5 Common Mistakes to Avoid with Your Orbital Sander If You Want an Ideal Finish. Orbital grinder

Common Mistakes to Avoid with Your Orbital Sander If You Want an Ideal Finish

When you want to get the best finish on your project, it comes down to the quality of the sanding. Sanding with a random orbital sander or orbital sander (without random pattern) is not complicated, but there are several things to consider in order to avoid common problems, and get the best possible finish. When sanding incorrectly, you can cause swirls, excess dust and other issues that will lead to an uneven or blotchy finish. On the other hand, if you use good technique and avoid the mistakes explored in this article, you’ll have a high-quality finish every time.

Avoid pushing down with too much pressure on the sander.

We all want to finish sanding faster, and get the best cut from the abrasives, so it can be tempting to press down harder with the sander. Intuitively, it seems like that could make the sanding process go more quickly. However, doing this can cause issues like swirls, cut-through, uneven sanding and other problems, such as excess heat and loading. When you use too much pressure, the sander has to do more work to perform its rotations, this means there will be more work for the motor and more friction on the surface of the workpiece. Both of these things lead to more heat. heat can either cause the sander to shut off or potentially lead to pre-mature loading of your sheets or discs.

The rule of thumb for this is to let gravity, or the weight of the sander, and the abrasives, do the work. Each grit is designed to remove a certain amount of material, so if you need to remove more, use a coarser grit, rather than pressing harder. When sanding properly, the sander should move across the surface with ease, as if it were gliding.

Avoid sanding too fast, or too slowly.

Because sanding is often tedious, many people want to finish sooner by moving the sander very quickly on the workpiece. However, like most things where quality and attention to detail are important, moving the sander at a controlled and even pace across the surface will lead to the best results. It’s a bit of a “Goldilocks” issue – going too fast can lead to poor results, with sections not sanded enough or missed entirely, and going too slowly can lead to over-sanding or cut-through in some areas. But, finding that “just right” speed will mean a nice, even sanding job across the entire piece.

Avoid running the sander with RPMs or PSI settings too high or too low.

Whether using an electric or pneumatic sander, having the appropriate sander speed (RPM) for your application will be key in achieving a high-quality finish, and avoiding issues like sanding swirls.

On the pneumatic sanders, the main factors contributing to the RPM is having sufficient air pressure and keeping the machine well lubricated. The pneumatics are designed to run optimally with an air pressure of 90 PSI at the sanding machine, and should be oiled daily, if they are used heavily. (Learn more about tips for caring for your pneumatic sanders and getting the optimal results.) Pneumatic sanders also have a speed controller that will allow the user to speed up and slow down the speed of the machine. Unless you are using the sander on a special application which requires a slower speed, the sander should always be set at the highest speed to avoid swirls.

The electric sanders come with a speed setting option that allows the user to change the power/RPMs. Our other article, Electric Sander Speeds 101, goes into much more detail about the specific options available, as well as the advantages/disadvantages of the various speeds, and the applications for each. For the purposes of this article, suffice it to say that the 10,000 RPM range will be ideal for most woodworking applications, unless very fine control is needed for the application.

Avoid starting the sander in the air prior to sanding and stopping it while still on the work surface.

Said another way: “Start on, Stop off.” This basic technique is critical in helping to avoid creating swirls at the beginning and ending of the sanding session. The reason for this: making contact with the work piece when the sander is already moving will make it more difficult to get a good contact with the surface; and at the end, the stopping the sander while still on the workpiece means the sander will slow down while still in contact, so it will still be sanding your surface during that lag time. This can lead to an uneven sanding job and swirls.

It’s a simple solution. Always remember: “Start on, Stop off.”

Avoid using the sander on an angle.

