Most sander types are powered with electricity, but some of them use compressed air to reach the desired result.
The Types of Sanders Available
Belt sanders are the most common. They use a flat sheet of sandpaper that forms a loop against two rotational wheels, and move at fast speeds. These are quite heavy duty for handheld designs.
Drum sanders are quite large and use a rotational sanding drum to reach the desired result. You send something in to the machine, and it comes out smoothed from the other side. Good for larger projects.
Floor sanders are shaped similarly to a vacuum. It comes with a handle for you to push it against your floors, and it moves along the surface of the floors until the sandpaper cuffs have given it a smooth finish.
Spindle sanders are used for arcs, curves, and other irregular shapes. A sandpaper-wrapped spindle rotates in the center. This type of machine is good for sanding out large projects, like door frames and table edges.
Disc sanders are constructed in a way as to be reminiscent to a cutting saw. It has a dock with a circle-shaped sanding platform that rotates as you move objects into it. It is known for its reliability.
Air sanders, unlike standard sander types, run off of air pressure, which is weighed in PSI, or pounds per square inch. Instead of an electrical supply, these models can be operated with portable compressed air canisters.
Sander Uses and Applications
Portable sanders offer power and maneuverability for small jobs, and if you only have those, then getting one of these is ideal. Possible applications include applying finish to a drawer in a desk. Larger ones exist for larger jobs, such as buffing out a rough surface in thick pieces of wooden paneling for a home.
Pointers for Choosing a Sander
You need to evaluate what kind of work you need from your tool. Then, compare models and prices. As a rule of thumb, larger models will be more expensive than handheld ones. If you have big jobs to do, then you should probably invest in industrial-sized power sanders for those. Simple things around the house are easy to handle.
General Safety Tips for Sanders
• Place the sander over the object before turning it on.
• Never change the sanding disc while the tool is plugged in.
• Never use it unless there is proper ventilation for you.
• Wear protective goggles at all times.
