There’s a clear difference when you pick up a Fein Multimaster FMM 350 QSL or Supercut oscillating tool and compare it to other options on the market. As we rolled through the results of our best oscillating multi-tool review, Fein landed in the top two spots and no one was surprised.
We talked quite a bit about the advantages you can experience, but now I’d like to dig a little deeper into why the Fein Multimaster is so far ahead of the competition.
Fein Multimaster Design
One of the most glaring differences between Fein and everyone else in our shootout is how little vibration Fein oscillating tools have. The boils down to a design that completely decouples the housing and motor. When you anchor the motor directly to the housing, it gives vibration a direct route to your hands. Fein’s design adds a layer of separation to dampen vibration to a ridiculously low level.
The Fein Multimaster uses a high level of copper in its motor windings, making it more suitable for sustained operation without the risk of burning up. Ball bearings on both sides of the motor help smooth out its operation.
On the front end, Fein uses an all-metal gearbox to protect the gearing and extend the overall life.
We catch some flak from time to time about our collective love of the Starlock system. It’s completely hands-free, which is nice when you’re trying to swap out a blade that’s stupid-hot from friction.
It’s more than just the simplicity of the change, though. Starlock has a large physical connection between the tool and the accessory. That leads to better power transfer and faster cutting compared to the same tool with a different connection.
Contrary to popular belief, Starlock is not an exclusive system to Fein. Fein and Bosch partnered on its development and there are three levels to work with.
Starlock is the most universal of the levels, making connections with Fein and Bosch along with Makita, Milwaukee, Ridgid, and other oscillating multitools.
Starlock Plus loses the OIS-type and keeps just the star in the middle. This is where it shifts to a Bosch/Fein exclusive connection. Starlock Plus tools can use Starlock accessories but not Starlock Max.
Starlock Max brings the design in even more and is something you find on some Bosch multi-tools and the Fein Supercut. All Starlock Max tools can use Starlock and Starlock Plus accessories.
Job Site Effect
Fein makes some pretty bold claims about the results of their innovations. They tell us you can expect up to 70% less vibration, 50% less noise, and 35% faster work progress over the competition. When we tested the tools head to head, the performance backs those claims up.
There’s no doubt that Fein makes premium oscillating tools and there’s a premium price to pay along with it. If you turn to your oscillating multi-tool frequently, the difference is worth splurging on.