One of the most common mistakes people make when using a hand sander is using it as if it were an angle grinder – i.e. using the sander on an angle to the work piece, rather than flat on the surface, in order to sand out a problem area in a surface. A disc or sheet sander is NOT an angle grinder and is designed to be used either with a flat sheet/disc directly on the backup pad (for flat surfaces), with a foam interface pad or hook and loop pad saver and conventional abrasives (application varies), or with foam abrasive (like Ekasilk Plus), for finishing on flat, curved or complex profiles.

When using a sander on an angle, you are not resolving the issue, rather you’re creating an area that is sanded more than another area, leading to an uneven surface, and therefore an uneven finish. Additionally, this will lead to destroyed discs/sheets and will cause damage to your backup pad, requiring it to be replaced sooner.

If your surface has irregularities, the best options, depending on the severity of the issues and the type of finish you’ll be using, would be to either switch to a coarser grit and sand the whole surface through the whole grit sequence, or use a filler product to fill in the defects and then sand evenly across the whole surface.

Conclusion

Getting a great finish doesn’t have to be difficult. Following some simple techniques, and using quality abrasives, will help to make the process move efficiently and smoothly. It may seem tedious to slow down and sand through the grits, but the results are definitely worth it, and you’ll be able to see, and feel, the difference.

Choosing a Random-orbit Sander

Rather than juggling with all the different power sanding options on the market now, our author has laid out the options he looks for when buying a new sander.

There are some topics woodworkers can’t seem to agree on: pins first or tails first, shaper or router table, left- or right-tilt. but one thing no one argues about is that sanding is no fun! Random-orbit sanders can reduce the misery of getting your projects silky-smooth. This tool test covers the 5″-diameter class — perfect for home woodworking.

Here are some things to look for when shopping for a new sander and why they’re helpful for better sanding.

Quick-change Artist

Most sanding jobs require working through a variety of sanding grits. The easiest way to make sandpaper disks is with a hook-and-loop attachment system. With hook-and-loop, changing papers is a simple matter of peeling off one piece and applying the next.

If you can work a zipper, you can use hook-and-loop sandpaper. And, provided you haven’t worn out the sandpaper, hook-and-loop enables you to reuse the sheet. All the sanders in this test came with an eight-hole hook-and-loop system.

Variable Speed

The key to a smooth finish is control, and an important aspect of control is variable speed. I often slow a random-orbit sander down when working on veneered materials to reduce the likelihood of sand-through. I also run at a lower speed when using the sander to smooth a finish. Although it adds a bit more cost to the machine, variable speed is well worth having.

Vacuum Options

Every sander in the test came with a dust bag or canister. While onboard collection is better than nothing, what I recommend is connecting your sander to a good quality shop vacuum. This requires a connection on the sander that’s compatible with standard vac nozzle sizes. It’s an option that isn’t offered with every machine. Those that do connect to vacuums will definitely help keep your shop air and lungs cleaner.

Getting a Better Grip

It’s difficult for me to measure how a sander will feel in your hand. Many variables, such as hand size and hand strength, come into play. When possible, go to a retailer that sells the machines you’re interested in and grab hold of them. Check out how easily (or not) your fingers can wrap around the machine and reach the On/Off switch.

There was very little variation in the width of the handgrip on the machines in this test. However, there was variation in the “neck” size under the handgrip where your fingers wrap. Although a number of the testers who helped me — men and women, right- and left-handed — grabbed hold of these machines, we couldn’t collectively come up with an individual machine about which we could all say, “We love this grip.”

Aside from the tool’s grip size, you may appreciate a sander that comes with a soft overmold on the grip. It’ll help reduce vibration and fatigue during those really long sanding sessions.

Love a Long Leash

I love it when manufacturers provide a generous cord on their tools. Some of the sanders here have cords that are 12 or more feet long! My sanders get plugged into a tool-actuated vacuum that lives near my workbench. With a long cord on the machine, I reap the benefit of not needing extension cords, and I’m able to easily get from one end of a big face frame to the other.

