Portable circular saw Fieldmann FDUK 70305-0 is a cordless 20 V Li‑Ion powered saw with a 165 mm (16.5 cm) blade designed for cutting wood and similar materials. The saw reaches up to 4300 RPM idle speed and is part of the FAST POWER 20V battery program, accepting 1 × 20 V batteries with 2 Ah or 4 Ah capacity (battery and charger sold separately). The tool combines a compact, cable-free design with an aluminium base and an integrated laser guide for straight cuts, making it suitable for on-site carpentry, renovations and DIY tasks where mobility and ease of handling are important.

Advantages

The cordless design eliminates the need for mains access and increases portability for outdoor or site work. Built-in electronic control optimises use of the Li‑Ion battery capacity to maintain consistent cutting performance. The aluminium base provides a stable, wear-resistant support while the integrated laser helps to align cuts precisely. Compatibility with the FAST POWER 20V battery range allows sharing batteries across other Fieldmann tools.

How to use

Fit a charged compatible 20 V battery into the saw according to the manufacturer’s instructions, ensure the blade is correctly installed and secured, and confirm the aluminium base plate is clean and positioned on the workpiece. Mark the cutting line and switch on the laser to align the guide with the intended cut. Start the saw and allow it to reach operating speed before advancing steadily through the material. After cutting, release the trigger and wait for the blade to stop before setting the tool down or removing the battery.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, hearing protection and dust mask) and secure the workpiece before cutting. For longer cuts or thicker material, use a fully charged 4 Ah battery to maintain performance. Keep the aluminium base and laser lens clean for accurate guidance and check blade condition regularly; replace the blade if it shows wear or damage.
