FAQ Common Questions
What is the average runtime of a cordless angle grinder
Runtime varies based on battery capacity and application. A 4.0Ah battery typically offers 30-45 minutes of continuous use under moderate load. Using higher capacity batteries, like a 6.0Ah or 8.0Ah, significantly extends operation time for longer projects.
Can a cordless model match the power of a corded angle grinder
Yes, for the vast majority of applications. Top-tier cordless models now generate sufficient power and RPM for cutting rebar, grinding welds, and slicing stone. The key is using a high-voltage battery system (18V/20V MIN or higher) designed for professional tools.
What should I look for in a professional cordless angle grinder
Prioritize a brushless motor for efficiency and durability, a robust battery ecosystem you may already use, and safety features like an electric brake. Consider the tool's ergonomics and weight, as it impacts control and fatigue during all-day use.
