I don’t think I have ever come across a situation where I wished I had a right angle plunge-cutting oscillating multi-tool blade. But now that I know such an OMT accessory exists, I can think of some places where it might come in handy, such as when vertical clearance is tight.
The Imperial Blades IBOA391 bi-metal 90° multi-tool blade features a 2″ blade width, 18 TPI, and 1″ max cutting depth.

Imperial Blades’ One Fit accessory mount works with most brands’ oscillating multi-tools. As with their other OMT blades, it’s made in the USA.
There’s only one review of the new blade on Amazon so far, with the user complaining that the length of the blade is shorter than the 2″ Imperial Blades claims. Since the 2″ blade width is mentioned on Imperial Blades’ website and all retailers’ pages, we’re not sure what to think.

Apparently, this model, IBOA391, replaces the MM391 (via Amazon), which has mostly positive reviews on Amazon. The only difference seems to be the slightly different mounting interface, with the new model’s open design fitting a wider range of tools (including Dewalt’s!).
Can you think of any specific applications where such a 90° oscillating multi-tool blade style will be useful?

Amazon has them with “free shipping” included in the price.
ToolsPlus has them for $15.96 and the older one in 3 inch width for $17.56 – but you’ll have to bundle it with other stuff to qualify for free shipping (orders of $50 and over)

Hmmm… I’m wondering how well this is going to work, since the axis of rotation on the multitool is no longer going to provide a flat cut. This right angle adapter will produce a 3° arc along the length of the 2″ blade, and I wonder if binding will be an issue with plunge cuts or cuts in wide materials. Although now that I think about it, a 1″ radius at 3° is only 0.05″, so it may work OK after all.
Stuart
I didn’t even think about that!
Perhaps the blade is curved ever so slightly to avoid the potential for binding? Or it might just remove a little extra material from the ends of the cut?

It was MY first thought as well, actually. But, instead of thinking it was a bad thing, I was thinking “Wouldn’t that make it easier to make curved cuts, like an arc, or circle?” You know, for those times when you may be cutting into something that doesn’t cut a cornered edge very well?
I think it might be a decent way to score arcs through a laminate, or some sort of…I’m sorry the word is escaping me right now…( Plywood/MDF with a laminated faux-wood texture on top.)

This was my first thought. Seems like it would just frustrate me. OMT already accomodate plunge and flush cutting pretty well I think.

I know this thread is old but I tried this today by bending a blade. It did not cut at all. So if this does work theres something different about it.

Why are all these oscillating tool blade so dang pricey?? When I bought my rockwell tool I think I spent about 50 bucks ( on sale and had a 10%coupon ) came with a few blades, finally after a years worth use ( not too heavy use ) I need new blades
Went to lowes to check out prices and for a 3 pack of standard use multi pack was 35 bucks for 3 blades, only brands were bosch and dewalt on the shelves. went on line and I reckon I will have to order what I need.
At the time i bought the tool I should have picked up extras but just didnt think about it and they were cheap i could have remembered that a 3 pack of blades were around 10-12 bucks!
This blade looks neat and would work for those hard to reach areas
Stuart
Better blades cost more, but deliver great results. Shopping around or buying multiple blade packs can save a bit of money sometimes.

Over the early multi-tool years, I got used to shelling out for Fein blades (made in in Germany or Lichtenstein) – so current prices seem less expensive to me. I’ve been using Bosch blades (Swiss made), and Imperial Blades (USA made) – that seem to be high quality and last long enough. I’m not sure if other blades like Dremel (Taiwan ?) or Dewalt (China?) are any cheaper and/or of lesser quality – but I’m betting you can find some cheap blades at Harbor Freight – quality and longevity unknown

There have been a couple of times when a rt. angle blade would have helped, but not very many times. Years ago, when Imperial first started marketing blades, I spoke with one of their people re. blades that would be nice to have. One that I was hoping to see but never came about was a blade that is shaped something like a ’rounded-edge’ Christmas tree, w/serrations on each of the sides of the tree. Wouldn’t come to an exact point on the end (too brittle), but could taper down enough to make delicate cuts, or plunge cuts. I may just weld one up and grind my own teeth…….
Before there was Imperial Blade, this was the man for Fein blades: http://www.multiblades.com/multimasterblades.html
Imperials are awesome blades and I sometime use them; I prefer the multiblades. Don’t know if he’s still in business, but his website is still going.

That would be a ‘flat’ Christmas tree- 2-dimensional, not 3.

EBay is the way to go, I got 25 blades for $12, yes $12. Others for $1.

This might have been handy the other day when I wanted to shorten my sewer clean out pipe (6” schedule 40 pvc) it was sticking a couple feet up above ground level. I cut it closer to flush with the ground so I can straddle the mower over them.
To cut a somewhat square/level cut I had to dig out alot of dirt to make room to accommodate the length of my oscillating tool+blade and then make several blade angle adjustments to complete the cuts on both pipes.
With their blade above I could probably almost leave the shovel on the hook and cut the pvc from the inside out
It would also be handy to make a flush cut on pipes in the floor or in walls that are in a corner ( saw zall blade tip might strike the adjacent wall ruining blade).
Same working under cabinets with plumbing sometimes you need more room to clear a saw zall in tight spaces as you work parallel to the thing your cutting. This blade would allow you to work the oscillation tool perpendicular to the wall.

You should out one of these next time you need to cut pipe flush or below a surface.

Cheaper than an oscillating blade too!

I have wished for a blade like this when making a pocket for a structural beam to sit in in remodeling. We basically had to cut a big mortise perpendicular to the ground. This was just what I needed to cut the bottom free. Maybe hard to explain…
I never considered the arc though. It doesn’t seem like there is enough arc to bind the blade to me. Though it is hard to tell.

This is my situation. Trying to plunge a blind, square hole for a 4 x 4 into a stump. I can drill a series of round holes and chisel the edges square but I still have to cut out the long strips I’ve chiseled.

Trying to clear some small spots of cement (about 2mm-4mm thick) stuck to the inside of a galvanized steel railing due to construction failure (they probably didn’t protect that area and a bit of concrete poured in) and now the window won’t close because the rails are dirty and won’t let the wheels go through.
Clearance is very tight, hence I googled for a 90 Deg. solution ..
Will such a blade be able to scrap and remove that bit of concrete?
say a 1-inch by 1/2 inch strip of concrete that is about 2-4 mm (8th of an inch?) above the metal surface.
Don’t care too much about the longevity of the blade as long as this one-time task is complete …
never owned a multi-tool but this problem might make me a proud owner ..
any thought?

Late to the party (discussion) here but I’ve been using this blade to cut the nails between floor joists and subfloor. Joists were built over spanned so we cut them shorter, added a beam up into the joist cavity & used hangers. 23 joists with lots of tight spots around electrical, plumbing, mechanical and other structure. No other tool I know of could make those flush cuts of nails.

From a roofers perspective- I want to order this blade and test it for roofing/siding. In my mind, if this blade comes with a carbide tip, it could be very effective in cutting siding nails that prevent roofers from being able to properly install new sidewall flashing in retrofit re-roof situations. If this blade could be used to cut the siding nails that are within 3-4 inches parallel with the roof line, then it could be very useful. You would need to first cut the existing siding off the roof 1-inch or so, which would allow the blade to get further up under the siding and reach obstructing nails. We find most houses have the siding tight to the roof plane in our area, so we have to cut the existing siding back off roof parallel to the roof plane.
