The Best Random Orbital Sanders, Tested and Reviewed
One of the first rules of woodworking is to sand in the direction of the wood grain to avoid creating cross-grain marks that compromise your home project’s finished look. But when a wood-grain pattern changes—for instance, on a parquet floor where grain direction varies from board to board—it’s difficult to sand without causing at least some blemishes.
In these situations, one of the best (and quickest) solutions is to use a random orbital sander—a power tool that features a sanding pad that simultaneously spins and oscillates (orbits) in an ellipse pattern. That magic combination of spinning and oscillating dramatically reduces sanding marks.
There are so many models on the market that choosing the best random orbital sander can feel overwhelming. But, there’s good news: We performed in-depth, hands-on testing with the following models to help point you in the right direction.

How We Tested the Best Random Orbital Sanders
Let’s just say the dust hasn’t settled since our test. We put all of these random orbital sanders through their paces to see what they could do.
First, our test simply consisted of putting each of the sanders together, and all the sanders passed the test. Next, we tested each model with 80- and 120-grit sandpaper against a few pieces of stained pine to determine how quickly they’d remove material as well as how well they’d remove scratches. Finally, we simulated sanding a door or another vertical surface by standing a board on edge.
These tests allowed us to evaluate each model’s speed, comfort, and long-term ease of use. We then gave each model an award based on its strengths, creating this list of the best random orbital sanders.

Product Specs
- Size: 5 inches
- Speed: 7,000; 9,500; and 11,000 opm
- Power source: 18V battery
What We Like
- Cordless portability allows for sanding anywhere
- Adjustable speeds for different materials and aggressiveness
- Comes with a large battery for a longer runtime
What We Don’t Like
- It’s a little tall for a palm sander
When electrical outlets are scarce, or when there’s a need for free range of motion to complete a project, the variable-speed Makita 5-Inch Random Orbit Sander is worth a look. This sander uses the brand’s 18-volt (V) batteries, and it’s available with a 5.0 amp-hour (Ah) battery for up to 65 minutes of sanding on low speed and 32 minutes at high speed. It also comes with a charger and a carrying bag.
This sander features three adjustable speeds, including 7,000; 9,500; and 11,000 opm. While it doesn’t have an extra handle, it is (just) compact enough for one-handed use. Also, this model comes with a dust-collection bag and it uses hook-and-loop 5-inch 8-hole sanding discs.
We realized a few things while testing the Makita. First, we noticed that it was very smooth—the smoothest of all the cordless models. However, we also noticed that it is a bit tall compared to the others. We also found the buttons to be a bit confusing as they’re marked strangely: off is “0” while on/speed change is “1, 2, 3.” While that made speed adjustments a breeze, turning it off was confusing. However, we did like how the dust bag was easy to remove, preventing dust from shooting everywhere like other models.

Best Bang for the Buck
Black+Decker 20V MAX Cordless Random Orbital Sander
Product Specs
- Size: 5 inches
- Speed: 12,000 opm
- Power source: Cordless 20V battery
What We Like
- 12,000-opm top speed
- Affordable price point
- Allows for quick sanding disc changes
What We Don’t Like
- Only 1 speed (but it is fast)
When it comes to sanding on a budget, the Black+Decker 20V Max Random Orbital Sander is tough to beat. This 5-inch sander comes with a 20V 1.5 Ah lithium-ion battery, a charger, and a detachable dust collection system. It weighs just over 3 pounds, and it features a molded-rubber grip for comfort and fatigue reduction.
The Black+Decker random orbital sander utilizes hook-and-loop sanding discs, allowing users to quickly replace a worn disc. While it’s just a one-speed sander (and that one speed is relatively high), quick swapping sanding discs does allow users to dial in the rate at which they’re removing finish or sanding the surface.
For the price, we found it very hard not to like the Black+Decker 20V sander. It might be slightly underpowered and the dust-collection bag is a bit underwhelming, but everything else is spot-on. The grip is comfortable and it has just the right amount of size and weight. It was one of the most comfortable models to use in the vertical-sanding test for those reasons. No, it doesn’t have variable speeds, but it definitely gets the job done.

Upgrade Pick
Bosch 6" Dual-Mode Random Orbit Sander
Product Specs
- Size: 6 inches
- Speed: 3,300 to 7,300 opm
- Power source: 7.5-amp corded motor
What We Like
- Multiple hand positions for better control and comfort
- Turbo mode for aggressive stock removal
- Built-in port for vacuum
What We Don’t Like
- It may be too heavy for smaller jobs
When it’s more about power and capability than portability, shoppers should consider the Bosch 6-Inch Dual-Mode Random Orbit Sander. This burly corded random orbital sander features a large design with multiple hand positions for control and comfort, including a removable handle that mounts on either side as well as a barrel grip and a molded hand pad on top. It uses 6-inch sanding discs and polishing pads.
This model features two modes: a random orbital mode and a turbo mode. The turbo mode maxes out at 7,300 opm and removes stock at five times the rate of the basic mode. Also, this sander features a built-in vacuum port to which users can hook up their shop vacuums or shop dust collection systems. It is a little expensive, but its capabilities make up for the price.
Here’s what we think of this random orbital sander from Bosch: It’s a beast. While the top speed might seem low, it has a big sanding disc and lots of torque. And, despite its power, it has a slow-start feature that prevented it from jumping in our hands upon start-up. It’s incredibly aggressive in Turbo mode but very easy to handle in standard mode. It might be a bit heavy for smaller jobs, but the weight helps it run smoothly and minimizes vibration (not in Turbo mode, though!).

