Makita 9557PB 4-1/2" Angle Grinder
Makita has a huge selection of all sizes of angle grinders. Amongst their small grinders, this model is the best. The 7.5 amp motor operates at 10,000 RPM in an all ball-bearing housing for long life. Like the Bosch, this one will run off of AC or DC current. The vents for the motor use a labyrinth construction, to keep dust and other particles out of the bearings and motor. A nice feature of this grinder is the extra-large, locking paddle switch, for comfortable operation. The gear housing can be rotated every 90 degrees, so you can select the angle which is most comfortable for you.
