The 5" 12 Amp Paddle Switch Disc Grinder w/ Brake G13BYEQ2 offers exceptional performance for the operator with five safety features that reduce user fatigue and injury risk. The robust 12 Amp brushless AC motor delivers a no-load speed of 8,500 RPM which allows you to take on a wide variety of grinding tasks. The brushless motor is ultra efficient and permits the use of extra long extensions cords without reducing power loss, extends product life and eliminates maintenance of armatures or carbon brushes. 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 removeable dust filter offers additional protection for the motor against dust and debris, ensuring the tool is operating effectively as desired. Superior performance is achieved when using a generator via an internal inverter circuit that regulates uneven power supply.
