I install doors and windows quite often, and every once in awhile have a situation where I need to cut a tile floor back to allow for a new door install. I have been using a small grinder with a diamond wheel to make these cuts, but wow what a cloud of dust it makes! Of course, I put up a plastic barrier so I don't get it all over inside the house, but it's still a big mess.
Is there a better way to do this? Also, a grinder won't get all the way into a corner, so am looking for a good solution for that.

Why aren't you cutting the door/jamb?

I have the same messy method, 4″1/2 diamond wheel on a grinder. When I have a door or patio door I try to install them at the same level with the floor so I won't cut it.

Grout blade on the OMT. It is slow but does the job and the dust is easier to control.

You can also get a diamond blade for the omt, I think the grout blades are carbide. Pretty accurate and can get in a corner fairly well

Can you make porcelain tile edge trim from a regular piece of tile that's 12×24? If so how do you round off the edge?

What I'm talking about is an exterior door with threshold installed. Some of the old doors we take out have a thin threshold sitting on the tile, but the new door threshold is about an inch and a half high on the inside.Its possible to set it on top of the tile, but it works out better if it sets down on the subfloor.

I assume you are cutting the tile before you install the new door /patio doors?
They have these bosch shield for grinders that attached to a vacuum, and for the corner you can do what Kurt suggested?Attachments:

They also sell small 4 1/4" wet Circular saws . Puts out a little water to keep dust down .
Always willing to learn .

Our tile installer has used a wheel like this for tile shelves and things like that in showers he has done.

That might be a possibility there. Would you have to do it lightly so you don't break or crack the tile? Where would you find this wheel?

I think the biggest reason that would cause it to crack would be the heat. You can either run water on it as you grind the edge over or just do a little at a time. The process with natural stone is much easier because you can just use sandpaper or the blade of your utility knife.

I have used water successfully. Makes a runny mess, but not a dusty mess. I have used old towels to make an absorbent dam inside the building, and clear any floor mats out of the way and let the water drip/run outside the building.
I used to have a little 9.6v battery operated Makita circular saw with a water bottle, nozzle, and valve attached, but a corded grinder with the right blade works faster.

This is what we want to do as a baseboard with our existing tile thats12x24 and have it cut down. We wanted like a 45 degree chamfering edge on top with the left over tile from doing the floor.

They have them on the list here, I am eventually going to pick one up also.
Let me know what you do, and if you do get it from the list, how many piggies did it go for.April 17, 2018 at 6:57 am #677418

Got it! I was picturing interior doors for some reason.
In that case, I would pick up a dust collection attachment for your grinder (assuming it has on available). With my Bosch, I find that it collects dust from mortar joints very well as long as I don't crank up the speed, so a VS grinder would be very helpful here.
The OMT suggestion that Keegan made above would get you right up to the wall too. Bosch makes both diamond and carbide grit rasps in a teardrop shape that work very well for this. Use the rasp to make a nice score mark through the glazed layer and crack off the tile with a hammer…then clean up the edge with the rasp if necessary.

A wet sponge against the diamond blade helps cut down dust also. To get up tight the OMT with a diamond grit blade suggestion is probably your best bet.

Well I got it done, ended up putting up plastic and taping it to the floor to keep any dust out of the house, then used my grinder with diamond wheel and held my vacuum hose in front of it. Actually worked fairly well, didn't make as much mess as I thought it would. I would like to get the shield that hooks up to a vacuum, I wonder how it is for visibility though? For these kind of cuts I need to have a clear view of my cut line.

when I cut my floor I got a diamond blade for my skilsaw spt 77 and had mama with the shop vac sucking up the dust and that worked pretty good I'm sure it would work with tile also
