Angle grinder Fieldmann FDUB 70605-0 20V cordless — rotary cutting/grinding tool

The Fieldmann FDUB 70605-0 20V cordless angle grinder is a portable rotary cutting and grinding tool designed for cutting, grinding and surface preparation on metal, stone and masonry. Powered by a single 20V Li‑Ion battery from the FAST POWER 20V series (battery and charger not included), the tool delivers up to 7,500 rpm idle speed and accepts 115 mm abrasive wheels with a universal M14 thread. A robust aluminum body, ergonomic main handle and an additional side handle provide stability and access in confined spaces while maintaining a compact footprint for DIY repairs and light construction work.

Advantages

The cordless design removes limitations imposed by power cables and enables work at remote or hard-to-reach locations. Electronic control manages battery output to make efficient use of the available capacity, and compatibility with standard 115 mm discs means broad accessory availability. The aluminum housing increases durability and heat dissipation during continuous use, and the extra side handle improves control and precision on cutting and grinding tasks.

How to use

Fit a compatible 115 mm disc onto the M14 spindle and secure it according to the disc manufacturer's instructions. Insert a charged 20V FAST POWER Li‑Ion battery into the tool and engage the electronic control. Hold the grinder with both the main and auxiliary handles for improved stability. Start the tool and allow it to reach full speed before applying it to the work surface. Use steady, controlled motions appropriate for cutting or grinding; avoid excessive side pressure on the disc. After use, turn off the tool and wait for the disc to stop rotating before setting the tool down. Remove the battery when the tool is stored or during accessory changes.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, gloves, hearing protection and respiratory protection if cutting dusty materials). Match disc type to the task (cutting, grinding, masonry) and follow maximum speed ratings. For extended work, use compatible 2 Ah or 4 Ah batteries to balance runtime and weight. Keep ventilation slots clear and allow the tool to cool during prolonged use.
