10 Best Oscillating Spindle Sanders [2022 Reviews and Guide]

10 best oscillating spindle sanders

Last updated on October 23rd, 2022 at 10:43 pm

There are different types of sanders available for sanding wood, most of which are for sanding flat and even surfaces. However, if you want to sand uneven surfaces, shapes, contours and arcs, what you need is an oscillating spindle sander.

As a woodworker or furniture maker, there’re many applications for it. For instance, after cutting curves on a wood piece with a bandsaw or a scroll saw, there’re bound to be bandsaw marks on the edges.

With the help of the Oscillating spindle sander, you can smoothen up the edges when you pass it through the fast rotating and oscillating spindle.

Apart from sanding curved edges and contours, they’re also great for eliminating defects like bumps and uneven edges even on straight workpieces by simply constructing a straight fence around the spindle as a guide for your workpiece. Ultimately, it’s a tool for refining the edges of your workpieces after they have been sawn.

A typical oscillating spindle sander consists of a rotating circular drum covered with a sleeve of sandpaper which also oscillates or moves up and down simultaneously to prevent the rotating action of the drum from burning the material being sanded.

The up and down motion of the drum also ensures that the wear on the sandpaper is spread evenly, ensuring a longer lifespan for the sandpaper.

Here’s a video on how to use it, demonstrated by Nicholas Kosloski.

What To Consider When Making Your Choice

There’re different types and sizes of oscillating spindle sanders you can choose from. Each produced by different manufacturers with different set of features you can choose from, and each suitable for certain types of projects.

Not everyone will be suitable for you depending on the type of project you want to undertake with it.

Here’s how we chose the 10 listed here on this post, and here’s what you should look for when making your choice.

Size

When it comes to size, oscillating spindle sanders comes in three main sizes or models which include floor models, benchtop models and portable or handheld models.

Floor models

As the name implies, floor model oscillating spindle sanders are heavy duty units that are meant to be positioned on the workshop floor.

They’re floor-standing units that are very heavy with most weighing over 300 pounds, so it even makes no sense to place them on top of anything, except a rolling stand.

As you can tell, they’re also the most expensive. They come equipped with more powerful motors, over 1 HP and a larger table top to accommodate large workpieces.

You should get this if you’re professional woodworker who will be using it daily in the workshop. If you’re just a weekend warrior who just needs it for weekend projects, you should probably get something smaller and less costly.

Benchtop Models

A benchtop oscillating spindle sander is designed to be used on top of a workbench or any flat table top. These are much smaller and lighter than floor standing models and are very useful for both workshop and jobsite projects.

They’re ideal for jobsite projects because you can pick it up by yourself, put it in your truck and take it to the jobsite. Most weigh just over 30 pounds, so carrying it yourself is usually not a big deal.

You can get a benchtop model spindle sander whether you’re a professional woodworker, a simple DIYer or weekend warrior.

They have smaller work tables but are usually large enough for most of the jobs you’ll ever do on a machine like this.

Portable or Handheld Models

A portable oscillating spindle sander is a simple handheld oscillating sanding tool you can use to sand curves on really large work pieces.

These are often ideal when the workpiece is too big to be handled on top of a floor-standing or portable model. For instance, when working on large assembled furniture.

Work Table

The work table is the part of the oscillating spindle sander where you place the work piece for sanding. The spindle protrudes through the middle of the work table, allowing you to sand the material placed on top of the table.

There’re two main types of tables that come with OSS. It can either be a stationary work table or a tilting work table.

With a stationary table, the table does not move or bevel in any direction. With a tilting table on the other hand, you can move or bevel the table if you’re sanding beveled edges.

A tilting table allows you to work on more complex profiles and curves that will not be possible or more difficult on a stationary table.

Oscillating spindle sanders with tilting tables are usually more expensive than ones with a stationary table.

For instance, this JET JBOS-5 with a tilting table is over $500 while this WEN 6510T that has a stationary table is just over $100. You can guess, the tilting table functionality of the JET JBOS-5 has a lot to do with that price difference.

Motor Horsepower and Spindle Speed

When shopping for an oscillating spindle sander, you’ll see that each comes with a different motor specifications, from ¼ Horsepower to 1 Horsepower and above.

The higher the horsepower, the more powerful the sander is, making it much easier to sand harder materials with it.

You’ll find that benchtop models usually come with ¼ horsepower to ½ horsepower motors. Floor-standing models usually come equipped with motors that are 1 HP and above.

If you’re carrying out light-duty projects like simple craftwork, wooden toys and picture frames, then you can choose one with a ¼ HP motor.

For carrying out medium duty projects like sanding hardwoods, you should go with benchtop units that come equipped with ½ horsepower and above motors.

For heavy duty projects, you’ll likely need a floor model OSS with motors that are 1 horsepower and above.

1. WEN AT6535 Oscillating Spindle Sander

WEN AT6535

The WEN AT6535 oscillating spindle sander is a slight upgrade to the time-tested WEN AT6510. It comes with certain features which the AT6510 doesn’t have.

The most notable of these features is the work table which can be beveled up to 45 degrees, allowing it to accommodate angled workpieces without an issue.

Just like the previous model, the WEN AT6535 comes with a powerful 3.5 amps motor which rotates the spindle up to 2000 times per minute, ensuring that it produces the smoothest surface no matter how rough the material is.

When you get this unit, it comes with 5 different sizes of sanding spindles which are ½ inch, ¾ inch, 1 inch, 1-1/2 inch and 2 inches in size, allowing you to tackle variety of projects no matter how complicate the curve is.

This unit features a secure onboard storage which allows you to store each of these sanding spindles in the machine itself, allowing you to organize them efficiently and prevent them from being misplaced.

As with any other sanding machine, dust collection is very important. That’s why the WEN AT6535 oscillating spindle sander features a ½ inch dust port, allowing you to connect a suitable dust collection system or shop vac which collects all the dust produced during use.

Also included for your convenience are five 80 grit sanding sleeves for your first use of the equipment.

All in all, I believe the WEN AT6535 features everything you need to tackle every project that involves sanding of curves in woodworking pieces, and as with all WEN products I’ve tested in the past, it will stand the test of time.
