There is a range of different sanders out there and each one is appropriate for a different type of task.
Tip: No matter which type of sander you decide on, always wear safety glasses to protect eyes from flying debris.
Types of Sanders
Random-Orbit Sanders. Features a round pad that moves in a random pattern to prevent gouging and can handle everything from rough to finish sanding. There are four different types including:
Palm grip sanders are small and easy to use. They are ideal for smaller projects like sanding drywall or stripping furniture.
Pistol grip sanders are larger and usually more powerful. They are perfect for working on tabletops and casework.
Right angle sanders are for heavy-duty use and are better for rough sanding.
Pneumatic palm grip sanders are powered by air compressors.

Safety and Use
When operating any unit keep your hands away from the sander while it’s running. Don’t apply pressure when sanding as it may result n the machine kicking back at you. Orbital sanders with higher orbit-per-minute (opm) rates tend to sand more quickly. Sanders with variable speed provide extra control for working in close quarters or more delicate tasks.
Other safety precautions for operating sanders:
Always follow manufacturer’s safety guidelines
Use respiratory protection for materials that create a lot of sawdust
Wear ear plugs when using noisy sanders to prevent hearing loss
Avoid sanding near sparks and flames to prevent fire hazards
Sanders may be powered with electricity, batteries or air compressors.
Electric sanders are usually more economical and portable.
Pneumatic sanders require the purchase of an air compressor and are often more powerful and work faster.
Sawdust Collection. Bags used to collect dust or ports that give you the ability to hook the sander up to a dust collection system or wet/dry vac to whisk away debris.
Trigger Lock. Allows you to keep the unit locked in the on position without having to manually depress the trigger.
Clamps. Usually used with more portable sanders for delicate jobs, they allow you to lock sanders in an upside-down position to create a sanding stand.
Grips. Two-handed or large front grips make it easier to guide the sander accurately.
Portability. Easier to move sanders to and from different areas when using a carrying case and a long cord.
Pad Brakes. Allows you to lift the sander from the work surface and put it back down without gouging the material.
Tracking Adjustment. Knobs or thumbscrews that make adjusting the tracking quick and easy.
