What is a Random Orbital Sander?

If you already know what belt sanders and orbital finishing sanders are, you shouldn’t’ have difficulties identifying the best random orbital sanders. Basically, these devices have the compact housing designs of a finishing sander but their sanding pads are round in shape. This is contrary to the orbital finishers whose sanding pads are square-shaped. Another notable difference in a random orbital sander is that it has the aggressiveness of a belt sander and the fine finishing feature of an orbital finishing sander.

With that in mind, a typical random orbital sander will have its pad rotate in “random orbits,” albeit with a circular motion. In addition, this pad rotates simultaneously to enable a woodworker to eliminate stocks smoothly. A good random orbit sander is also able to eliminate swirl and leave an impressively fine finish. Note also that because of their random sanding action, sanders are not sensitive to the direction of the wood grain, thus enabling them to sand two or more pieces of wood that are combined together.

Design

As already mentioned, most sanders are handheld, often featuring a single hand. When it comes to size and weight, the device’s approximate 5 pounds and measurements that do not exceed 6 inches. However, you can also find a random orbital device with a barrel-grip or D-handle.

Disc shape

These devices either feature pressure-sensitive adhesive abrasive discs or hook and loop disks. The biggest difference among the two is that the hook and loop disc is faster and easier to remove, while the former are cheaper but more difficult to change. Modern devices also feature a dust collection feature that sucks dust through a vacuum and collects it to a bag.

Finally, random orbital finishers are designed to handle multiple tasks, which is why most of them also feature variable speed control systems. There are also not expensive, and range between $50 and $250.

Types of Orbital Sanders

When you are a DIY person, or any average woodworker, there is a time when you will need to sand a surface. And in these modern times, you would be misinformed to use rough sand paper when electric sanders are so cheap and efficient.

There are multiple sanders you could choose from, but orbital sanders are the most common among them. So what makes them good? Read below and also learn the different types of orbital sanders you should consider buying.

Orbital Finishing Sander

A typical orbital finishing sander is small, handheld, and quiet in operation. You can find these devices in almost any retailer that trades woodwork tools, and there aren’t expensive either.

However, their expensive nature should suggest something to you; they aren’t the best. On average, a good orbital finishing sander will align surfaces accordingly, but won’t remove stocks and debris efficiently.

The devices also go by the name quarter-sheet sanders, because they accommodate 9*11 inch sized sand papers. The sand papers are in turn held safely by clamps underneath the tools’ flat pad. Note however that these pads are square-shaped even if they rotate in a circular motion.

Random Orbit Sander

If you are reading this, you have probably already gone through our six reviewed random orbit sanders. But to refresh your mind, a random orbit sander has a circular shaped sanding pad. They are more aggressive compared to orbital finishing sanders and thus can remove stocks and achieve smooth finishes as well. One of the biggest advantages of a random orbital sander is their versatile nature.

On average, you could use a strong random orbital sander to dispel stocks from severally connected pieces of wood, fine-tune large doors and convey it home for your DIY projects with ease.

Detail Sanders

Ideally, a detail sander is an orbital sander with triangular-shaped plates, small for use in confined areas and corners where normal sanders can touch. They mostly use sticky sandpapers, they are cheap and work well as fulfilling sanders to professional woodworkers. Since they are only good for windows or corners, these types of sanders are really cheap, mostly priced under $50.

Rectangular Pad Orbital Sanders

These devices are often not different from normal sanders, except for the fact that they have pads shaped in a rectangular design. Other than that, they are portable, efficient, and as reliable as any other good orbital sander.

What to Look for in the Best Random Orbital Sander?

Best Random Orbital Sander

Instead of juggling between the many types of sanders in the market today, isn’t it just better to know what makes up the best sander and buying it? After all, there is a high chance that you probably only care about the efficiency, convenience, and price of a sander, right? Okay, there are a few more factors you should consider before buying the right sander for your job. Below we have compiled a detailed list to guide you through the buying process.

Motor Power

Typical orbital sanders operate by use of a motor. On average, a good sander should have a motor that can produce at least 3amperes worth of power. The power produced by the motor plays a great role in determining the speed at which the tool can rotate, which in turn reflects in the overall machine’s efficiency rate. Slower rotating sanders definitely can’t handle the tough jobs a high rotating device can and this is a factor you should keep in mind.

