A multi-tool is one of those things you can’t understand just by looking at it. You have to try it once to understand why it’s so valuable. And once you use one, you’ll wonder how you ever managed home improvement and repair work without one. I use one constantly—to start cutting, trimming, sanding, scraping, and making cuts in hard-to-reach places where a handsaw or even a power saw can’t fit. When I was renovating my bathroom, a multi-tool for cleaning grout was a real lifesaver.

I’ve been thinking about upgrading to a cordless model lately, because it’s 2025 and I’m sick of the constant tangle of cords. So I was drawn to this Prime Day deal: the Flex 24V Brushless Cordless Oscillating Multi-Tool is 45% off until the end of Prime Day (saving over $75).

Reviewers praised this multi-tool, noting its smooth operation without the irritating vibration and shaking common to some models. With an oscillation rate of up to 20,000 vibrations per minute (OPM), it’s powerful enough to cut almost anything, including metal pipes, 2x4s, and drywall. The high oscillation rate means the tool cuts quickly, saving you time and protecting your hands from fatigue. The battery lasts a long time (although the discount only applies to the tool; if you don’t have the Flex battery and charger, you’ll need to buy them separately or as a kit ).