Best Corded
DeWalt 5" Single Speed Random Orbit Sander
Product Specs
- Size: 5 inches
- Speed: 12,000 opm
- Power source: 3-amp electric
What We Like
- 12,000-opm high-speed sanding
- Great dust-bag design
- Lightweight and compact
What We Don’t Like
- Single-speed only
For those looking for a random orbit sander with continuous corded power, check out the corded DeWalt Single Speed Random Orbit Sander. The 5-inch sander comes with a detachable dust-collection bag for catching sawdust. It also comes with a soft carrying bag to keep things organized.
This 5-inch 4-pound sander’s 3-amp motor is designed for reduced vibration while also offering up to 12,000 opm of speed. This palm sander features a rubberized palm grip to further reduce vibration and increase comfort, making the tool easier to use over the duration of a project. However, do keep in mind that this sander has just one speed (and it’s a high one), so be sure to use the correct sandpaper at all times.
To be honest, we were kind of skeptical about comparing a single-speed random orbital sander to other models with more features and flexibility. However, this model from DeWalt proved more than worthy during our test. First, it felt lighter than the other corded models, and it was quite comfortable in hand thanks to its compact and low-profile design. The dust-collection bag worked well, and we found emptying it was very easy as it has a coiled spring inside that collapses to push dust out. The bag also has a collar that twists into place for a secure fit and easy removal. And while it only has one speed, that speed will be plenty for most users.

Best Cordless
DeWalt Cordless Variable-Speed Random Orbital Sander
Product Specs
- Size: 5 inches
- Speed: 8,000 to 12,000 opm
- Power source: 20V battery (sold separately)
What We Like
- Adjustable speeds for controlling aggressiveness
- Compact and lightweight design for control
- Offers cordless portability
What We Don’t Like
- Ours had a loose shroud
Any DIYers, woodworkers, or cabinetmakers—professional or weekend warrior—should check out the DeWalt Cordless Variable-Speed Random Orbital Sander. This 5-inch cordless sander features a compact design for ease of use as well as variable speeds between 8,000 and 12,000 opm for controlling aggressiveness on different surfaces. It also features a one-handed locking dust bag that allows the user to empty it fuss-free.
This sander utilizes 5-inch 8-hole hook-and-loop sanding discs, allowing for quick changes between grits or when one pad runs out. While this particular model doesn’t come with a battery or a charger, it’s compatible with the brand’s 20V Max battery lineup. This allows users already invested in DeWalt tools to take advantage of their stock of batteries.
The DeWalt cordless random orbital sander did not disappoint during our test. This model features DeWalt’s collared dust bag that is not only easy to take on and off but also simple to empty thanks to the coiled spring inside. We also liked this model’s size as it was light and compact but still provided lots of power when needed. It was also fairly smooth during use; however, the rubber shroud around the disc on our model was loose and rubbed the disc, but all it required was some fidgeting to get it back in place.

Best Pneumatic
Dynabrade 5" Non-Vacuum Random Orbital Sander
Product Specs
- Size: 5 inches
- Speed: Max of 12,000 opm
- Power source: Air
What We Like
- Smooth operation
- Lightweight and easy to maneuver
- Lots of accessories available
What We Don’t Like
- Doesn’t come with a hook-and-loop pad
For anyone creating a workshop of pneumatic tools, the Dynabrade 5-Inch Non-Vacuum Random Orbital Sander will make a fine addition. This model utilizes air pressure instead of electricity, allowing users to take advantage of their compressors while leaving an extension cord on the shelf.
Weighing in at just 2.04 pounds, the Dynabrade random orbital sander is easy on the hands and lightweight enough to use for extended periods. It features a five-blade rotor for high-speed sanding capability (up to 12,000 opm), the speed of which changes with the air pressure exerted by the compressor. It also features an ergonomic palm grip and fits a standard ⅜-inch air compressor hose. Do keep in mind that it’s important to have a large compressor on hand, as air-powered random orbital sanders use a lot of air.
Dynabrade’s 5-inch random orbital sander is highly flexible, and that’s something we really liked about it. While our model didn’t come with a hook-and-loop pad for standard sanding discs, the vinyl-faced pad intended for pressure-sensitive discs contoured when we needed it to and then flattened out for straight, level sanding surfaces—just as one might expect for a sander designed for automotive use. While it was slightly loud (all air-powered tools are), it ran smoothly and felt substantial in hand despite being so lightweight.
