Which angle grinder is best for a professional who uses it daily?

For heavy daily use, verified-purchase consensus favors the brushless premium tools: the DeWalt DCG413B and Milwaukee 2880-20 cordless grinders and the corded Makita 9557PBX1 all combine high ratings with large review samples. Brushless motors generally run cooler and last longer than brushed units, which matters most under sustained professional loads.
