The Fein Cordless Multi Master AMM 500 Plus AS N00 71293862000 is a professional 18V cordless oscillating MultiTool designed for fast, precise and versatile work in interior construction, renovation, installation, repair and maintenance applications. It combines efficient cutting performance with a highly versatile StarlockPlus tool mounting system, making it suitable for a wide range of professional jobs.

The AMM 500 Plus AS features a powerful DC motor that delivers performance comparable to the mains-powered version while providing the mobility and convenience of cordless operation. Its variable oscillation rate of 11,000–18,500 oscillations per minute allows users to adapt the tool speed to different materials and applications.

The StarlockPlus tool holder provides efficient power transmission with minimal loss, helping deliver improved cutting performance and precision. The patented QuickIN rapid-clamping system enables accessories to be changed in less than 3 seconds, reducing downtime when switching between cutting, sanding, scraping and other operations.

An integrated anti-vibration system helps minimise vibration and provides comfortable operation during prolonged use. The tool also features excellent noise insulation for improved operator comfort in demanding workshop and construction environments.

The Tacho generator maintains a constant speed even under load, while the infinitely variable electronic speed control allows the operator to select the appropriate operating speed for the material and application. The robust all-metal gearbox is designed to withstand high loading and provide excellent durability and service life.

The AMM 500 Plus AS is part of the 18V AMPShare battery platform and is compatible with AMPShare / Bosch Professional 18V batteries. Electronic Cell Protection (ECP) helps protect compatible batteries against overload, overheating and total discharge, while COOLPACK technology supports longer battery service life and extended operating periods.

The exact 71293862000 variant is supplied in an L-BOXX 136 with a Universal E-Cut saw blade 44 mm. Importantly, this particular variant is supplied without battery or charger, allowing users who already own compatible AMPShare batteries to purchase the tool without duplicating their battery system.
