Where you’re a pro or a hobbyist, taking a woodworking project from good to great requires a bit of an edge—quite literally. Use one of the best spindle sanders to achieve smooth, even edges on woodworking projects.
Unlike bench sanders, these handy tools use spinning cylindrical sanding drums (called spindles) and flat work surfaces to sand curved boards and joints to a consistent finish. Not only do they spin the drum to sand quickly and efficiently, but the best spindle sanders also oscillate up and down to alternate the sanding direction, removing the chances for grooves or scratches in the workpiece.

What to Consider When Choosing the Best Spindle Sander
Consider a few points when shopping for a spindle sander. From the type of spindle sander to its size and speed, learning how these tools work and what they can do helps shoppers find the best spindle sander for their needs and workshop setup.
Type
The three main styles of spindle sanders are benchtop, floor standing, and portable. All three types work similarly, but differ in size and setup.
- Floor-standing spindle sanders are taller units that stand on their own base or legs. The work tops are usually at a relatively comfortable height, making them easy to use. But they’re heavy, sometimes weighing as much as a few hundred pounds, and they take up quite a bit of floor space.
- Benchtop spindle sanders are designed to sit on top of a workbench or table, allowing the user to set them up anywhere with a flat surface. These models are much lighter than floor-standing models, often weighing just 30 or 40 pounds. This weight allows users to place them on a bench for use and tuck them away afterward.
- Portable spindle sanders are handheld tools. While not always useful for smaller pieces, they can be very helpful for sanding curves on large furniture or projects.
Size and Weight
Also consider the spindle sander’s size and weight, particularly if you have a smaller workshop or need more portability.
- Floor-standing units are the heaviest, sometimes weighing more than 300 pounds, but models with locking casters help make transporting them easier. They’re also quite large, standing approximately 3 feet high and extending at least a foot or two in either direction.
- Portable sanders are the lightest option, but working with smaller items can be tricky.
- Benchtop units typically weigh 30 or 40 pounds, so they’re light enough to lift onto a workbench but just heavy enough not to shift while in use. However, they must be set up before each use, and they’re not as effective for sanding curves on larger pieces.
Material
The spindle sander’s material matters. From the base to the work top, some materials are more desirable than others. Floor-standing and benchtop spindle sanders are relatively safe tools, but they’re easier to use if they stay in place on their own. Bases made from metal and dense plastics add a bit of extra weight to the tool. For portable models, the lighter the better, so plastic housings are usually preferred.
Work tops must be perfectly smooth and flat, and the longer they can avoid corrosion, the better. Aluminum and cast iron are excellent choices. A bit of wax across both of these surfaces can keep them smooth and corrosion-free for years to come.
Motor Power
Spindle sanders come in a variety of power ratings, which can make choosing the right model confusing. It’s helpful to think of these power ratings as:
Light duty: These spindle sanders contain motors with horsepower ratings of ⅓ and under. They’re ideal for light work such as craftwork, picture frames, and other small projects.
Medium duty: For most projects, medium-duty sanders, with ⅓ to 1 horsepower, get the job done. They can handle sanding dense hardwoods and larger surfaces.
Heavy duty: At 1 or more horsepower, a heavy-duty spindle sander is the way to go for larger projects. Moreover, they can sand almost any wood imaginable.
Speed
A good spindle sander can cover a large range. Some top-notch models might top out at 1,500 RPMs, while others sanders can reach speeds over 3,000 RPMs.
The best spindle sanders feature adjustable speeds, which can make achieving the perfect edge easier. Slowing down the speed for hardwoods helps reduce the risk of burn marks and wearing out the sandpaper too quickly, while higher speeds can remove a lot of material from a softer wood quickly.
Additional Features
Extra safety and convenience features help set the best spindle sanders apart from the competition. Look for a spindle sander with an oversize on-off switch that’s easy to find and hit if an emergency arises. For increased safety, many of these switches also feature a removable key.
Kits that come with several drum sizes not only offer extra convenience and versatility but also make creating the perfect edge a bit easier. Smaller drums are excellent for tight inside curves, while larger drums make achieving gentler curves a bit easier.
Spindle sanders can create a lot of sawdust, so consider models that include a dust collection port to help keep your work space clean.
Noise Level
When a spindle sander is running, the motor emits a noticeable hum. Finer sandpapers, such as 150 grit, don’t add a lot of noise, but an aggressive sandpaper like 80 grit can increase the noise quite a bit.
In active use, these tools can become very loud; in fact, they can be as loud (or louder) than a table saw, depending on wood species. A lot of variables can affect a spindle sander’s volume, and wearing ear protection is always recommended.

FAQs About Spindle Sanders
Even with all this background and a crash course on some of the top products on the market, you may have some additional questions about spindle sanders. The following is a collection of some of the most frequently asked questions about spindle sanders, so check below for an answer to your question.
Q. What does an oscillating spindle sander do?
An oscillating spindle sander sands curves and edges by not only spinning a drum, but also by moving the drum up and down while it spins. This helps improve the longevity of sandpaper and decreases the risk of damaging the piece.
Q. How loud is a spindle sander?
Some models are very loud. It’s always a good idea to wear ear protection, eye protection, and a dust mask when using a spindle sander.
Q. Do I really need a dust port for a spindle sander?
Spindle sanders can make a lot of dust, so hooking one up to a vacuum or dust collection system is advised.
Q. How do you use a spindle sander?
Simply match the curve with the appropriate spindle, hold the board flat on the work surface, and slide it against the spinning drum to remove material.
