The 4-1/2" 12 Amp AC Brushless Variable Speed Angle Grinder G12VE2 offers exceptional performance and flexibility with six speed settings for more control. This is the tool you need whether you are polishing/finishing, removing paint, rust, burrs, grinding or rough grinding. The robust 12 Amp brushless AC motor delivers a no-load speed of 2,500 to 8,500 RPM, which allows you to take on a wide variety of tasks. The brushless motor is ultra efficient and permits the use of extra long extension cords with reduced power loss, extends product life and eliminates maintenance of armatures or carbon brushes. Provided safety features are kickback protection, zero voltage restart and soft start. A tool-less wheel guard and 3 position side handle provide the user increased operational efficiency. An anti-vibration side handle is included for user comfort. A removable dust filter offers additional protection for the motor against dust and debris and ensuring the tool is operating effectively as desired. Superior performance is when using a generator via an internal inverter circuit that regulates uneven power supply.
