Take a good look at the image above. That is how you shouldn’t attach a cutting blade to an oscillating multi-tool.
As you probably read, Rockwell is coming out with a new Sonicrafter X2 and a couple of other Hyperlock & Universal-Fit Sonicrafter oscillating tools. The above screenshot is taken from a demo video uploaded by a major tool distributor who got their hands on an early Sonicrafter tool with Hyperlock feature.
That’s not how you attach cutting blades to an oscillating tool. Or maybe it is. The online retailer who uploaded the video describes themselves as “toolexperts,” so maybe they know better.
I haven’t demoed the new Sonicrafters with Hyperlock feature, so maybe they are designed to clamp oscillating tool accessories on only one side. But even if blades technically fit in such a manner, it is unwise as it risks damage to the accessory, tool, or worse – injury to the user.
Don’t half-clamp oscillating tool cutting blades and accessories. For that matter, never half-clamp any cutting tools or accessories. Always attach blades and power tool accessories as indicated in the user manuals that come with your tools.
