Fein MultiMaster FMM 250Q Top

I saw an installer using one of these and was impressed, so I bought one.
I find it very convenient for some jobs. I used it to cut 6x10" holes in wallboard for mounting speakers in a room's walls, and then discovered some framing wood that was too close to the holes. By mounting an E-cut blade at 90 degrees one side or the other, I was able to cut half way through a 2x4, one inch outside the hole area, to make the needed clearance. Without this tool I'd have had to saw right through the wallboard, weakening it a lot, then patching the cut. Even with this tool, being inexperienced, I did cut into the back of the wallboard in a couple spots, but it was easily patched and not weakened too much.
In another place I cut about 3/8 by 3/8 by 2" out of 2x4 right behind the wallboard. This could have been done with a chisel, but it would have been more time consuming.
One does have to be careful not to burn the work--you can put a lot of power into a small place and easily scorch wood and make a lot of smoke, and presumably fire too...
The tool is very comfortable to use, because it is not fighting to go somewhere, like rotating cutters do.
My only complaint is that the blades cost 2-3x more than I think they should. There are some much less expensive similar tools just coming out now, and perhaps the competition will lower prices, but of course the other tools aren't going to use compatible blades I'm sure. And likely they won't be as sturdy as this/these.
One job that failed: a number of sheetrock screws protruded maybe 1/16" into a closet, just waiting to snag someone. I tried to cut the tips off using the wood/metal E-cut blade, but it damaged the blade (though I was still able to use it for the above mentioned cuts). The carbide tile file was too coarse for the job. I finally used a Dremel with a cutoff wheel instead. Maybe the diamond blade would have worked.
All in all, it seems like a good addition to a remodeler's toolkit.Get more detail about Fein MultiMaster FMM 250Q Top.