Scratching for Answers

When it comes to sanding, the most important issue is how smooth a surface finish the machine can produce. Here’s where the rubber meets the road. Sure, you might periodically use a random-orbit sander equipped with 60- or 80-grit paper to hog off a bunch of material, but more commonly you’re going to use it for finish sanding.

We performed a surface finish test with these machines by equipping each one with a brand-new piece of sandpaper. All the paper was from the same manufacturer and was, of course, the same grit. We then sanded uniformly sized pieces of red oak for a set period of time. Since you typically see sanding scratches when you apply stain, that’s how we evaluated finish quality.

The Festool machines are sure sweet if you’ve got the checkbook for them. Across the board (oak, pine, whatever), my testers called these the smoothest operating machines in the group. The RO125 is a kind of combination grinder/sander, capable of hogging off lots of wood or polishing a high gloss finish.

Among the other test tools, the Bosch and Porter-Cable were close behind Festool for smooth operation. The neck below the handgrip on the Porter-Cable was larger than on other machines, so small hands may have a hard time gripping this tool.

An orbital sander is a type of disc sander. It combines eccentric, planetary motion to the disc’s rotary movement.

These devices smooth a material’s surface to prepare it for subsequent polishing or other treatment (varnish, paint, etc.).

These handheld tools are used on small surfaces. Planetary motion yields an even, more homogeneous surface finish. The discs are made of abrasive paper with grits of varying size for gradual reduction of surface roughness. One can find both electric and pneumatic orbital sanders. Some models include a dust-suction mechanism.

How to choose

The main choice is power source: electric or pneumatic. Otherwise, all models operate similarly. Abrasive paper is selected as a function of the type of surface to be sanded.

Easiest To Use: Milwaukee M18 Random Orbit Sander

The Milwaukee M18 Random Orbit Sander is an incredibly maneuverable orbital sander, as it’s cordless and weighs just 2.0 lbs. This sander features a variable speed control dial that allows users to choose from six different speed settings, ranging between 7,000 and 12,000 OPM. This ultimately means users are in more control over orbit speed and can more accurately match speed to their application.

Although the Milwaukee M18 is considered a random orbit sander by name, it’s actually a palm sander. This is due to the fact that by definition, a palm sander is smaller and more lightweight than a random orbital sander – which tend to be much larger tools. This battery-powered portable power sander may be small, but it’s surprisingly powerful and effective.

Key Features

  • Cost: About 110
  • Power source : Cordless
  • Weight : 2.0 lbs.
  • Dimensions : 6.0 by 11.0 by 7.0 in.

Our Experience

As the only cordless option featured in this review, our team of experts named the Milwaukee M18 the Easiest to Use orbital sander on the market.

Speed : While this palm sander utilizes a basic lithium-ion battery with a runtime of roughly 35 minutes, it’s much more powerful than you’d expect. Able to operate between 7,000 and 12,000 OPM, we appreciated the fact that this sander has variable speed control.

Maneuverability : The Milwaukee M18 is easily the most maneuverable orbital sander we researched or tested. We love how lightweight this sander is, especially for its level of power output. However, ease of use could be improved upon if there were more grip options.

Versatility : The Milwaukee M18 was surprisingly versatile, and our team members were able to complete most of the buffing process with this power tool. However, we do wish this palm sander could orbit at slightly slower speeds for some stages of the buffing process.

What Customers Are Saying

Amazon Review Score: 4.7 out of 5 based on over 2,500 ratings

This orbital sander is described by reviewers as compact and powerful. Although most seem to use this cordless orbital polisher for sanding, many also use it for auto body work. One of the biggest issues with this sander, according to reviews, is the battery life. The M18 batteries that power this sander drain very quickly.

  • Weight : 3.2 lbs.
  • Dimensions : 7.0 by 5.0 by 6.0 in.

Our Experience

Although the Black Decker 5-Inch Random Orbital Sander isn’t expensive or dubbed as a high-end option, it’s easily one of the best random orbital sanders on the market.

