OMT blade to bevel installed tile?

[stickshift]

I need to bevel the edge of some installed floor tile. Access is limited, so I can't get my 4-1/2" angle grinder in there, but I can get my OMT in there. What oscillating tool blade would be good for this? Diamond grit blade is supposedly good for grout, but no idea if that will work for tile.

Entirely depends on the tile.

I’ve used the carbide sanding plates to remove adhesive/thinset as well as the carbide cutting blades to remove grout, works like a charm. But: None of these would even scratch the back (not glazed) or sides of the tile once the adhesive/thinset or grout was gone.

Potential glazing will be an issue on its own.

Most of them would also be too coarse, and have you ‘jumping’ over the tile and then probably disintegrating because the force applied is too much for those single carbide bits. It’s going to be tedious and highly likely you will go through quite some of the plates.

If I was to try this, I’d go with one of the highest grits available. Remember that most of these are designed for a max. speed between setting 2 and 3.

Diamond sanding plates exist in natural stone / terrazzo repair/maintenance. Mostly designed for use with delta sanders, not necessarily with multitools and their sanding plates. If it’s really worth a try again depends on the tile and price vs. quality of the plates. …

What I would probably do, if you can fit the multitool in there, you can probably fit one of those small cordless straight grinders (and/or rotary tools) in there as well that are available today. And then get a diamond grinding pin for it. Obviously check that it fits the requirements (top speed, shank diameter, lateral force being applied to it, (…))

If you have a diamond tooling specialist in your area, inquire with them. Sometimes flooring/tile dealers sell diamond tools as well and might be able to offer some helpful advise.

Hope this helps.

Kind regards,
Olli

You don't say what kind of tile, ceramic, porcelain, granite, marble, etc. and you also didn't say how much of it. A picture of the situation and why you need to bevel it would really help.

Ceramic tile. Dishwasher is in the hole, so to speak, created by tile that was installed on the kitchen floor, but not under the cabinets, including the dishwasher cabinet space. Need to get dishwasher out non-destructively. It's pretty close, and I think putting a bevel on the tile will allow me to clear the tile. Countertop is very heavy and has a backsplash, so lifting that seems like more work. Dishwasher's feet are fully retracted, front and back.

Will the dishwasher's trim cover the bevel when you put it back in? Just wondering how nice the cut has to look? Or if it has to be a bevel or if you could do a normal 90 degree cut where you would start the bevel? The m12 cut off tool comes with a tile blade. I don't have mine with me at the moment to see if it would fit under the dishwasher door or not. https://www.homedepot.com/pep/Milwa...eaGo8FQ-u9BoCMIAQAvD_BwE&gclsrc=aw.ds#overlay

Another option is a rotozip tool with a diamond bit. Another option might be a toe kick saw with a diamond blade. I don't remember if I tried ceramic tile with my OMT or not. I know I bought a few diamond blades for it and tried cutting in some tile and it sucked. But don't remember what type of material I was cutting into. I do remember it burned the blade up pretty quick and the blade was an expensive one.

beveling ceramic tile will look awful. once you're thru the colour coat you're into the base which will not look the same as the tile

I had this problem as well. Problem was trying to lift and pull, as I hade barely enough clearance. I slid a thin piece of plywood underneath to remove the lift aspect, and finally wiggled it out. If you can cut the levelers off to remove it, give yourself space to work when cutting the tile, might make life easier in the long run. I was close to doing that.

I hate people who don’t plan ahead. My first tile job I pulled the dishwasher and stove out. The one who did the most recent in this house left both the dishwasher and bar fridge in place. bastards

Indeed. After dealing with this, I will never put down a floor around appliances.

Damn it, replying here cursed me. My bar fridge melted down, overflowed the catch bin, and flooded the floor, swelling my plywood.

Could not lift and pull at all, think the insulation swelled a bit. Put two C clamps on the sheet metal frame, and hooked the ends of my truck tow strap to each clamp, and putty knives under the feet, overlapping the tile. Gave me a nice handle to lift and pull at the same time, 1/4” of wiggle per side, then 1/2” etc. came out easily. Used Cincinnati clamps with small pads to avoid bending the frame.

I’ve used a diamond grit oscillating blade for grout and it worked pretty well on tile edges too, though it’s slow going. For beveling, a carbide grit blade might be better if you want a smoother finish without too much dust. Just go slow and keep the tool steady since access is tight. Worth testing on a scrap piece first.

I have a diamond grit OMT blade for grout and it did barely anything. Tried carbide blade, and that was too slow. What I ended up using was a Dremel cutting disc, which worked well, which I suppose isn't surprising as it's essentially a micro angle grinder. Took me 4 discs to cut 26" of tile. A 3" cutoff tool would have been much faster, but wouldn't fit in such a tight space.
