Rockwell RW8942 Sonicrafter Oscillating Multitool Accessory Adaptor to fit other Oscillating Accessories

This Rockwell Sonicrafter Adapter works very well with my original 13 year old Rockwell Sonicrafter Tool (Model#: RK5102K). This adapter is an OEM Rockwell part, and it comes in original Rockwell packaging. My Rockwell Sonicrafter still works and looks like new, and I use it very often. It is a great tool, however, the OEM Rockwell Sonicrafter blades are getting expensive and harder to find. To circumvent these issues, there are many high quality, and less expensive, aftermarket blades out there made for many oscillating tool brands. However, because of the proprietary hexagonal mounting nut on the Rockwell Sonicrafter, most of the "universal" aftermarket blades won't fit the tool. I guess Rockwell realized this and created this handy adapter that works great for the "universal" blades on the market. This Rockwell adapter is made of metal, and it mounts on the hexagonal nut of the Rockwell Sonicrafter Tool. The adapter has two magnets that (sort of) hold blade in place while the retaining bolt and washer are tightened over the blade. The adapter has little "nubs" on it that fit into the grooves of the universal blades to hold them in place, and keep them from slipping during use. This adapter holds the universal blades in place very well, and I have not needed to retighten the blade retaining bolt at all during heavy use. The little nubs on the adapter could be a little longer, in my opinion, but they seem to work well as they are. Part of the reason that the universal blades may work so well with my particular Rockwell Sonicrafter is that I upgraded the retaining bolt years ago to the newer style bolt with the 15/64" Allen head. The original retaining bolt only has a 3/16" Allen head, and it is hard to tighten down snuggly without stripping out the bolt head. It also wears out prematurely from constant use. The retaining bolt upgrade does the trick to hold the blades tighter, and prevent stripping of the Allen head. For those interested, the retaining bolt upgrade kit is Rockwell part#: RW9157. The upgrade kit includes the larger Allen head retaining bolt, a new blade retaining washer, and a larger 15/64" Allen wrench. Trust me, the upgraded retaining bolt makes a huge difference in how securely the Rockwell Sonicrafter holds the blades, and also extends the life of the Allen head in the bolt. I highly recommend this Rockwell universal blade adapter, especially when used in conjunction with the previously mentioned blade retaining bolt upgrade. This adapter works so well, I will be purchasing another one to have as a spare. The Rockwell Sonicrafter is a great tool, and it will last many years if treated with care.

This worked with my Rockwell Soncicsre so I can use with newer blades. The bumps are round domes instead of cylinders. I was skeptical it would hold the blade well, but it worked well with using 5 minutes straight. I did make sure to tighten the bolt well.

This adapter brings my old Sonicrafter up to date, so that I can use attachments which utilize the more common and more widely available style. It fits over the hexagonal nut on my RK5102K, and easily adapts new accessories. The only thing is to make sure that the center screw is tightened down. It should be checked every few minutes of use, to be sure that it remains tight. If not, there's a chance that the little nubs on the adapter can become worn down too quickly.

It worked fine just as advertised

I have an older Rockwell Sonicrafter and this adapter makes it possible to use the newer blades and accessories. Fits perfectly and holds blades securely.

Perfect adapter for my Sonicrafter oscillating tool. I can add other type of blades now from the other brands. A great addition.

I have one of the original SoniCrafter's and have had a horrible time finding blades that fit since they changed the design. So I have just been cranking down on the bolt to hold blades in place. But this adapter with just the tiny nubs to hold the blade has made a big difference. My son just bought an older house and I needed to cut off a cabinet. My blades would not stay tight until I used this. I recommend highly if you have an older SoniCrafter and new blades.

Have purchased several different kinds of adapters for a couple of different oscillators and this is the only one that actually works and fits perfectly to use with universal blades.

So happy that this adapter was available. I have an older Rockwell Sonicrafter and was having a hard time finding blades to fit it. This worked like a charm. I am happy to be able to pretty much buy any brand blades. I used this adapter so I could undercut my doorways when installing a new floor in my bathroom. The adapter fit well and allowed me to use another brands blade saving me money.

Not great, didn’t last long at all
