Whether you're new to home DIY projects or a seasoned contractor, adding a new tool to your arsenal, especially one that can be used for tons of different tasks, is a worthwhile investment. We have plenty of recommendations after testing countless workshop, mechanic, power, and hand tools for the Men's Journal Tool Awards. One of the workshop tools we were most blown away by was the Fein MultiMaster MM 500 Plus Multitool. Here's why you need to add it to your tool kit now.

What Makes the Fein Multimaster MM 500 Plus Multitool the Best Home Workshop Multitool of 2026

This oscillating multitool, which Fein essentially invented, will rarely leave your hand during home demo and reno projects. With a powerful 350-watt motor and StarlockPlus blade system (great for odd angles), the Fein MultiMaster MM 500 Plus Multitool slices, sands, scrapes, and trims with almost no vibration. Though Fein offers a cordless model, we prefer the corded multitool for the lighter, three-pound weight and all-day endurance. There are cheaper options, but by comparison they’re just that: cheap. If you value control and durability, nothing beats the MM 500.
