What to check before buying a Bosch angle grinder
Consider the power source first. Corded models like the GWS 13-50 offer unlimited runtime and high torque for heavy jobs. Cordless models like the GWS 18V-50 offer portability but require battery investment. Disc size matters: 4.5-inch discs are common for light work, while 5-inch and larger discs handle thicker materials. Safety features such as a paddle switch, guard, and anti-kickback protection are important for user safety. Finally, check the weight and ergonomics, as a heavy grinder can cause fatigue during extended use.
Mistakes to avoid when choosing a grinder
A common mistake is buying a grinder with too little power for the intended task, leading to slow work and motor strain. Another error is ignoring the battery ecosystem. If you already own Bosch 18V tools, a cordless grinder is a logical addition. Skipping safety features like a lock-off switch or a proper guard is also a risk. Lastly, do not overlook the importance of a good auxiliary handle for control and vibration reduction.