Speed : As users are unable to vary the speed of the Black Decker sander, it received a low score compared to the rest of the sanders and polishers in this review. However, we were impressed with the fact that this sander could operate at 12,000 OPM.

Maneuverability : Due to the Black Decker ’s incredibly light weight and slim design, it’s highly maneuverable. Although this is a corded sander, as long as you have an extension cord you’ll have no issues moving this power tool around.

Versatility : Because this sander only operates at one speed, specifically 12,000 OPM, it means the sander isn’t as versatile as we would like. This power tool will be great for removing paint from your car, but won’t be able to effectively perform more delicate stages of the buffing process.

What Customers Are Saying

The majority of reviews refer to the Black Decker as a great little sander, while several reviewers note how impressed they were with the dust collector bag. One reviewer claims she’s abused this sander for three years now and it still works incredibly well.

While this sander is good for beginners, it isn’t especially powerful and some find the handle uncomfortable.

Orbital Sanders And Orbital Polishers Buyers Guide

While this article focuses on orbital sanders, it also highlights some of the best random orbital polishers on the market. Both types of devices will work for buffing out your car or general DIY car detailing, but some are better suited for other applications.

Differences In Tools

  • Random orbital sander : This sander is a handheld power sander that rotates in elliptical cycles known as orbits.
  • Orbital sander : Similar to a random orbital sander in almost every sense, this type of sander moves in circular rotations rather than simultaneously moving back and forth as a random orbital sander would.
  • Palm sander : Otherwise known as a 1/4-inch sheet sander due to its size, this is the smallest and most compact type of sander. Palm sanders are also usually square in shape.
  • Random orbital polisher : A sort of combination between orbital and rotary polishers, this polisher moves in an orbital motion in the same manner as that of a random orbital sander.
  • Orbital polisher : This type of polisher moves in circular rotations, rather than orbits, and tends to be the most common type of polisher.
  • Rotary polisher : Simple in concept but more difficult to master and control than random orbital polishers, this type of polisher spins in a circular motion and creates a lot of heat and friction, which can potentially damage a car’s paint.
  • Dual-action polisher : Also referred to as a forced rotation polisher, this polisher combines the movement of rotary and random orbital polisher by forcing rotational movement along with orbital motion.

Recommended Speeds

If you don’t use your sander or polisher at the proper speed for your desired application, then you might not get the results on your car that you were looking for.

  • For compounding. we recommend operating your polisher or sander between 1,750 and 2,400 RPM.
  • For polishing. we recommend operating your sander or polisher between 1,200 and 1,750 RPM.
  • For heavy cutting. we recommend operating your polisher or sander between 2,000 and 2,500 RPM.

RPMs and OPMs should not be confused, as they are two completely different motions and measurements. While there’s no guide to converting RPM to OPM, or vice versa, we can provide a rough guide for recommended OPMs for different stages of the car buffing process.

  • For waxing and buffing. we recommend operating your polisher or sander between 1,500 and 3,500 OPM.
  • For polishing and cleaning. we recommend operating your sander or polisher between 2,500 and 4,000 OPM.
  • For removing paint defects and oxidation. we recommend operating your polisher or sander between 4,000 and 7,000 OPM.

Variable Speed Settings

While many of the top sanders and polishers in the industry feature variable speed settings, they aren’t all made the same. Most sanders or polishers that have variable speed settings typically have six settings to choose from.

There isn’t a standardized OPM or RPM that correlates with a specific speed setting number for sanders or polishers. This means that you should read your user manual and any available literature on the subject, so you don’t accidentally select a speed setting that won’t provide you with the results you are looking for.

Orbital Sanders: Bottom Line

Although they require a skilled hand, orbital sanders are great for adding a smooth finish to a vehicle’s body panels and can be used for other DIY tasks like woodworking. We like the Milwaukee M18 Random Orbit Sander for a few reasons. This cordless sander has a comfortable grip and powerful motor, but customers seeking a variable-speed sander may want to explore other options.

