What Is a Disc Sander?

A sander is a tool used to smooth surfaces. Sanders can be used on virtually any material. Commercial model disc sanders are typically a minimum of 12 inches in diameter. Sanders have replaceable sanding pads that come in various grits and are made of various materials to achieve the desired result on a particular type of material, such as wood, steel or even plastic. Disc sanders are regularly found in home woodshops. Home versions often have a belt sander, as well.

Function

Sanders are used to smooth surfaces. Typically a series of grits of sandpaper are utilized to achieve the desired result. A disc sander is usually used for edging operations.

Types

There are a variety of sanders. Hand blocks can be used, and often are, for painting projects. Power sanders include belt sanders, orbital sanders, detail sanders and others. All are designed for a specific function.

Types of Disc Sanders

A disc sander is so named because the sanding surface is round and rotates. The sandpaper is typically adhesive backed and sticks to the rotating surface. Some disc sanders are of the pedestal variety, in which the sander is stationary and the workpiece is brought to it on a work ledge or support. Other disc sanders are handheld. Handheld sanders may also be called disc grinders, although there can be a distinction.

Use

The disc sander is a stationary sanding disc with an adjustable worktable attached. The workpiece is sanded by pressing against the rotating sander. The table allows for a resting area for the piece to aid in moving and adjusting the area being sanded. Generally, the disc is only exposed so that the working area is traveling in a downward direction. This avoids the workpiece being caught and lifted off the worktable.

Warning

Disc sanders can be very dangerous. The nature of the tool means that you must put some weight into pushing the workpiece against the sander. Loose clothing can be caught by the rotating wheel and goggles should be worn to avoid any flying particles.
