What is a random orbital sander?
An orbital wood sander is a power tool in which the sanding pad makes random-orbit movements. It is a combination of the speed and belligerence of a belt sander and the ability to give an excellent finish that an ordinary orbital wood sanders can deliver. There are three types: air powered, electric powered, and the ones that roll on the floor called floor orbital sanders.
How does it work?
Unlike belt sanders that can only move back and forth or ordinary orbital sanders which can only perform simple circles, the random orbital sanders for woodworking moves in random orbits. That means that it vibrates in tiny ellipses, but the disk also spins in circles. This process is completed to ensure that not a single piece of erosive material roams the same path during one rotation.
As a result of its movement, the random orbital sander can be used for stock removal, as well as for extra smooth sanding.
Mostorbital wood sanders come in a one-handed, palm-grip shape. You can easily hold them in your hands, which is why they are more popular than the others. However, you can also find D-handle or barrel-grip random orbital sanders.
A random orbital sander is extremely helpful if you like working with wood. It shortens the time that you usually spend on sanding, and the wood has an excellent finish at the end. Other than that, this power tool has other advantages:
- It comes with a dust collection bag or dust port (in case you want to connect it to vacuum). This feature will spare you from cleaning the space where you work, as well as sparing your lungs from all the dust. However, in spite of this feature, I still recommend the use of a dust mask.
- Spare disks are easy to replace. You can use pressure sensitive adhesive to apply the new pad, or you can use the hook and loop system (Velcro).
- The random orbital sander comes with 5 or 6 inches pads, but if you want to use it for your DIY project, a 5-inch pad is more than enough.
Pros and Cons
Since it is a power tool that makes your DIY projects easier, the best orbital sander for wood has many pros. Other than the obvious, this tool doesn’t leave swirl trails behind. That is thanks to the orbit movements it makes. Also, the direction of the wood grain will make no difference in the sander’s movements. This feature comes in handy when you want to sand two or more pieces of wood which have been joined.
As long as the cons go, there isn’t much to say other than that the random orbital sander is not so fast as a belt sander. Also, it is a little harder to control than a regular orbital sander.
Having a porter cable orbital sander of quality that is high in your workshop will do the finishing job for just about any furniture job much simpler, while it’s making a fresh one or refinishing an existent one. Such a sander is fast to make use of even in the event you are a starter in addition to simple. Nevertheless, it may not be simple since there are many varieties of such sanders to pick from to decide on the most efficient version.
A couple of types are better for several endeavors, while some are made for performing the remaining jobs. What exactly does this statement suggest? Well, it tells the buyer must understand which fashion or variety is suited for which job and so select a version according to the desirable characteristics, specifications, and establish the budget. Essentially, for judging which model is the very best orbital sander for your form of work you should take into account a few variables and map them to your needs.
Types of Sanders
When it comes to fashion, there are various kinds of random orbital sanders. Each one is somewhat different although all of them perform superbly. Before selecting the top random orbital sander, you should understand the differences. All these sanders are efficient at rendering excellent performance for the majority of jobs. You simply need to make sure that the chosen one best suits your needs. Here is a random orbit sanders comparison test we’ve set for this 3 types.
This form of the sander is very streamlined to fit into your palm for a straightforward and comfortable hold. Also called the palm sander, this orbital sander is well suited for finishing fine surfaces for example window frames. The tool is for sanding small or narrow places where other varieties of Sanders cannot reach or fit better. Despite being little, it ensures more than wanted control over the sanding area.
This sort of random orbital sander is well suited for those trying to find much electricity. It features gearing that link the motor and the sanding pad. This type of sander is capable of being pressed against the surface, with no danger of damage despite the fact that the total rate is somewhat slower. Because of this, a right angle random orbital sander is well suited for losing tough materials, like paste or paint from a bit.
This form of the sander is well suited for sanding jobs that are large requiring upscale characteristics this tool offers, without fail. Such a tool includes the most powerful motor running at a rate that is varying. You get much control over the sander’s rate although you should make use of both your hands to run this sander.
Choose the Best Brands
Well, it’s reasonable to think about a brand consistently when it’s necessary to purchase a sander. Doing so constantly guarantees efficient operation, quality, and the good warranty and after-sale service. The top brands which you need to consider are Festool, Bosch, Black & Decker, DeWalt Orbital Sander, Clarke, Dynabrade, Makita, Milwaukee, Porter-Cable, Hitachi, and Ridgid for purchasing the very best random orbital sander.
The manner where the tool works dictates management. Having a wobbly or jumpy version is the final thing anyone would need. In case you see these unwanted moves, the cause can be found in the degree of aggressiveness, the orbit diameter, motor, and gearing. Removing the threat of these moves is the smoothest set of Festool.
