First Look: New Rockwell Sonicrafter X2 OMT

September 20, 2012 | by Ethan (email) |

You’ve probably seen the press releases and stock photos of the new Sonicrafter X2 making the rounds. I’ve found it’s tough to get a real sense of a tool and how well it performs before it’s in your hands. That’s why I’m excited that we have the new X2 in our shop, and so far I’m really impressed.

The Sonicrafter X2 (model #RK5139) is one of four new offerings from Rockwell that will be available in October 2012, and the X2 has several key features that I really like.

Tool-Free Accessory Changes

I hate keeping track of those Allen keys to swap out accessories so I’m a big fan that more and more OMT’s are offering tool-free accessory changes. To change blades on the X2 you flip the top lever and rotate it in the unlock direction, insert the new accessory and lock it in place.

Rockwell takes it one step further with their Hyperlock design delivering “one ton of clamping force”. I’ve found that some OMT’s (like my Dremel) have a hard time holding onto the blade especially when I’m cutting through dense material. The Hyperlock clamp seems very secure so I’m hopeful that won’t be a problem.

3.0 Amp Motor

Previously only Bosch and Ridgid offer a 3.0 amp OMT (unless I missed one?). I was glad to see Rockwell upgrade the motor to 3.0 amps compared to the prior generation’s 2.3 amp motor.

Universal Fit Accessories

I’ve gathered quite a collection of OMT accessories from Bosch, SKIL, Ridgid, Rockwell, Dremel and Imperial Blades to name a few. Rockwell’s new X2 is compatible with just about all competitors’ accessories. However, depending on the tool interface they may not be as easy to use.

Plus, Rockwell Universal Fit accessories are designed to fit on any multi-tool you already own.

The X2 comes with 8 typical accessories for cutting, sanding, scraping and grinding. Rockwell also includes another accessory called the Sonishear Scissor attachment which handles materials up to 5/16″ thick.


Rockwell has a new case for the X2 for storing the tool and accessories. It’s compact, waterproof and features two storage areas on top for easy access.

    I have an inexpensive model I got on sale at Menards for $20. Since I don’t use it that often, it works just fine for me. I would have a hard time justifying $149 for a more high end set. But then again, it’s not something I use that often.

  2. poiboybf says:

    Looks nice! I like that it is compatible with most of the other models on the market. Mine is DeWalt… I like it a lot but I don’t think it’s a 3.0. Thanks!

    I like tool free accessory changing. My Nextus Mutli-tool requires a custom allen wrench.

  4. Chris says:

    I really want to get one of these OMT’s. I just never have a big enough need to justify the price. They do look really cool though. Thanks for the review

    • Ethan says:

      This is a really great option, especially because the Fein is so pricey. Also, so many people I’ve talked to say “I don’t know what I’d do with an OMT”. Then after getting one, they use it all the time.

  5. MissFixIt says:

    Seems like a amazing tool. With the interchangeability makes it even better. We were looking into getting one here because the stupid builder put the baseboards on THEN tiled. So we need to cut out the baseboard when we go to replace them. They look awfully short and nothing like a baseboard should look like.

  6. trebor says:

    It took me quite a few Google searches to find out that OMT standard for oscillating multi-tool :S

    Looks handy though. I could how once you have one, there’d be a lot of opportunities to find ways to put it to use

  7. Brady says:

    Does anyone have experience with owning an OMT for a while (and getting fairly use out of it)? I’d like to know how long the blades and accessories last. Also, does anyone have a list of the tasks that can be accomplished with one? I truly believe that one of these could replace a multitude of other tools.

    • PhotoEthan says:

      I’ve had one for about a year and a half and I find that it is indispensable for certain tasks. The plunge and flush cutting ability is something that is hard to duplicate with any other saw besides maybe the Bosch Finecut, but the Finecut is really limited to flush cutting and can’t get into the tight spaces that an OMT can. As for the tasks, I’d take a look at a few manufactuerer’s websites and they’ll tell you but I’ve used mine for cutting back framing, drywall, nails (won’t work on screws they’re hardened), undercutting doorjambs and casing for flooring jobs, sanding, stripping paint, adhesive and caulk, removing grout, etc… etc… etc… I wouldn’t say they are a replacement for a lot of tools but they can do a lot of things that used to be strictly the domain of hand tools.

  8. Reuben says:

    I definitely need to get on the oscillating tool bandwagon. Everybody’s getting them these days and they look really useful. It’s so hard for me to tell all the brands apart, though.

  9. Joe says:

    How do those crazy looking scissor things work? Did you at least mutilate some paper to try them out?

  10. Reuben says:

    I recently bought the Bosch MX30. I’ve only used it once, but I’ve been pretty impressed. It also has the tool-free blade change feature, which is really nice. Any idea if the SoniShear scissors will work on a Bosch? It doesn’t sound like the Bosch is quite as advanced at accepting blades from other manufacturers?

    • Ethan says:

      Not sure about using the SoniShear on the Bosch, and I don’t actually have a Bosch unit to try out. Rockwell did a good job making their OMT and accessories compatible with competitors. I bet they integrated better than Bosch.

  11. HANDYMAN51 says:

    Anyone out there use the SoniShear for haircuts? Do they slice through ears very often? ( DON’T try this at home!)

  12. Christie says:

    I have used this tool to completely redo a trailer from inside and out. This is truly one of the most amazing tools. I used it for Cutting 2 x 4s out off walls to cutting trim on baseboard. I’ve used it forgetting sheetrock for light switch covers. This is Saved me an enormous amount of time and energy. This is truly the best tool I’ve ever had in my possession.
