Corded Angle Grinder Preference and Battery Life Comparison

What happens here

The presenter then introduces a corded angle grinder and explains why he personally prefers it over the battery-operated version. He states that he doesn't use the battery-operated grinder much because its battery life is insufficient for tasks that require sustained high RPMs, such as prolonged grinding or cutting metal. He notes that even large 8-hour or 12-hour battery packs drain very quickly under such heavy loads, making the corded option more reliable for continuous, demanding work.

Goal: Understand the limitations of cordless angle grinders for heavy, continuous use.
