Disc sanders are a versatile asset to workshops and facilities of all sizes. There are several different types, including stationary disc sanders, portable disc sanders, and combination belt and disc sanders. Choosing the best one for your needs will depend on your required performance speed, the materials you work with, and your budget.
Disc sanders are power tools that use rotating sanding discs to grind and smooth a wide range of surfaces, including wood, metal, plastic, and composites. This detailed machine, which consists of a base and a table in front of the rotating section, is one of the most commonly used power sanders in woodworking.
If you’re new to woodworking or have never operated a disc sander before, you probably have questions. How does it work? What is it used for? In this article, the team at Red Label Abrasives goes over the different types of disc sanders, their components, and how you can use them to increase efficiency and excellence in your projects.
Disc sanders come in different types, each one especially suited for a particular process or project type. To help you determine which one is most suitable for your needs, we’re outlining the most common types below.
Stationary disc sanders are large and powerful machines designed for heavy-duty sanding tasks. They are often mounted on a bench or stand, which provides a stable and secure work surface.
These sanders have a large disc that rotates at a high speed, (some go as high as 12,000 RPM, allowing for quick and efficient sanding. The discs range in size from 5” to 30” in diameter, and are typically made from abrasive materials like aluminum oxide, silicon carbide, zirconia, and ceramic.
One of the benefits of using a stationary disc sander is its ability to handle large workpieces. The larger disc allows for a greater sanding surface area, which can reduce the amount of time needed to complete a job. Stationary disc sanders also typically have more powerful motors than portable disc sanders, which allows them to handle tougher sanding tasks.
Portable disc sanders are handheld sanding machines that are lightweight, compact, and easy to maneuver, making them ideal for DIY projects and home workshops. They typically have a smaller disc size than stationary disc sanders and are powered by electricity, either from a corded power source or a rechargeable battery.
One of the key advantages of portable disc sanders is their versatility. They can be used for a variety of sanding tasks, including:
A portable disc sander is also relatively inexpensive and takes up less space than a stationary disc sander, making it a good choice for DIY enthusiasts. However, they may not be as suitable for industrial-grade applications.
This type of sander combines a disc sander and a belt sander in one unit. They typically consist of a flat worktable with a sanding belt mounted on one side and a sanding disc on the other. The ability to switch between the two also makes it easier to work on different types of surfaces and shapes.
Overall, combination belt and disc sanders are a great option for those who need a versatile and flexible sanding tool that can handle a range of tasks. However, they may not always offer the same level of performance as a dedicated stationary belt sander or disc sander.
Tabletop disc sanders are small, compact machines intended for use on a tabletop or workbench. One of their main advantages is their compact size. They take up less space than larger stationary disc sanders, making them ideal for home workshops or small workspaces. They are also relatively affordable and easy to use, making them a great choice for beginners.
Random orbital disc sanders use a circular sanding disc to remove material. These sanders are designed to rotate the sanding disc in a random, elliptical motion while simultaneously spinning it on its axis. This creates a swirling sanding pattern that reduces the risk of creating visible scratches or marks on the surface being sanded.
Random orbital disc sanders are particularly effective at removing paint, varnish, and other finishes from wood, metal, or plastic surfaces, as well as smoothing and shaping surfaces. Their sanding discs are usually attached using a hook-and-loop system for easy and quick changing during projects.
Disc sanders are used for a variety of sanding tasks. Depending on the abrasive, they can shape, strip, smooth, and polish materials like wood, metal, plastic, fiberglass, and more. You often see them used in the industries below.
Here are some examples of industries where disc sanders are commonly used:
