This guide takes you through the seven best products on the market so that you can decide which machine best suits your needs. There is also a buyers guide, where I’ll run through all the features you need to look for when shopping for a wide belt sander.

Why is it so important that you pick the best sander? Well, these machines are going to cost you some serious money. This isn’t an entry-level tool, as I’m sure you know. A wide belt sander is a professional finishing machine that will give your enterprise an edge over your competition in both the quality of your product and turnaround time.

You need a sanding machine that turns out quality work consistently and reliably, and you need one that will last you for years.

What’s The Difference Between A Wide-Belt Sander And A Drum Sander?

You might already have a drum sander. If so, you will know that they are handy tools and that they are cheaper than wide belt sanders. They turn out decent work pretty quickly. But (and it’s a big but), they sometimes leave ripples in the sanded surface, and you need to revisit these with an orbital sander. This is time-consuming work that detracts from the automation of the process and affects the consistency and quality of your end product.

Also, a drum sander simply can’t turn stock around as quickly as a wide belt sander.

Drum sanders are a reasonable solution up to a certain level, but for quick turnaround and a reliable finish time after time, wide belt sanders are simply a cut above. Put it like this: I don’t know of anyone who has gone from a wide belt sander back to a drum sander.

This Shopfox sander is a powerful industrial-grade wide belt sander with an impressive array of features. It’s a whopping 37 inches wide and can deal with stock up to 36 ½ inches in width. The machine has a powerful 15 hp, three-phase motor housed in a heavy-duty steel cabinet.

This sander has adjustable platen controls that allow for three different types of sanding, platen up, platen even, and platen down. The platen up position allows for aggressive sanding when you need to remove a lot of material. Platen even is a median setting for regular sanding, and platen down is a setting allowing fine control work in detail sanding for the smoothest of finishes.

The machine has a programmable digital control pad that is easy to master. The machine’s accuracy rating is 0.005 inches, making this Shopfox an excellent sander for producing consistently accurate work.

This is an excellent fully featured wide belt sander that is highly adjustable and customizable, so there’s plenty of scope to get it to perform exactly the way you want. While it’s not the quickest machine on the market, this degree of fine control makes it one of the most impressive products out there. There are three 4-inch dust ports and a safety shut-off bar.

The two-year warranty is a bit disappointing, but this is a sturdy tool that you can expect to work for many years.

  • The adjustable platen and oscillation controls offer a high degree of control so that you can tailor the operation of the machine to get top-quality results

The Safety Speed Cut 3760 is one of the most affordable wide belt sanders that can handle stock up to 36 inches in width. It includes impressive features like photoelectric belt tracking and pneumatic belt tensioning to allow high accuracy and fine control.

This is an attractive and sturdily built machine that’s rugged enough to meet your sanding needs for years to come. If you’re on a budget and don’t mind sacrificing some features like an electronic control panel, then you should consider this machine. If you’re experienced with the use of wide belt sanders, then you’ll be comfortable with the control system.

Five emergency stops are a significant plus in my book since safety has to come before everything else. But just one dust port is disappointing.


  • Good value for a 36-inch capable machine
  • Five emergency stops cover all the bases for safety
  • No electronic control panel


  • The conveyor speed of 18 ft/m is slower than most machines

This is a super powerful sander with a maximum cutting width of 25 inches. This puts it in the mid-range size, but if the stock you’re sanding falls within its parameters, then this might be the machine for you.

It offers some excellent features like a digital, programmable control panel and the powerful fifteen HP 3 Phase drive system, featuring three motors that power sanding drums, the feed table, and the feed system separately.

The Powermatic has good provision for emergencies with safety stops and a disc brake that stops the machine but fast.

This sander looks the part too. It’s a sturdy and chunky steel-cased machine in a cheery yellow. I like the fact that it comes with sanding belts in two grades as well as tools and a toolbox.

Control interface: Digital

This 18-inch machine is Grizzly’s entry-level model, and it packs some fantastic features into a compact unit available at a very competitive price.

It’s a sturdy machine with a compact footprint of just 33” x 40”, so you shouldn’t have any trouble finding space for it in your workshop.

The machine includes many of the specifications that come with the more expensive Grizzly machines, including a disc brake for emergency stops, an industrial rubber conveyor belt with four rubber pressure rollers, and twin 4-inch dust ports.

