What is a Random Orbit Sander?
They have a round sanding pad (115 to 180mm) which is positioned off-centre on the drive shaft and which can rotate freely or with restricted guidance parallel to the surface. This action of orbital together with the random motion makes these sanders highly efficient at rapid material removal right down to delivering a fine finish by simply changing sanding paper grit.
Finishing work on wood carpentry projects has come a long way since the days of hand sanding with sand paper. for larger, flat-surface projects, a belt sander — a powered devices that moves a sandpaper belt at high speed in one direction — works wonders to remove larger amounts of material. However, after using a belt sander, hand sanding becomes necessary to remove scratches from the sandpaper. If you want to remove less material and smooth out flat services without using just your hands and sandpaper, try a random orbit sander. A random orbit sander is a hand-held, powered device — either by battery or by plugging into an AC outlet — that removes less material than a belt sander, thereby allowing a smoother finish. In addition, the unique movement of a random orbit sander prevents scratches: the sanding surface moves in a circle, but it simultaneously moves in an elliptical motion to ensure that the grains of the sandpaper never cross the same section of wood twice. This gives th
