There has never been a better time to buy an oscillating multi-tool. Although several multi-platform options were previously available, most oscillating tool users were locked into buying same-brand attachments. With selection, quality and cost varying between brands, this was a less than ideal situation for oscillating tool users.
Things have since changed, and new interface adapters now give oscillating tool users the freedom to select from a wider range of accessories.
Bosch OIS Adapter
Bosch’s OIS adapter fits most modern oscillating tool models and enables the use of Bosch accessories with those tools. Several recent tools, including the Milwaukee M12 cordless multi-tool and Skil Multi-Tasker, are equipped with OIS compatibility straight out of the box.
Right now you can sign up for a free OIS adapter and cutting blade. The offer expires March 31, 2011. Shopping around, it looks like Ohio Power Tool has the greatest selection and best prices on Bosch oscillating tool attachments.
Dremel Universal Adapter
Dremel’s universal adapter is similar in function to Bosch’s, enabling the use of Dremel accessories with other brands’ tools.
Here is a link to a sign-up sheet for a free Dremel Multi-Max accessory adapter. If you’re in a hurry to get the adapter, it can also be purchased for ~$6-7 on Amazon, and works with all Dremel Multi-Max accessories.
Bosch OSCAD1 Adapter Accepts Non-OIS Attachments
Bosch’s OSCAD1 adapter allows Bosch Multi-X oscillating tool users to fit their tools with non-OIS compatible accessories. A similar if not identical adapter is included with the aforementioned Skil and Milwaukee OIS-compatible tool kits. The adapter is currently available on Amazon, but usually sells out quick. You may have better luck finding it locally.
Rockwell Sonicrafter Adapter for Other Brands’ Accessories
Rockwell’s Sonicrafter adapter is used to attach other brands’ accessories to the Sonicrafter’s unique interface. The adapter’s product description specifically mentions compatibility with Bosch and Fein accessories, but it might not be limited to just those two brands.
Although these are the only adapters we’re aware of, there may be others. If you know of any new oscillating tool accessory adapters, please let us know so that we can them to this list. With all of the momentum the multi-tool market has picked up recently, we expect to see even more options in the future.
