Oscillating tool blades for drywall

[pugglewuggle]

I just bought a Milwaukee M18 oscillating multi tool. It comes with a wood blade. I cut some wood with it and it works great! Question is: can I use the wood blade on drywall or will it screw up the blade? Should I buy a drywall specific blade? Is there any advantage to a drywall specific blade if the wood blade will work? (Just to be clear, I’m sure it will cut it for a while but I don’t want to burn up the blade if I don’t have to)

Thanks!

works fine for plunge cuts
Drywall dulls everything,after all its sheetrock

works fine. there are drywall specific blades that look like a hacksaw blade, semi circular, but drywall will dull all blades .

Agree ^ All blades work, but like with all sawblades, better blades, like e.g. Bosch, last longer than cheaper blades. And using specific blades for drywall, or metal &c, saves your wood blades from dulling early.

you're in michigan. you most likely have a menards down the street. buy a bunch of blades, they're cheap, plus, the 11% sale is still on

Best dry wall blade is when those wood or “metal” blades are worn out. When the drywall completely smooth out the toothed , it makes the best caulking scraper. I don’t know what after this. Have not worn our the caulking scraper yet. Maybe Amir will become a lock pick

My favorite drywall blade is a worn out blade that I cut new teeth into. Just use a cutoff grinding blade to make a crenelated (like the top of a castle) edge. Anything dull and coarse will work great on drywall. Big triangles, squares like you find on a thinset trowel.

I bought some scraper blades years ago. Haven’t worn them out yet.

I use the Japanese style oscillating blades with the sharp teeth like those used on a Japanese saw. They zoom right through the drywall.

I saw that kit sale with 1.5ah battery.

That seems low for M18 batts. I'll have 5 and 8 for backup.

Will the 1.5ah be useful?

When sharp, those make fantastic wood trim cutting blades. I wouldn’t dull mine on drywall, but I do recycle them.

1.5 is pretty small for a tool like this that uses a lot of power

I thought about welding a sections of all band saw blade to revive the life. Have all the materials including eBay coils of extra wide 1-1/2 width blades. Just gave no time or need. Yet. Well they do say necessarily is mother of inventions. Unfortunately I don’t have the need.

Years ago, I welded a section of a carbide tipped sawzall demolition blade to one, do make something that wouldn’t dull on my plaster walls. It works great, but now that you can buy them, it’s not worth the effort to make.

Any OMT blade will cut drywall, I keep a couple of old worn out wood blades and use them for drywall so I don't ruin a good blade.

I just use my worn out blades and I have plenty of those. As soon as a new blade sees drywall, it's useless for anything else. As long as there are teeth, they will cut sheetrock though.

That's exactly what I did and it works great.

I used a drywall blade and found that it wears out just as fast. I think I hot maybe 20 feet of drywall cutting out of a blade before it dulled.

For this reason, I find using and oscillating tool for drywall less than ideal, unless it is some specific application need (which I have not found yet), where a regular saw would not work.
