Random orbital sander

<p>A random orbital sander (also known as a palm sander) is a hand-held <a href="/facts/Power_tool/6sx4n8nr">power tool</a> which <a href="/facts/Sander/qweFHHCV">sands</a> in a random-orbit action. That is, in constant irregular overlapping circles. This technology was first commercially utilized in 1968 by Rupes Tools. Random orbital sanders combine the speed and aggressiveness of a <a href="/facts/Belt_sander/TN5D0d9v">belt sander</a> with the ability to produce a finer finish than that available from a standard, slow speed <a href="/facts/Orbital_finishing_sander/qweFHHCV">orbital finishing sander</a>. Random orbital sanders generally come in three different types: electric powered, air powered, and orbital floor sanders. The electric and air powered orbital sanders are handheld, while the floor orbital sanders are large machines that roll.
</p><p>The random orbit sanding pattern is produced by simultaneously spinning the sanding disk and moving it in small ellipses. This ensures that no single part of the abrasive material travels the same path twice during the same rotation. Because of this random sanding action, the tool does not leave swirl marks, and is not sensitive to the direction of the <a href="/facts/Wood_grain/yyPhv8oP">wood grain</a>. This makes it useful when sanding two pieces of wood that will be fastened at right angles. Random-orbital sanders use <a href="/facts/Sandpaper/tWd80gSw">sandpaper</a> disks, and many include integrated <a href="/facts/Dust_collection_system/mo1jok5Y">dust collectors</a>. Disks are attached using either pressure-sensitive adhesives or a <a href="/facts/Hook_and_loop/1hgh1DvN">hook and loop</a> system. On models equipped with a dust collection feature, a <a href="/facts/Vacuum/BTk3goyV">vacuum</a> sucks discharged dust through holes in the paper and pad, feeding it to a bag, <a href="/facts/Shop_vac/6WNLtcKy">shop vac</a>, or canister.
