The Random pneumatic palm sander with a 150 mm pad, RH156A, is what every operator of a random orbital sander needs, an extremely quiet tool that has exceptional power and reduced vibrations. The newly designed pneumatic sander is the quietest random orbital sander in its category. Additionally, it is available in a choice of orbit sizes to suit your particular application. The body is coated with non-slip rubber for better handling, the throttle lever is designed to support the operator's wrist during operation and indeed fits perfectly into the body of the tool to eliminate "pinch points," the internal balancing of the components results in extremely reduced vibrations and the double-row bearings ensure greater durability and smoother operation.