The random orbital sanders of this brand are competitive and appear to get a smaller orbit diameter. One of its latest versions finishes a surface beyond 180- or 220-grit sanding. Most of its arbitrary orbital sanders are ideal for fast stock removal and intermediate sanding. They’re lighter and suitable for sanding occupations that are incessant.
On the flip side, Ridgid versions appear to get a bigger orbit diameter although without wobbling, and perform more sharply. Coming to the Bosch versions, they can be progressive but are possibly more demanding to command. The latter aspect is, also, related to the Craftsman sanders, which is anticipated as a result of the large diameter of the orbit. The Bosch versions may be somewhat wobbly but are relatively balanced.
Dynabrade versions are well-known for their ergonomically designed lightweight design and handgrip. They ensure appropriate management and are quiet in operation. Porter Cable versions are famous for their copious sanding electricity, low-double airplane abilities, and vibration mechanism.
It’s true that random orbital sanders have a dust bag or an attached canister to make sure cleanliness while sanding. An onboard dust set in this manner is not wrong, but the best way of keeping dust away is joining the tool to a store vacuum of high quality. So, check out for a compatible connection place on the tool you decide on, which can go together with the standard Hoover sizes, including 1.25″, 1.5″, and 2.5″.
It is an important factor to take into account, as it converts electricity into movement. AC motors have been by most random orbit sanders also called universal or string motors. These tools typically generate less power by taking an input signal electricity between 200 and 750 Watts from the electrical outlet.
Due to the internal parts’ efficiency, the power output is significantly less at the sandpaper about the input signal electricity. High-quality versions are efficient enough to use up less input signal power for creating the same power output. Even though the versions come labeled with input power values so, constantly search for output power value.
As it eventually determines the number of electricity in the tool, in addition, you have to think about the motor size. The more the size, the more stable is the motor to use more rate. Such a motor tends to last longer. Another aspect to take into account is OPM or Orbits Per Minute, which suggests how fast the tool can vibrate. The sanding operation is quicker, and much more quantity of wood is lost when the tool vibrates quickly.
On an average, you’ll find most versions having a motor of 3-5 amps 12,000 OPM. – And 7,000 All these versions are promising for most jobs. Some these versions are corded for ensuring in the price of less power compared to the former ones. However, you can pick a cordless variant. For heavy use, a pneumatic version is perfect even though it shall be comparatively more costly. Compressed air drives these variations and is fit for factory or industrial jobs.
Size and Portability
Despite the fact that the random orbital sanders are obtainable in various sizes, most woodworkers select the 5-and 6-inch ones. This measurement indicates the disc diameter, which is situated in the tool’s underside.
Pick a version that is lightweight with great carrying case should you desire to choose the random orbital sander to a different store or elsewhere. Most sanders come with a carrying case that is good. Otherwise, it is simple to purchase one such case that may also adapt its wire.
A couple of versions will enable swapping the pad size to use a variety of disc sizes. You can do so with the aid of an Allen key (a hexagonal cross section tool for driving screws and bolts using a hexagonal socket in the head) situated in the foundation’s underside. Most arbitrary orbital sanders come with a hook and loop paper altering system, which means there isn’t any demand of dirty adhesive sprays.
A nicely balanced sander is essential for utilizing the tool. At the same time, you need to look as such vibrations may bring about exhaustion, particularly during lengthy work for a model that will not vibrate extremely. Precision and finish additionally influence, especially on finer bits. As a guideline, lesser the shaking, the better will be lesser, and the finish will be the damage or scrapes.
A random orbital sander generates a lot of dust. Thus, nearly all modern variants come with built-in debris gathering mechanism that requires the dust into the tiny holes of the sandpaper. If a vacuum apparatus is present, the tool collects all the debris into the container that is connected
In the event the Hoover that is useful is there, you need sandpaper with specific diameter and fashion satisfying to the attribute. Each random orbital sander wants its sandpaper. The sandpaper aligns with holes in the foundation pad of the sander for removing the debris while sanding.
Prompt Paper Change
Looking for quick and simple the sandpaper can alter is beneficial. While at work, the sandpaper is consistently outlived by the sander. According to the paper’s grit, it can wear out fairly quickly. So, it seems sensible to take a model that facilitates a rapid and straightforward change. The hook and loop mechanism is the most frequently encountered approach to affixing sandpaper, as it’s exceptionally straightforward and speedy by peeling one off and using the next.
It’s possible for you to take advantage of this mechanism in the event you’ll be able to work a zipper. In the event the sandpaper hasn’t worn out, the hook and loop mechanism enables reusing the sheet. Most sanders attribute this type of mechanism of eight holes.
A variety of paper types /sanding frits is accessible for an assortment of sanding occupations. While the belt shall loop over, the remainder shall follow the sander’s underside through their adhesive back. No matter what you favor, simply make sure that you’re capable of shifting the paper quickly for keeping interruptions away.
