The Fein AMM 500 Plus Top AS 71293863000 is a powerful 18V cordless oscillating MultiTool designed for fast, precise and versatile work in interior fitting, renovation, repair, installation and dismantling applications. It combines FEIN's proven MultiMaster technology with the AMPShare 18V battery system, allowing compatibility with AMPShare and Bosch Professional 18V batteries.
With a variable oscillation speed of 11,000–18,500 OPM, the MultiMaster provides controlled cutting, sanding, scraping and tile-removal performance across a wide range of materials. The StarlockPlus tool holder transfers power efficiently to the accessory, while the patented QuickIN system allows accessories to be changed without tools in less than 3 seconds.
This Top AS version is supplied with more than 30 accessories, including E-Cut saw blades, carbide blades, an HM rasp, stopper knife, sanding accessories and a dust extraction device. It is supplied in an L-BOXX 136, making it convenient for professional transportation and organised storage. Battery and charger are not included with this variant.
The integrated anti-vibration system improves user comfort during prolonged operation, while the metal gearbox is designed for durability under demanding workloads. The tacho generator maintains a constant speed under load, and electronic speed control allows the user to adapt the tool to different materials and applications.
