This is because it utilizes a round sandpaper disc to sand in rotary as well as orbital motion. By blending these two motions simultaneously for sanding, the tool alleviates swirl marks, which otherwise spoil a fine finish.

With this tool, you can rapidly sand the wood with a whirl-free finish by spinning the disks as well as moving them simultaneously in small ellipses. This gives you the power of a belt sander with a mildness that prevents damage to delicate pieces. Such a sander can sand quite smoothly as well as quickly, with the bonus of random action, leaving only a few sanding marks, unlike a sheet sander, palm sander, or a belt sander.

The tool is capable of sanding the socks off your former vibrating sander while removing furniture paint, cleaning up in between finish layers, and preparing novel molding. It is also possible to smooth as well as clean metal or a composite material such as a solid countertop.

Working of a Random Orbital Sander

Fein MSF636-1 3.7 Amp 6-Inch Random Orbit Sander with Vacuum AdaptorThe ability to sand in a fully random orbit at the maximum speed of up to 25,000 Revolutions Per Minute (RPMs) is the unique feature of these sanders. Such motion enables the tool to leave a clean, smooth finish. The motion is also responsible for making such a sander versatile.

The sandpaper disc turns in a circle, while the complete pad loops in an elliptical motion. This mechanism ensures that not a single abrasive particle goes twice along the same path. As a result, you obtain a swirl-free finish despite sanding across the grain.

Although the random orbits perform more rapidly than vibrating sanders, they are incapable of removing much material aggressively. In case you want the latter, consider having a disc sander for a curved surface and belt sander for a flat one.

Random Orbital Sander versus Sheet Sander

Random orbit and sheet sanders are both types of orbital sanders. Each of them has unique pros that make it more efficient for certain tasks than the other. An orbital sheet sander is easy to use and helps in finishing a construction project. It comes with several features such as various grip styles, low vibration, low noise level, electronic speed controls, and dust elimination.

You can even find different sizes of these sanders. Large ones utilize almost half a sheet of sandpaper, while small ones employ 1/4 or 1/6 size sandpaper sheet. While using this tool, you do not go across the wood’s grain, but go with it so that there are no sanding spots to damage the workpiece.

On the other hand, a random orbital sander sands the pieces randomly and offers a smoother finish without any sanding spots. It features an offset drive bearing for making the pad perform circularly as well as elliptically around a wood surface.

A plus point of this sander is that you are not confined to only grain sanding, as in the case of a sheet sander. You are free to sand all over the surface in any direction and yet achieve a striking outcome.  Keeping these facts in mind, you should accordingly make the right choice from the two types of sanders.

Random Orbital Sander versus Belt Sander

Both of these tools are useful for rapid sanding. However, a belt sander is bigger and faster than any orbital version. It also can be used to sand any larger or flatter wooden surfaces such as a worktop or floor. However, a belt sander leaves behind directional markings and that it is not feasible on more intricate pieces such as a chair, and smaller wooden items.

How to Choose the Best Random Orbit Sander

Having a random orbital sander of good quality in your workshop will make finishing tasks for almost any furniture project much easier, whether it is making a new one or refinishing an existing one. Such a sander is super easy as well as quick to use even if you are a starter. However, it might not be that easy to choose the best model because there are several varieties of such sanders to choose from.

A few types are better for a few tasks, while others are designed for efficiently performing the remaining jobs. What does this statement indicate? Well, it tells that the buyer needs to know which variety or style is suited for which task and accordingly choose a model as per the desired features, specifications, and set a budget. In simple terms, you need to consider a few factors and map them to your needs, for judging which model is the best orbital sander for your kind of work.

Thus, the essential step before mapping the buying factors is to identify your needs or requirements. For this purpose, you need to answer the following questions:

  1. Are you using a sander for the first time?
  2. Will you be using the tool for professional or hobby purposes?
  3. What types of materials or surfaces will you be working with, frequently?
  4. Do you need a portable or corded model?
  5. Which options or features are necessary for you to have?

Replying to these queries aids you in narrowing down your choices to reach up quickly to the right random orbital sander. This is because you know for what you will use the tool. Well, let’s now explore the buying factors.

What to Look for in a RO Sander?

Factor 1: Types

In terms of style, there are different types of random orbital sanders. Although all of them perform superbly, each one is a bit different. You need to recognize the differences before choosing the best random orbital sander. Each of these sanders is capable of rendering great performance for most tasks. You just need to ensure that the chosen one best suits your needs. Here are the three types of random orbital sanders.

  • Palm Grip: Focusing on the name, this kind of sander is quite compact to fit into your palm for an easy and comfortable hold. Also known as the palm sander, this orbital sander is ideal for finishing fine surfaces such as window frames. The tool is even better for sanding small or narrow areas where other types of sanders cannot reach or fit. It ensures more than desired control over the sanding area despite being small.
  • Right Angle: This kind of random orbital sander is ideal for those who are looking for much power. It features gears that link the sanding pad to the motor. Although the overall speed is usually a bit slower, such a sander is capable of being pressed harder against the surface, without any risk of damage. As a result, a right angle random orbital sander is ideal for discarding tough substances, such as paint or glue from a piece.
  • Large Inline: This kind of sander is ideal for big sanding projects demanding upscale features that this tool offers, without fail. Such a tool comes with the most powerful motor running at a variable speed. You need to use both your hands to run this sander, but you obtain much control over the sander’s speed.

