Bosch Professional GWS 20-230 Angle Grinder

Key specs include a powerful 2000 W motor and a 230 mm grinding disc, dust protection to extend motor life, an ergonomic soft‑grip design for reduced fatigue, anti‑restart protection, a safety switch for controlled operation, and a robust housing that withstands tough job-site conditions.

A 230 mm disc provides greater material removal per pass, deeper cutting capacity, and faster completion of large-area or tough-material jobs compared with smaller 100–125 mm grinders, making it ideal for metal fabrication, masonry work and renovation projects.

It includes anti‑restart protection to prevent unintended startup after power interruption, a safety switch to avoid accidental activation, and a dust protection system to reduce debris ingress. Combined with proper PPE and guarding, these help improve overall on‑site safety.

First unplug the tool, attach the appropriate guard and a compatible 230 mm disc, securely tighten the clamping nut, verify the guard alignment, then plug in and switch on using the safety switch to begin grinding or cutting with a firm two‑hand grip on the soft‑grip handles.

Regularly inspect and clean dust vents, ensure guards and discs are in good condition, replace worn discs, and store the tool in a dry place. Check electrical cord integrity and avoid overloads to minimize wear.

Ideal for metalworking (cutting and grinding metal profiles), masonry cutting and finishing, concrete surface preparation, and renovation tasks where large-area material removal and deep cuts are required.

The GWS 20-230 offers a larger 230 mm disc and higher stock power suitable for heavy‑duty tasks, while the GWS 900-100 is generally lighter and better suited for smaller, more precise jobs.

Both are high‑capacity 230 mm grinders; Makita GA9020 is a strong competitor with its own ergonomic design and build quality. Differences typically lie in weight, balance, and control feel. Compare directly at: https://fepy.com/product/makita-ga9020-9-inch-angle-grinder

Metabo W 650 is another capable 230 mm grinder with its own performance and reliability profile. The intended use and user preference (weight, grip, feel) can influence choice. See Metabo option here: https://fepy.com/product/metabo-w-650-angle-grinder

Consider your job‑site demands: disc size and cutting depth (230 mm), continuous power handling (2000 W), motor protection features like dust protection and anti‑restart, and overall tool weight and ergonomics. Balance these against price and expected usage to determine value.

If the tool won’t start, check the safety switch, anti‑restart function, and power supply. If the disc binds or overheats, stop and inspect the guard alignment and disc condition, allow cooling, and replace worn discs. Regular cleaning of vents helps prevent overheating.
