The Fein MultiMaster FMM 250Q Top  features a new quick release blade mechanism which does not require the use of allen keys or bolts. The tool mounting is star shaped to prevent the blade from creeping when cutting. The variable speed head oscillates in an arc of 3.2º at a rate of 14000-21000 movements per minute and the speed can be set to suit the task being performed. Benefiting from a larger motor than its predecessor, the new Fein Multimaster has a 250 Watts high torque motor which allows it to cut metals as well as wood.