Sandpaper, Sanding Disc, and Sanding Plate
By assessing it upon the premise of two standards correctly, its diameter and amount of holes in it are possible for you to judge the suitability of a sanding disc for the tool. Appropriate matching of holes from sandpaper to tool enables efficient functioning of the dust extraction attribute.
After matching them up, you should decide on the level according to the use that is undertaken. The amount of sand granules per square inch of sandpaper indicates the score. A lower level signals rough, while a higher level signifies fine sand granules. For instance, for wood and metal, you can select medium, a fine, or coarse grade sandpaper; while for ceramics and glass, you can also pick a polish-sanding level.
Rougher ones are perfect for removing lots of stuff, while finer ones are before applying the last finish for implementing the last sanding procedure. It’s recommended to start with a rougher grit of sandpaper then follow as much as a fine one, in order you go from rough sanding to finer sanding that was ended, in the beginning. It’s possible for you to select the best mark according to the sander model and surface you are going to be working on.
It’s possible for you to think about in a blend of sizes, or buying sanding discs of different grit sizes. Most packs will have annular discs you could attach to your tool. A sanding disc is fitted for sanding to a sanding plate that oscillates. Normally, the disc is a 5-inch diameter area of sandpaper and attached to a foam rubber pad. It’s a round pattern of six to eight holes affixing to the dust collection holes of the pad. You can purchase such discs with different grit degrees, including low to excellent grades (60 to 220).
It’s possible for you to fit the disc to the plate in one of both manners precisely, hook-and-appearance system (Velcro) and rind-and-stick Pressure Sensitive Adhesive (PSA). Of the two, the most common one is the Velcro one on sanders that are mobile, and you can very quickly get cost efficient discs for the same. Nevertheless, it’s subject to wear and therefore replacement.
It’s possible for you to select a harder or softer plate. A softer one is shining sanding of a curved surface and for sensitive, while a tougher one is for a level surface requiring more sanding capability. Today, nearly all random orbital sanders have a worldwide plate that can sand all standard applications.
Gearbox or the transmission establishes the rate of the tool, which ranges from 1,600 to 26,000 OPMs. The larger this range is; the greater are the abilities of the machine. Thus, it’s greatest to decide on a model with varying rate settings.
Management over its sanding process and the tool mainly determines how smooth the finish will be. The key to a smooth finish is management whose essential facet is varying rate. This setting enables decreasing or growing speed in line with the kind of stuff you’re working on.
Slower speed range is well suited for things like veneer for relieving the chance of sand-through as well as for a soft and smooth finish. Nevertheless, random orbital sanders having varying rates are somewhat more costly than those without it, although that added cost would be worth the management you realize. After all, the liberty to command and correct the speed permits utilizing the tool just as you desire.
It’s reasonable to decide on a sander that can not feel uncomfortable and nonslippery in your hand. Your fingers can quickly wrap the tool across and switch it on or off. At the same time, the tool must not be quite as heavy to hold. A couple of versions include a soft handle layout for giving additional comfort to you. You should make sure that the tool is comfortable hold and to utilize in order which you can use it longer without becoming tired or experiencing cramps.
It’s, in fact, a little tough to judge how a tool will feel in hand. However, there are many variants to check out, like the size and grip strength. Alongside the perfect size, check out on the handle, which helps in relieving both shaking and exhaustion during prolonged work time for a soft finished form.
Random orbit sanders have either a single or double handles. As it delivers comparatively more management while at work, it’s wise to get a version with double handles. You can quickly remove the handle that is next in the event you should work close to a wall. The larger ones can have one or two, although the smaller palm grip sanders handle. You can nevertheless run them with one hand.
Sanding creates lots of dust that could decrease the lifespan of the tool. In the event, you select a version with a sealed switch. Nonetheless, this is just turned. Such a sander also prevents the problems caused while turning the tool on or off due to the collection of dust into the switch region.
If you want to get a corded version, ensure the wire is overly long to get you get an extension cord. So, pick the one with a twine that is long.
Do contemplate having a trigger lock to maintain the tool locked without keeping the gun trigger shoved when it’s in ‘on’ say. Consequently, your hands are at present free for controlling the sander. Another useful attribute to search for is pad brakes that keep gouging away when the substance is greatly notched upon. Also, find a model that permits easy and quick monitoring allowances through screws or knobs.
Overall, this is a great power tool that will make your wood projects more enjoyable. Any activity has its ugly parts, but the random orbital sander eliminates one of the most tedious parts of working with wood. So, if you find yourself involved in such projects, go and buy yourself the best random orbital sander you can find and see for yourself how much more pleasing sanding will become.
