A sander is a standard tool used during carpentry, two of the most common sanders are the belt sander and disc sander. These power tools are often used to soften wood by abrasion using sandpaper. There are several types of sanders, and you need to know the differences and uses of each.
Disc Sander & Polisher
A disc sander smoothens and polishes the wood and is commonly referred to as a stationary machine sander. It’s called this because a disc sander is often held on a table. Circular sandpaper is attached to the disc sander. With the disc sander, you’ll need to bring the piece of wood you need to sand the machine. You can adjust the disc sander to various angles, depending on your needs.
When using the disc sander, always place the protector in place. This is so you can avoid using the wrong part of the rotary disc. This type of sander is also equipped with a dust extraction unit that extracts dust particles produced during sanding. Apart from wood, you can also use the disc sander for other materials, including plastic, aluminium and other softer materials.
A belt sander is a sander that can be both handheld or stationary. The belt sander has of an electric motor that rotates a pair of drums while joining a seamless, or belt-like loop of sandpaper.
The belt sander can be used as a portable sander. A belt sander comes in various sizes. You can find a small hand machine or a unit large enough to accommodate a large sheet of plywood. Similar to a disc sander, a belt sander also comes with a dust extraction system that captures or extracts dust particles during sanding. For a belt sander, a bag or bag attached to the machine is often used to capture the extracted dust.
Choosing the Right Sander
Choosing the right type of sander will largely depend on the type of sanding you need. Both the disc sander and the belt sander are power tools that can significantly assist your sanding tasks, but you need to know which one to use for a specific sanding job.
A belt sander is ideal for any sanding job that requires a large amount of material to be removed quickly, such as disassembling paint or finishing on flat surfaces, smoothing wood filter patches, sanding hardwood floors, or remove hardened glue. Before using the belt sander, it is necessary to turn on the sander before applying the sanding pad to the surface of the wooden part.
On the other hand, if you need to finish wooden surfaces or prepare surfaces, a disc sander & polisher should be used. You should use a disc sander when you are ready to prepare, varnish or paint a piece of wood, as it provides a smoother finish.
