Anyone who has tried to refinish a piece of furniture by hand knows that sanding even a small area takes a great deal of energy. This job can be transformed from an overwhelming chore into a manageable task by relying on the right power sander. There are many types of sanders, and the right one depends upon the job.

Detail Sander - is a light hand-held sander with a small pad for sanding where other power sanders can't, such as the inside corners of a box or uneven surfaces. Usually used for finishing sanding.
Orbital Sander - is a small sander, they come in 2 sizes either palm size to fit Â¼ sheet of sandpaper or large to fit Â½ of a sheet of sandpaper. Orbital sanders rotate the paper quickly around one center point. Orbital sanders don't remove a lot of material and may leave a circular pattern on the material.
Random Orbit Sanders - is a small sander that orbits and spins the sandpaper. This motion is more aggressive in removing material than an orbital sander and is less likely to leave circular marks.
Belt Sanders - are large sanders that rotate a sanding belt that is stretched between two rollers. Belt sanders are ideal for removing large amounts of materials (e.g. paint, varnish, wood) over large areas. Belt sanders will leave a large scratch pattern in line with the direction of the rotating belt.
Dust Collection - for sanders that remove a large amount of material (random-orbit and belt) a dust collection bag or vacuum hose attachment is ideal.
Size - All sanders come in many different size ranges. Choose the size that is appropriate for your average job. A sander that is too large will be harder to maneuver.
Variable Speed - Belt sanders may have switches to adjust the belt speeds. This is feature can make the sander more versatile and lower the likelihood of damaging the material.
Overall Design - Look at the location of the power cord, will it get in the way? How does the handle feel, it is comfortable? Pick up the sander. Is it well balanced?
