I was actually commenting to someone that they should make 90 degree bend oscillating tool blades and low-and-behold these appeared for me to review. These blades are perfect to getting into tight spaces because the length of the multitool itself won't fit.

Overall the blades seem well-made and sharp. They definitely are more of the standard type blade and not carbide quality – so they are definitely going to wear out if you are not careful using them. They are definitely a good value as you get a half dozen blades which should keep you going for a while. You are only going to use these in special situations and not for your general purpose work, so a set should last a long time.

These are a great addition to my toolbox.

This blade set has turned out to be very useful for general DIY work, especially in awkward spots where a standard straight multi tool blade just will not reach. The 90 degree blades are the real stars; they made it possible to cut in tight corners around outlets, door frames, and cramped areas where I would have otherwise been stuck. For typical home projects, they have become my default blades more often than I expected.

Cutting performance is solid for the price. I have used them on drywall, softwood, pine blocks, PVC, and even some wood with nails, and the bimetal blades have held up better than I thought they would. They are not the most aggressive or fastest cutters out there, but that actually helps for controlled, detail oriented work where you do not want to overshoot or chip up the surrounding material. For trimming, notching, and careful cuts, they do the job consistently.

The main thing to understand is the flex. Because of the length and the elbow shape of the 90 degree blades, they have a bit of give, so you cannot muscle them through material. You really have to let the oscillating tool do the work and guide them with a light hand, or the cut can wander a little. Used with patience and proper alignment, they cut acceptably clean; forced too hard, they feel less precise. Compatibility has been good with my tools, thanks to the included adapters, which snap on securely and have worked fine with both my DeWalt and Dremel style multi tools.

Overall, this is not a “pro demolition” blade set, but it is a very handy, good value option to keep on hand for typical home repairs, pinewood derby level projects, and tight access cuts. When you are in a bind and need that 90 degree reach, you will be glad to have them in the bag.

Pros:
90 degree blades reach tight, “impossible” spots regular blades cannot
Bimetal blades handle wood, drywall, PVC, and even some nails reasonably well
Universal style adapters work with common oscillating tools
Good control for detail work rather than overly aggressive cutting
Useful variety for everyday DIY repairs and small projects

Cons:
90 degree blades have noticeable flex and require a lighter touch to keep cuts straight
Not the fastest or cleanest option for heavy, precision cabinet grade work

I ordered these primarily because I've never seen L-shaped oscillating saw blades before, and I thought they would be useful. I'm sure they're not new, I just never ran across them for whatever reason.

I've also never heard of "Japanese tooth" blades, but it's a real thing. Maybe I don't get out enough. Look it up if you're curious.

These blades fit my older Porter-Cable oscillating saw, which is still going strong after at least 15 years. However, the opening is a bit too small and it takes some effort to get it on the tool's shaft. This isn't the fault of the tool; I've used many "universal" fit oscillating saw blades over the years from lots of manufacturers and they all fit just fine without forcing them on.

If I hold the attachment end of one of these next to another manufacturer's blade, the opening on these are very slightly smaller.

I have a project I will be doing in the near future where I can use some of these blades. If I come across anything negative, I'll update this review.

Given the price of blades at retail, this is a pretty good value if only the openings were sized correctly.

These oscillating saw blades have been used on several small cutting jobs over the past few days. They attach securely and feel well balanced once fitted. Cutting performance is smooth and controlled, especially in corners and tight spaces. The blades handle different materials without struggling. Teeth remain sharp after repeated use. There’s minimal vibration during operation, which improves accuracy. Switching between blades is quick and straightforward. After multiple tasks, they still perform consistently. They’re useful additions for detailed cutting work.
