What makes a great cordless oscillating multi-tool and what makes FEIN Power Tools the best?

FEIN’s design uses four flexible damping elements to completely isolate the housing from the motor to reduce vibrations by up to 70 percent and noise up to 50 percent when compared to the previous model.

Quick-Change Blade Mounting System

Key to ease of use it the blade changing system on any power tool and the same is true of a multi-tool.  FEIN Tools has invented the StarLock Mounting System that eliminates pins and requires no tools to operate.  Using StarLock, blade accessories can be changed out in three seconds or less.



Don’t let the quick-change system on a FEIN multi-tool fool you.  The unique geometry of the FEIN multi-tool tool head in combination with StarLock accessories guarantees a solid connection and the transfer of power to the workpiece. The accessories simply snap into the tool head for a secure and accurately seated connection and they are also easily released by lifting the lever on the tool head.


We searched tool forums, social media, manufacturer sites, consumer sites, customer review sites, and retail sites to find the most popular and highly rated multi-tool.
