Angle Grinder Metabo WB 18 LT BL

The Metabo WB 18 LT BL angle grinder is a cordless tool designed for grinding and light cutting tasks. It is powered by an 18 V LiHD battery system and features a brushless motor for improved efficiency and longer service life. The grinder accepts a 125 mm (12.5 cm) grinding disc, reaches a maximum no-load speed of 10,000 RPM and provides a maximum cutting depth of approximately 27 mm. With a net weight of around 1.8 kg and a compact, ergonomic housing, the tool is intended for applications where mobility, low weight and steady performance are required.

Advantages

The brushless motor reduces maintenance and increases runtime under load compared with brushed alternatives. Battery-powered operation removes the need for a power cord, enabling use in locations without mains supply and improving maneuverability. A small, lightweight form factor (about 1.8 kg) helps reduce user fatigue during extended tasks. The 125 mm disc size provides a balance between compactness and cutting or grinding capacity, while the 10,000 RPM top speed allows efficient material removal for common grinding applications.

Suitable for

• Grinding and surface preparation on metal and weld seams
• Light cutting of metal profiles and rebar
• Removing rust, paint or scale with appropriate abrasive discs
• Portable jobsites and maintenance tasks where mains power is unavailable

How to use

Fit a suitable 125 mm grinding or cutting disc that matches the intended material and observe the disc manufacturer’s instructions. Ensure the battery is charged and correctly inserted before switching the tool on. Hold the grinder with a firm two-handed grip, position the disc at the required angle to the work surface, and apply steady, controlled pressure—avoid forcing the tool. After finishing the cut or grinding pass, release the switch and allow the disc to stop completely before setting the tool down. Follow safety precautions such as wearing eye and hearing protection and using appropriate gloves and respiratory protection when working with metal dust or coatings.

Usage recommendations

Use abrasive discs rated for 125 mm and suitable for the material; select cut-off wheels for cutting and flap or fiber discs for grinding and surface finishing. Replace batteries with charged units to maintain consistent performance on jobsite tasks, and inspect discs and guard components regularly for wear or damage. Observe manufacturer guidance for safe operation and battery care to prolong tool life.