Factor 2: Brands

Well, it is rational to consider a brand always when you have to buy a sander. Doing so always assures quality, efficient performance, and good warranty and after-sale service. For buying the best random orbital sander, the top brands that you should consider are Festool, Bosch, Black & Decker, DeWalt, Clarke, Dynabrade, Makita, Milwaukee, Porter-Cable, Hitachi, and Ridgid.

Control is dictated by how the tool operates. Having a jumpy or wobbly model is the last thing anyone would want. If you see these unwanted moves, the cause lies in the orbit diameter, the level of aggressiveness, motor, and gearing. Eliminating the risk of these moves is the smoothest collection of Festool.

The random orbital sanders of this brand seem to have a smaller orbit diameter and are least aggressive. One of its latest models finishes a surface beyond 180- or 220-grit sanding. Most of its random orbital sanders are perfect for intermediate sanding and rapid stock removal. They are convenient and lighter for incessant sanding jobs.

On the other hand, Ridgid models have a larger orbit diameter and perform aggressively, although without wobbling. Bosch models are innovative but are tougher to control. Craftsman sanders are also tough to control due to the large diameter of the orbit. The Bosch models might be a bit wobbly but are pretty balanced.

Dynabrade models are famous for their ergonomically designed handgrip and lightweight design. They are quiet in operation and ensure proper control. Porter-Cable models are known for their copious sanding power, low-vibration mechanism, and dual plane capabilities.

Factor 3: Motor

This is a vital factor to consider, as it converts electricity into motion. Most random orbit sanders have AC motors, also known as series or universal motors. By taking an input power between 200 and 750 Watts from the power outlet, these tools usually produce less power measured in Watts.

The power output is considerably less at the sandpaper than the input power, because of the internal components’ efficiency. Usually, high-quality models are efficient enough to consume less input power for generating the same power output. Thus, always look for output power value, although the models come labeled with input power values.

You also need to consider the motor size, as it finally decides the amount of power in the tool. The more the size, the more powerful the motor is to apply more speed. Such a motor also lasts longer. Another aspect to consider is Orbits Per Minute or OPM, which indicates how rapidly the tool can vibrate. When the tool vibrates more rapidly, the sanding operation is quicker and more amount of wood is discarded.

On average, you will find most models having a motor of 3-5 amps and 7,000 – 12,000 OPM. All these models are promising for most projects. Many of these models are corded, but you can choose a cordless version for ensuring portability at the cost of less power than the former ones. For heavy use, a pneumatic version is ideal, although it shall be relatively costlier. These versions are driven by compressed air and are suitable for industrial or factory tasks.

Factor 4: Size

Although the random orbital sanders are available in different sizes, most woodworkers choose the 5-and 6-inch ones. This measurement indicates the disk diameter, which is located at the tool’s bottom.

A few models will allow swapping the pad size to utilize a range of disk sizes. You can do so with the help of an Allen key (a hexagonal cross-section tool for driving screws and bolts with a hexagonal socket at the head) located at the base’s bottom. A majority of random orbital sanders come with a hook and loop paper changing system, which means now there is no need for messy adhesive sprays.

Factor 5: Dust Collector

A random orbital sander produces a huge amount of dust. Therefore, almost all modern versions come with a built-in dust collecting mechanism that takes the dust into the small holes of the sandpaper. If a vacuum device is present, the tool collects all the debris into the attached container

If the useful vacuum is already there, you need sandpaper with a special diameter and style suiting to the feature. Each random orbital sander needs its sandpaper. For removing the debris while sanding, the sandpaper aligns nicely with holes in the base pad of the sander.

Factor 6: Sanding Disk, Sandpaper, and Sanding Plate

You can judge the suitability of a sanding disk for the tool by evaluating it based on two criteria, namely, its diameter and number of holes within. Proper matching of holes from sandpaper to tool allows efficient operation of the dust extraction feature.

After matching them up, you need to choose the grade as per the undertaken application. The grade is indicated by the number of sand granules per square inch of sandpaper. A lower grade indicates coarse, while a higher grade signifies finer sand granules. For example, for metal and wood, you can choose a fine, medium, or coarse grade sandpaper, while for glass and ceramics, you can even choose a polish-sanding grade.

Coarser ones are ideal for removing a lot of material, while finer ones are for applying the final sanding process before applying the final finish. It is recommended to start with a coarser grit of sandpaper and then follow up to a finer one, so that you move from rough sanding to finer finished sanding, in the beginning. You can choose the right grade as per the sander model and surface you will be working on.

