Best Disc Sander

To determine the best disc sander we looked at a range of criteria such as disc/belt size, speed, sander type, weight, materials, and size. You’ll note in our guide that we’ve featured a range of electric sanders that include handheld belt and disc models plus combination belt disc sanders. But regardless of the type of sander you choose, you want a powerful sander with a sufficient RPM/FPM/OPM rating to support your tasks. Likewise, you’ll want a power tool made of sturdy materials that minimize vibration and is heavy enough to stay put when in use. And finally, you’ll want to match the disc size to the project.

Because of the above factors, we selected the WEN 6502T4.3 Amp 4 x 36 in. Belt and 6 in. Disc Sander as our Top Pick. This combination model is designed from cast iron for a strong base that resists vibration and features a disc sander that can reach up to 3,600 RPMs while the belt can reach up to 2,100 FPMs. This combination belt disc sander also comes with multiple belts and disc grit replacement pieces to keep you moving through your project, and also features standard options like an adjustable vertical and horizontal tilt on the belt and disc respectively.

How We Decided

Anyone who works with wood or finds themselves constantly sanding knows that a powered sander can streamline the process and cut down on project timelines. But powered sanders come in a range of models, so we focused solely on handheld belt and disc sanders as well as combination belt disc sanders. To narrow down the field, we considered the following criteria — disc/belt size, speed, sander type, weight, materials, and size.

Within our buying guide, you’ll find that there’s an even representation across the various sander types (handheld belt and discs, plus combination belt disc sanders). While we only offer one handheld belt sander (our Honorable Mention/Best Budget), we also have two handheld disc sanders (#3/Best Quality and #5), and the rest of the options (our Top Pick, #4, #6, and #7) are combination belt disc sanders.

Speed can be broken down into amperage as well as the RPM/FPM/OPM rating for the machines. The higher the RPM/FPM/OPM, the faster you can power through a project. Except for our #6 pick, we’ve included the RPM/FPM/OPM ratings to help you narrow your search. Note that these speeds can vary between models. And depending on your needs, you may be more focused on RPMs or OPMs which refer to disc speed as opposed to FPM which refers to belt speeds.

Next, we considered the disc and belt size. Without exception, any of the belt sanders (including combination models) feature belts that measure four inches wide by 36 inches long. However, with the disc sanders, we have a range of models between five and six-inch diameters. But we also considered weight and size. By default, all of the handheld sanders (Honorable Mention/Best Budget, #3/Best Quality and #5) will offer the smallest size and lightest operation experience. But we did select the #7 as the best small combination belt disc sander for smaller shops whether you’re a DIY enthusiast or outfitting your professional shop.

Finally, we considered the materials. For combination belt disc sanders, cast iron material is preferred over other materials such as cast aluminum. You’ll note that of our combination models, our Top Pick and #6 options are made from cast iron whereas #4 and #7 are designed from cast aluminum. With handheld models, the emphasis is on comfort dual grips that provide added stability — which is available on all of the models on our list.

Disc Sander Buying Guide

The Most Important Features to Consider

  1. Disc/Belt Size
    When you’re buying a disc sander, one of the most important features you need to consider is the disc size. This refers to the diameter of the actual sanding disc and can range between five to 12 inches with most models between five to eight inches. Smaller discs are ideal for working on projects where you’re focused on less surface area. In contrast, a larger disc sander can help to cut down your sanding time. For belt sanders, the most common size you’ll find is four inches wide by 36 inches long.
  2. Materials
    No one wants to find themselves constantly replacing power tools with every project. To prevent this, look for disc sanders that feature more durable metal material versus models made of alternative materials. Specifically for belt disc sanders, look for models made from cast iron to add to their durability and weight to prevent movement during operation.
  3. Weight
    Power sanders can be powerful tools but you can find them in a variety of weights to fit your needs. While heavier isn’t always a guarantee of better quality, it’s usually a good bet to focus on heavier weight disc sander models as these also tend to last longer than lightweight models.
  4. Speed
    In addition to the disc size, you should also consider the speed. For belt sanders, this is referenced in feet per minute (FPM) whereas disc sanders will cite rotations per minute (RPM). Lower speeds are better for hardwoods whereas high-speed discs are perfect for use with softwoods. But as opposed to buying multiple disc sanders, consider purchasing an adjustable speed disc sander so you can work with a variety of materials.
  5. Handheld vs. Stationary
    Disc sanders come in a range of styles, specifically handheld versus stationary models designed for table mounting. The version you select is going to depend on your project. Stationary models are typically combination belt disc sanders, making them ideal for use with smaller items. Handheld models are great for use with larger projects where it wouldn’t be logistically possible to sand an item with a table-mounted disc sander.
  6. Angles
    Angling is an important feature specifically for combination belt disc sanders. Typically, you’ll find that the disc attachment features a miter gauge that usually allows you to angle your project typically between zero to 45-degree angles for enhanced precision. Likewise, the belt sander can be titled between zero to 90 degrees.

Disc Sander FAQs

What’s the difference between a disc sander and a belt disc sander?

A disc sander is typically a handheld, portable sander that only features a sanding disc. These can be battery powered for true portable freedom or corded — which frees you from needing to recharge the batteries constantly. In contrast, a belt disc sander (also known as a combination belt disc sander) is a stationary tool that’s designed to be mounted to a tabletop. These models feature two sanding options — a narrow belt sander and a sanding disc pad. Whether corded or battery-powered, handheld disc sanders are ideal for use on larger projects or when you need to be mobile to reach corners and areas that wouldn’t be practical with a belt disc sander. Belt disc sanders are perfect for working on smaller items like blocks of wood where you have total control over the item being sanded.

Should I get a belt disc sander or a handheld disc sander?

This is going to depend on the types of projects you find yourself completing. If you primarily work with small items, a combination belt disc sander might be ideal for you. But if you find yourself working on very large projects where it would be unrealistic to safely use them with a belt disc sander, then a handheld disc sander is a better option.

How do I determine the right grit to use with my sander?

This is going to depend on the work you do. Lower grits such as 60 are ideal for heavy sanding whereas higher grits between 100 and 200 are better for precision shaping and finishing projects.