Comfort Level

Sanding is often not a fun job. When you are a professional, you could actually take half or a whole day working on different sanding jobs. With this in mind, you may want to buy a sander with the best handles and grip functions. Fortunately, most of the modern orbital sanders in the market have anti-slip grip handles that can be held from multiple locations.

This makes it easy for you to handle small and big doors alike without getting hand cramps or experiencing a lot of fatigue. Comfort also comes in how well you can use the sander while tackling corners or hard to reach areas. Consider these factors can then settle for the best tool you can get.

Dust Collection System

Again, most of the modern orbital sanders do come with a dust collection system. Don’t ignore to check every model you plan to buy, though. A good sander often features a vacuum that sucks debris and dirt into a bag that can later be removed. Others simply sucks dust directly with holes built from their sanding pads.

The dust is then directly into a dust canister that is attached to the machine. But alongside the dust collection system, take note of the machine’s ability to protect itself from excessive dust. Go for a machine that doesn’t hold the dust, as this could reflect in a shorter service life.

Variable Speed Settings

A sander with a controlled speed setting not only helps save your energy while working, but it also prolongs its service life. You are also able to maintain the sandpapers because the device can rotate slower or faster depending on the application at hand. Such sanders are also great for versatility because you can remove paints with them or apply smooth finishes without affecting your materials.

Quick Sand-paper Changing system

If you sand at a professional level, you probably use several sandpapers before completing your job. And to help save on your time, you may want to buy a device that you can easily swap sandpapers for a more effective working experience. When you buy a hook and loop disk sander, changing papers will always be fast and effortless. Sometimes it takes five seconds or less to swap papers from such a sander, and this further saves your time.

Long Power Cord

It may not look like a big deal, but you will realize the need for a sander with a long cord when handling big doors and tables. As such, try to settle for a device with a longer power cord instead of buying a machine that will force you to invest more in extension cords.

Light

If possible, settle for the lightest yet most efficient orbital sander you can find. It just helps to have a light device, as this will reduce the fatigue rate to a great extent. But along the lightness, ensure that you buy a device constructed to last for long.

Benefits of a Random Orbital Sander

Although modern sanders aren’t 100% effective at handling contoured surfaces, they are undoubtedly great machines for removing stocks and making surfaces smooth. When tackling professional jobs actually, you can’t make it without a random orbital sander. And truth be told, sanders don’t disappoint. They also have their own unique benefits, some of which include:

Excellent Stock Removers

If you can find a great random sander, you may never get disappointed when it comes to eliminating stocks. Their small circular shaped pads and strong motors are actually built to remove even swirls, and in the end providing you smooth surfaces. This is actually a unique benefit to random orbit sanders, as other machines find it hard to eliminate swirls.

Provide Smooth Finishes

When you buy the best random orbital sander, you get services often provided by orbital finishing sanders and belt machines. To be specific, these devices will achieve the great smooth finishing levels the best finishing sander can achieve and eliminate stocks as efficiently as possible. And if you can find a device with controlled speed settings, you will be able to get excellent results even from contoured surfaces.

Feature Easy to change Hook and Loop disks

Most sanders feature hook and loop disks which can be changed in as quick as 5 seconds. This helps you save a lot of time and concentrate more on sanding than in changing papers. There are also not demanding in maintenance expenses, especially if you only use your sander for simple DIY jobs.

Efficient Dust Collection systems

Most of the modern random sanders in the market today are great with controlling dust and debris. They are also designed to eliminate as much debris as possible, and in the end helping prolong their service life. Typical sanders have holes that suck dust and collect it into a dust canister, while others have built-in vacuums to suck debris. In the end, you are able to operate comfortably without being affected by dust at your workshop.

Comfortable and less tiring

Finally, sanders have small and light designs that feature comfortable handles. In most cases, the devices weigh less than 5 pounds and come with slip-free grip handles that do not cause cramps on your hands.

Conclusion

Although sanders are not perfect sanders, they are at least better in performance than most other types. And if you can find the best random orbital sander actually, you could be in for the comfortable, versatile, and efficient benefits they provide. In addition, most of these devices are inexpensive despite helping you to eliminate stock and achieve smooth surfaces. Still, there are many more reasons to love these machines.