Orbital Sander: FAQ

What is the best orbital sander on the market?

According to our in-depth product testing, the best orbital sander on the market is the Milwaukee M18 Random Orbit Sander. This is because it’s reasonably priced, easy to use, and surprisingly powerful.

Which is better, an orbital sander or a random orbital sander?

Orbital sanders are older, less expensive, and simpler than random orbital sanders. Orbital sanders are square in shape, which makes getting the sander in nooks and crannies easier, but random orbital sanders usually have variable speed switches.

What’s the difference between a rotary polisher and an orbital polisher?

Random orbital polishers are a combination of rotary polishers and orbital polishers. The speed of random orbital polishers is noted in orbits per minute (OPM), as the orbital polisher orbits rather than rotates. On the other hand, a rotary simply spins.

Definition of an Orbital Sander

Orbital sanders are hand-held tools that work by rotating themselves elliptically to create a smooth surface. You can even use them to remove rust or paint. If you need a smooth surface in a short time, an orbital sander might be your best bet.

Applications for Orbital Sanders

What is an orbital sander used for? There are many different applications, like:

  • Furniture making: You do not have to be a professional to use an orbital sander on furniture. Random orbital sanders are great for wood furniture because they won’t leave elliptical-shaped streaks in the wood. Whether you are making furniture or refurbishing it, orbital sanders can give your furniture the smooth surfaces they will need for staining or painting.
  • Cabinetry making: Cabinet making and furniture making differ in their needs and demands. This difference comes into play because cabinet making involves more built-in and interlocking components. Orbital sanders are perfect for smoothing out the joints on a cabinet.
  • Staircase building: Orbital sanders are a must-have when it comes to building staircases, where smoothness and speed are vital.
  • Toy manufacturing: Orbital sanders are great for making wood, plastic or metal toys. Just make sure you get the proper size of sander for the toy you are making.
  • Removing rust or paint: Many refurbishment projects require the removal of rust or paint. Orbital sanders can help you there since it’s among their more common applications. DIYers often need an orbital sander to prep surfaces for painting by removing rust or existing paint.
  • Refinishing hardwood floors: An orbital sander simplifies t he process of refinishing hardwood floors immensely. The appropriate grit sandpaper lets you remove surface scratches or old finish. You can then use finer grit as you continue working, smoothing the floor further as you go.

How to Use an Orbital Sander

In general, there are some things to keep in mind before you start your project. It is best to apply even pressure across the pad of an orbital sander. This ensures there will be no divots and swirls on the flat surface you are working on.

Before you begin working with an orbital sander, be sure to wear a dust mask and protective glasses to keep yourself safe. Work in a well-ventilated area, and remember to empty your sander’s dust bag before using it.

Now, let’s take a look at how an orbital sander works in action.

Choose the Sandpaper

Deciding which sandpaper will work best for your project is the first step to using your orbital sander. Different sandpapers have different levels of grit. The higher a sandpaper’s grit, the finer the grain particles and vice versa. Consider varying levels of grit for sandpaper to get the right product for your job:

  • Extra fine: Extra fine sandpaper typically has a grit of 320-400. You can use this sandpaper to sand between coats of finish.
  • Fine: Fine sandpaper has a grit of 180-220. Use this sandpaper if you are going to apply stain, paint or finish after using the orbital sander.
  • Medium: Medium sandpaper has a grit level of 120-150. If you are removing paint or stain from a surface, consider using this sandpaper.
  • Coarse: Coarse sandpaper has the lowest grit at 60-80. Use this sandpaper on rough surfaces.

Load the Sandpaper

The next step of using an orbital sander would be to load the sandpaper into it. Your sander may use a hook and loop system to peel off and replace sandpaper, or your sander may also use sensitive adhesive. Load the sandpaper onto the base of your sander while making sure you align your sandpaper with the base and dust removal holes of your sander.