I’m particularly impressed that there is a digital control pad that allows you to program and automate repetitive table adjustments and cutting specs. The machine keeps you honest, too, since there’s an electric limit switch to prevent damage caused by over adjusting the table. It’s great that they help stop you from breaking your new toy.

Sure, you have to make some sacrifices at this price, and the 5 HP motor running on single-phase power isn’t the most powerful, but this sander still has a very respectable top performance speed of 49 ft/m.

This is an all-around quality belt sander that has received excellent customer feedback.

Many of the other machines on this list have more impressive specifications than this Powermatic machine, but they cost around double the price.

If you’re on a budget and want to benefit from the excellent performance of a wide belt sander, then it’s worth looking at this machine. In a way, you shouldn’t be comparing it with other wide belt sanders but instead comparing its performance to drum sanders. And as I mentioned above, even the most humble wide belt sanders offer a better quality of finish than a drum sander.

A Buyer’s Guide To Wide Belt Sanders

Here are the most important features to look for when you’re shopping for a wide belt sander.

Maximum Sanding Width

Maximum sanding width is one of the major limiting factors of a wide belt sander’s performance. For example, if you will be finishing 34-inch wood panels, you’ll need a sander that’s wide enough to cope with this.

Just make sure you’re getting a sander with a maximum sanding width wide enough to deal with all of your anticipated projects.

Minimum And Maximum Sanding Depth

Make sure you buy a belt sander that can deal with the thicknesses you need to process. Most machines are pretty versatile, and since these are precision tools, some can sand down to thicknesses of just ⅛”.

Control Panel & Measurements

A wide belt sander must be easy to use and operate. An intuitive control panel is a real plus.

You also want a sander that gives you precise digital measurements in your chosen unit of measure. A machine that you can control down to increments of a thousandth of an inch will give your finished work incredible quality and precision.

Perhaps the most important control feature of a wide belt sander is the ability to program the same output time after time. You’ll probably be using your machine to do the same job again and again, and a wide belt sander gives you the ability to create unparalleled uniformity of appearance.

Digital control panels that are accurate up to 0.005 inches are the way to go.

Variable Speed

Wide belt sanders get through stock at an impressive pace. Performance speed is measured in feet per minute. Typically, more expensive machines process stock faster than cheaper units. It’s a good idea to set a target speed that meets the needs of your business.

Make a spreadsheet and work out how many units of whatever product you work with you want to finish per day. You will be able to figure out the total length of stock you need to sand per day and then divide this by the number of minutes in your working day.

Voila! Now you know how many feet per minute you need from your sander. This will help you buy a machine that meets your requirements.

Dust Collection

Wide belt sanders kick out a lot of dust. Remember that these are high-performance quick turnaround tools that sand a lot of stock very quickly. Lots of dust in the workplace doesn’t simply create a cleaning overhead. It’s also a health risk.

All the machines reviewed here feature some form of dust collection. Most machines have several dust collection ports.

You should think about where you plan to install the device. If you’re working in an enclosed space, then dust collection is a big issue, and it’s vital you buy a product with good dust collection ports.

Power Supply

What kind of power supply do you have? Wide belt sanders have different power specifications. Some units can run on single-phase power, but larger machines use three-phase power.

What’s the difference? Well, a three-phase power connection gives you more stability of output than one phase.

Single-phase power supply is vulnerable to fluctuations in voltage that reduce the consistency of power delivery to the machine. Three-phase power provides a stable voltage that allows machinery to work more efficiently.

And three-phase power the advantage of carrying three times as much energy as one phase.

You need to be aware of the power requirements of different machines so that you can either buy one that fits the power specifications of your place of work or upgrade your power supply.

Belt Changing Speed And Difficulty

Sometimes, you’ll need to change an old belt. More often, you’ll need to change belts of different grades of abrasion.

When choosing a wide belt sander, you should check the speed, convenience, and efficiency of belt-changing. A user-friendly construction that allows for the rapid switching of belts will save you time and money.


Wide belt sander mobility might not be an issue for you. After all, these are big pieces of equipment that you won’t often move from place to place.

However, you might need to use your belt sander in several locations. If so, you should look for a lighter model with a rugged design and good casters that make it (relatively) easy to move around.


Safety features are of paramount importance when using a wide belt sander. These include features like multiple safety stops located within easy reach of the machine operator and disc brakes to stop operation quickly. Make sure that you check the machine for safety features like automatic cutouts and protective brakes.
