Random Orbit Sanders are handheld electric devices for sanding where the sanding blade provides a random orbital action. That is, the angle of rotation of head and disk varies. Perhaps it was first introduced in 1976 by Festool but in 1982, a random orbital orbit incorporating speed and aggressiveness (again by Festool, Festo in 1982) from a sander belt with the ability to produce a finer solution than was available from a standard, slow speed of orbital sand sanding. Random orbital sand generally comes in three types: electric-powered, air-powered, and orbital floor sander. Electric orbital stirrer and hand-held air, while the floor orbital sander is a large rolling machine.
The sanding pattern of random orbits is produced simultaneously by rotating the sanding disc and moving it in the form of a small ellipse. This ensures that no single part of the abrasive material travels the same path twice during the same rotation. Due to this random sanding action, it does not leave spinning marks, and is not sensitive to the direction of the wood grain. This makes it useful when sanded two pieces of wood to be tightened at right angles. Sanding a random orbital using a disk sanding, and many including integrated dust collectors. The disk is attached using pressure-sensitive adhesive or hook and loop system. In models equipped with dust-gathering features, the vacuum sucks dust thrown through holes in paper and pad, inserting it into a bag, store, or canister.