Test the Sander

Turn your sander on and do a test to make sure it is working correctly. Grab a piece of scrap wood, metal or plastic and move your sander across it in a circular motion. Ensure the sandpaper is secure and you see the results you need based on the grit you selected.

Sand Your Surface

The last step in using your orbital sander is to do some sanding. You can sand in any motion, so work with the material you are using in the direction that’s best for it. To make sure your sander does not cause scratches, check your sandpaper periodically. There may be old finish or dust built up on it.

You can use the edge of your sander, but it is a good idea to keep the entire disk of it on the surface of what you are sanding. You’ll be left with a smoother surface because the sander’s power will distribute evenly over the whole disk. After using your sander, you should see a smooth and clean finish to your surface.

Can You Use an Orbital Sander on Wood and Metal?

The good news is, you can use an orbital sander on both wood and metal.

Wood

Orbital sanders are an excellent tool to sand wood with. They remove wood at an astounding rate and leave surfaces gleaming as a fine finishing sander would.

There are different types of orbital sanders, such as regular orbital finishing sanders and random orbital sanders. Regular orbital sanders move in the same orbiting pattern over and over. Random orbital sanders move in a non-predictable pattern, leading to fewer scratch marks on wood than regular orbital sanders.

Random orbital sanders come in handy when you are working on the stocky legs of furniture or the flat panels of cabinets.

Metal

Can you use an orbital sander on metal? Absolutely! Random orbital sanders with speed-reducing systems are often the best sanders to use on metal. Follow these steps to sand metal with a random orbital sander:

  • Step 1: Start sanding with 80 grit sandpaper. If you are using a random orbital sander, make sure you have it set to a low-speed setting first. Too much speed can make it difficult to produce the desired results. Sand the metal in the same direction each time. Stop sanding when your metal surface is shiny.
  • Step 2: Next, change the sandpaper to a sheet with 200 grit. Sandpaper with high numbers of grit like this works better on densely spaced grains. Sand your metal with this sandpaper attached to your orbital sander, and you’ll soon have the smooth metal surface you desire.
  • Step 3: Use stand-alone sandpaper to finish up corners or places your sander could not reach, especially if you notice any leftover rust or paint.
  • Step 4: Use steel wool to finish the process. If there are any swirling marks on your surface, the steel wool will get rid of them.

How Much Does an Orbital Sander Cost?

Orbital sanders range in price depending on where you purchase them and other factors, but let’s look at some from our store here at Construction Fasteners and Tools. Our orbital sanders range from 75-600. One of the primary differentiators of cost in an orbital sander is whether it has a cord. While it won’t always make a huge difference, you can generally expect corded sanders to be the more affordable of the two.

Cordless

A cordless orbital sander offers excellent maneuverability. There’s no need to angle yourself around your project or continuously move the surface within reach of a short cable. Many remote construction sites benefit from cordless tools because there’s no need to plug into a limited power supply, such as a generator.

With cordless designs, you’ll need to consider the runtime of your projects. Depending on your settings, many cordless sanders can run from 30 minutes to an hour. If you usually sand for longer than that, pay special attention to this specification. You may need to pay more for a sander with a particularly long runtime. Factor in the price of additional batteries, too, if you plan to have backups.

For reference, two of our popular cordless sanders, the Milwaukee Tool 2648-20 and the DeWALT DCW210B, currently run for under 150 each. They both offer long runtimes, ergonomic designs and variable speeds up to 12,000 orbits per minute (OPM).

Corded

Corded orbital sanders may tether you to an outlet, but they’re great for projects that you know will take a while because you won’t need to worry about runtime. Since there’s no need for a heavy battery, corded sanders are lighter and may be easier to handle. They’re usually more affordable than cordless sanders.

The DeWALT DWE6423K and Makita BO5030 sanders both offer similar orbits per minute as the cordless options we mentioned above but cost just under 100. Plus, you won’t need any extra batteries.
