Don't know whether these blades are suitable for 'fk5100k' oscillating saw. There are two physical interfaces for various brands of oscillating saws. The universal fit is offered by the Sonic-crafter blades and works well with my Porter Cable brand saw.

Does this fit a Rk5102k?

Yes, this will fit and work with the RK5102K. However, you may have to use the washer (spacer) that comes with it if the blade doesn't provide a tight fit on the tool.

Can rw 9122 blade replaced by the rw8981k?

I am not sure what the blade number references , but if is the same type but with the older close mounting star hole it will with an adapter that you can buy.

Have worx model wa5012 will these fit?

I believe they will with the universal fitment system

Nice set for a great price

This was a great price on Amazon. Love the Sonicrafter and I have heard not all blades hold up well so decided to go with these. They seem to do well and fit my model perfectly.

Can't Beat The Price

My husband bought these for his work. He does construction for a living. He said he gives it a 4 out of 5 stars because it's not the best blade in the world, but for the price you can't beat it. He said that oscillating blades wear out quickly, it's just the nature of the beast. He's tried many different brands. These held up pretty decently. The fact that he got 6 blades for $30 was a good deal.

A great versatile tool

A great versatile tool. I bought the tool to cut in a return air vent grate in my new hard wood flooring. It worked great. It is worth every cent to purchase the higher amp tool. Can't wait to use this tool on upcoming projects.

faster blade changes on Craftsman

Love these. They cut clean, and accurate and straight. I use them with a Craftsman tool, but these are far superior to the Craftsman blades. The slot enables a quicker change without removing the Allen bolt entirely. very nice for long jobs.

Thumbs up

Value is worth five stars. They hold up ok but for the price they can't be beat. Just don't push the tool. Let the blade work its way through and don't let them get hot and they will last.

Rockwell blade set - universal mount

Best buy on Amazon if you're looking for oscillator blades. Comes with 2 each of bi-metal, rough wood, and finish wood cuts. Kit includes two adapters: one for the older Rockwell with the hex mount and one for Bosch and Dremel. I didn't need an adapter for my Porter Cable. The mount holes don't completely bottom out on the bumps due to these being rectangular and the PC being round, but it holds firmly. Better buy this one fast before they figure out how cheap they're selling these blades.

Only OK

I bought these universal blades for my Black and Decker oscillating tool that has the quick change blade option. These are hard to find in my area. The wood blades work quite well. The bi-metal blades did not cut well. I wanted to cut off 2 small toilet bolts, and the blade could not cut one before all of the teeth were ruined. I used the original B&D bi-metal blade to cut both of them, and it is still has lots of life left.

Inexpensive for such quality blades

Love these blades. Through gyproc, metal and wood easely. Longer lasting than my Bosh blades.
