine) had a tiled shower built over concrete/wire mesh walls (built in the '50's). It developed a serious crack. Back in '96, two estimates were in the neighborhood of $2000 just to remove the tile and concrete. The shower was custom built and 36 inches by 36 inches, 3 sides and bottom.

For $250.00, I bought a portable air compressor, air hammer and tools and had the whole thing out in one day, including having it hauled off. That was some old, hard concrete with average thickness of 2 1/2 inches.

IF you only want to cut a few, a concrete blade on a saw should do it. Get a mask though!

drill a series of holes with a 1/4" masonry bit - every half inch and then whack it with a chisel right between two holes near the center. Or crack it like an egg across a hard, sharp ridge. Hopefully it will split along the line of holes.

Might work - the paver i'm guessing is $2-5 and masonry bit if you don't have one is a couple of bucks. If it works it will be the cheapest, reasonably fast solution. If not you're out one brick and a bit.

Got a Ginsu knife??

If you don't need a smooth cut, just score a line, both sides, with a chisel or masons hammer, then use the chisel side of the masons hammer to knock the cut off, did many concrete blocks like that.

I need to cut just that one paver for now. The air-hammer is interesting, but I already have masonry bits and a hammer-drill, so I guess Loring's suggestion is nearest 'at hand' - and maybe the same principle as the air-hammer?

I tried the scoring/knocking part, but only see chips fly..

Ginsu knife....hmmm; maybe a Hattori Hanzu sword...?

Ive cut a bunch of concrete with my circular saw and an abrasive blade.

My thoughts too....diamond or carberundeum blade will work well and leave a pretty good cut.

A hammer drill and an air hammer are not even close. When you try one of those air hammers, FEEL THE POWER! It kinda gives you ENERGY! You WANT to Attack the concrete . . . for about 10 minutes until vibes and dust get to you! But it does give a feeling of POWER! Just KNOWING how much damage you can do it a couple of minutes is FUN! Not quite as good as dynamite, but still fun!

Hey! He's looking for an excuse to buy a new tool!

Go ahead. Use the MF tool to score the paver deep on on both sides, then use the air-chisel, that you also bought, to complete the cut.

Should work great. (I've owned a Fein MF tool for 7 years and use it almost daily in my handyman business.) I only regret the $300+ that I paid.

You shouldn't regret it... That's why you been able to use it daily for 7 years.

I just realized that I have had my Fein for 13 years - and most of the time it is at the wrong house (USA.) I have had it here (Japan) a couple of times. I got my $250 worth out of it the first month I bought it.

Sure wish I had a HF clone over here right now.

See, Hank? You're adding years to the life of you Fein by not having it where you can use it...

You're right! I've actually made more money because of that tool.

I've thought of buying an HF unit so I don't wear out the Fein, but the Fein will outlast me by many years. (My grandson has asked me what I'm going to do with my tools when I die ) He's 12 and he didn't mean it to sound so weird. Just caught me off guard.

The 12 year old is going to be a good woodworker. His 5 year old brother is a major motor-head, so he'll probably get the '59 Bugeye Sprite.

No votes for a nice shiny new angle grinder? Ok, 1 vote. I use this thing all the time for rough work and heavy duty sanding. Mostly, the wheels and other accessories are real cheap to buy.
