The Bosch AG40-11P 4-1/2-Inch 11-Amp High-Performance Paddle Switch Angle Grinder, features a new motor design with direct motor cooling and more air vents to reduce 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 60 percent more life than competitors. A new motor design featuring direct motor cooling and more air vents to reduce hand blockage help extend the tool life and provide higher overload capabilities to prevent overheating. Additionally, improved carbon brushes offer more than double the lifetime of predecessor brushes, which means less downtime for maintenance. The new grinder offers up to 2 amps more power than previous generation models to deliver the robust performance demanded by professionals in industries such as metal fabrication, energy, masonry and restoration. The AG40-11P features a new patented multi-grip paddle switch and textured housing to provide increased grip options for better ergonomics and tool control. The first-to-the-market multi-grip paddle switch can now be operated in the front, middle and rear – as opposed to only in the rear on old models – to allow users to hold the grinder in any position. More air inlets also ensure hands are not blocking air flow. Kit Includes: AG40-11P Tool, Grinding Guard, Vibration Control Side Handle, Lock Nut, Backing Flange and Spanner Wrench.