You can consider purchasing sanding disks of different grit sizes, or in a combination of sizes. A majority of packs will have circular disks that you can effortlessly attach to your tool. A sanding disk is fitted to a sanding plate that oscillates for sanding. Usually, the disk is a 5-inch diameter area of sandpaper and attaches to a foam rubber pad. It has a round pattern of six to eight holes affixing to the dust accumulation holes of the pad. You can buy such disks with different grit levels, including low to fine grades (60 to 220).

You can fit the disk to the plate in one of the two ways, namely, hook-and-look system (Velcro) and peel-and-stick Pressure Sensitive Adhesive (PSA). Of the two, the most common one is the Velcro one on portable sanders, and you can easily get cost-efficient disks for the same. However, it is subject to wear and consequently replacement.

You can choose either a softer or harder plate. A softer one is for sensitive and polishing sanding of even a curved surface, while a harder one is for a flat surface demanding more sanding capacity. Nowadays, almost all random orbital sanders have a universal plate that can sand all normal applications.

Factor 7: Vacuum

Most random orbital sanders indeed have an attached canister or a dust bag to ensure cleanliness while sanding. An onboard dust collection in this way is good, but the most effective method of keeping dust away is connecting the tool to a shop vacuum of good quality. Therefore, check out for a compatible connection area on the tool you choose, which can go with the standard vacuum sizes, such as 1.25″, 1.5″, and 2.5″.

Factor 8: Prompt Paper Change

It is useful to look for how easy and fast a random orbital sander can change the sandpaper. While at work, the sander always outlives the sandpaper. As per the paper’s grit, it can wear out quite rapidly. Thus, it makes sense to choose a model that facilitates a simple and quick change. The hook and loop mechanism is the most common method of affixing sandpaper, as it is effortless and fast by peeling off one and applying the next.

You can use this mechanism in case you can work a zipper. If the sandpaper has not worn out, the hook-and-loop mechanism allows reusing the sheet. Most sanders come feature such a mechanism of eight holes.

An assortment of paper types /sanding frits is available for a variety of sanding jobs. While a few shall loop over the belt, the rest shall stick to the sander’s bottom through their adhesive rear. Regardless of what you prefer, just ensure that you can change the paper fast for keeping disruptions away.

Factor 9: Variable Speed

The transmission or gearbox determines the speed of the tool, which ranges from 1,600 to 26,000 OPMs. The bigger this range is, the greater are the capabilities of the tool. Therefore, it is best to choose a model with variable speed settings.

Control over the tool and its sanding procedure largely determines how smooth the finish will be. The key to a smooth finish is a control whose critical aspect is variable speed. This setting allows increasing or decreasing speed according to the type of material you are working on.

Slower speed range is ideal for materials like veneer for alleviating the probability of sand-through as well as for a smooth and soft finish. However, random orbital sanders having variable speeds are a bit costlier than those without it, although that additional cost is worth the control you achieve. After all, the freedom to control and adjust the speed allows using the tool exactly as you desire.

Factor 10: Sander Grip

It is rational to choose a sander that will feel comfortable and non-slippery in your hand. Your fingers can easily wrap around the tool and switch it on or off. At the same time, the tool should not be so heavy to hold. A few models come with a soft grip design for giving you extra comfort. You need to ensure that the tool is more comfortable to use and hold so that you can use it longer without experiencing cramps or getting tired.

It is a bit tough to gauge how a tool will feel in hand. Nevertheless, there are several variables to check out, such as hand strength and size. Along with the right size, check out for a soft over-mold on the grip, which helps in alleviating both fatigue and vibration during extended work time.

Random orbit sanders have either a single or dual handles. It is advisable to get a model with dual handles, as it delivers relatively more control while at work. You can easily remove the second handle if you need to work close to a wall. The smaller palm grip sanders come with one handle, but the bigger ones can have either one or two handles. You can still run them with one hand.

Factor 11: Sealed Switch

Sanding produces a lot of dust that can reduce the lifespan of the tool. However, if you choose a model with a sealed switch, you can avoid this issue. Such models prevent problems caused while turning the tool on or off because of dust accumulating in the switch area.

Factor 12: Balance

A nicely balanced sander is essential for using the tool comfortably. At the same time, you should look for a model that does not vibrate tremendously, as such vibrations can lead to fatigue, especially during prolonged work. Vibration also affects finish and accuracy, particularly on finer pieces. As a rule of thumb, the lesser the vibration, the better will be the finish, and the lesser will be the damage or scratches.

Factor 13: Power Cord

If you wish to buy a corded model, ensure that the cord is not too short of making you purchase an extension cord. Therefore, choose the one that has a long cord.

Factor 14: Portability

Choose a lightweight model with a good carrying case if you wish to take the random orbital sander to another shop or anywhere else. Most sanders come with a good carrying case. If not, you can easily buy one such case that can even accommodate its cord.

Factor 15: Other Features

Do consider having a trigger lock to keep the tool locked when it is in ‘on’ state, without keeping the trigger pushed. As a result, your hands are now free to control the sander. Another useful feature to look for is pad brakes that keep gouging away when the material is heavily notched upon. Additionally, look for a model that allows quick and easy tracking adjustments through knobs or screws.
