The Bosch AG50-10 5 In. angle grinder with slide switch, features a new 10 Amp motor design with direct motor cooling and more air vents. This feature reduces hand blockage to extend tool life and provide higher overload capabilities to prevent overheating. Results from independent testing revealed that Bosch grinders outlast the competition to deliver the best tool lifetime in the market- up to 9 times more life than competitors. Improved carbon brushes offer more than double the lifetime of previous brushes, which means less downtime for maintenance. Additional features include textured housing to provide increased grip options for better ergonomics and tool control.
