Indispensable to any home and easy to use a sander is a simple power tool, commonly used in woodworking and in some cases metal, to clean, smooth and polish a selected surface. It can bring old furniture back to life and make them look brand new, I even say better than ever. Sanders are available in a multitude of sizes, power and shapes that adapt to any situation but one thing they all share is that all of them, as the name implies, use sand paper. The sand paper used by the machines also comes in various shapes and sizes in order to fit the different sander types and they also vary in how abrasive they are, their grit it can be finer (higher) or rougher (lower) and their usage depends on the particular job youre trying to accomplish.
Choosing a sander can be tricky due to the massive amount of different types, brands and power of these machines. Im here to make this tedious and long process as quick and easy as possible, not only to ensure you make the right choice but that you also get the best deal possible.
There are a few things to consider before buying a sander. First of all, what do you need it for?
Is it a big surface like a wooden floor, medium like a table or small such as a chair or little wooden pieces? Remember to also consider the shape of the objects as well as some sanders are better for curves and round shapes. Power is also very important as some sanders might cave when faced against harder tasks while more potent ones will be able to take them on. Then, the frequency of use.
Will sanding be an occasional event for you, to use when you need to make an old object brand new for example or will you use the sander very often, such as professionally or for a woodworking hobby? Finally, the available space.
Are you short on space and need a compact, easy to store solution or do you have your very own shop or garage that can hold a big and powerful machine like a benchtop sander?
These are the 3 essential questions you should ask yourself before buying a sander, it will make sure you know exactly what you need to satisfy your needs.
As Ive mentioned above, there are a lot of sander types to choose from. They all serve their own purpose, although some can be used for more general work and other for more specific tasks. The most popular types of sanders are:
This type of sander uses a sandpaper belt that continuously loops around the base of the sander. It can be handheld or stationary, the latter being usually accompanied on a workbench with a disc sander as well. A popular, powerful and well rounded choice.
Disc sanders are usually stationary, although you can also find a few reliable handheld machines. They use round, circular shaped sand paper that is attached to a turning wheel. They are great for hard, coarse grit sanding and are also used very much for metal surfaces.
The sheet sanders are handheld machines that use square or rectangular shaped sandpaper that very quickly and repeatedly moves back and forth or vibrates in order to sand a surface. They are usually quite light and versatile, being able to deliver great results with smaller objects and also a bit larger surfaces such as tables.
These machines, also called random orbital sanders, are handheld sanders that vibrate in circles (hence the name orbit), the random variety also spins at the same time. This random orbital fashion is used in an effort to reduce marks and noticeable patterns on the surfaces to ensure the best possible result and finish. It uses disk shaped sandpaper that as Ive mentioned above both moves and spins to create its famous orbital movement.
Spindle sanders, also called oscillating spindle sanders, are the very best when it comes to curve sanding. Simple and effective, this type of sander consists of a tabletop with a protruding sanding drum that not only spins but also moves up and down (oscillates) to ensure the best possible results on curved surfaces. While it takes up a little bit of space it is a must-have if you need to work with curves and its also incredibly useful for a few long surfaces like wooden beams.
I have to admit, these are my favorite sanders. Drum sanders are extremely powerful and effective sanding machines that are mostly used for large surfaces. The machines themselves are quite big but very easy to use you simply insert the piece of wood on the front, it goes through the rotating sanding drums and it comes absolutely clean and smooth on the other side. They save you a whole lot of time and effort, impeccably sanding the pieces almost automatically. Perfect.
Youll also find some more specific ones such as:
Not for any specific task such as the others, it simply means a sander that you can use by placing a single hand on top of it. They are compact and usually very lightweight. A good choice for small and simple tasks.
These are sheet sanders that have a triangle shape on the front in order to sand hard to reach places. They are also called mouse sanders and are very light and small, although incredibly useful. These are inexpensive and can bring another level of professionalism and detail to your pieces.
Lastly you can also find a few sanding machines that offer a combo, such as the famous
As the name suggests, its a larger machine that offers both a belt and a disc sander solution. A very popular choice due to its practicality and very competitive prices.
High-quality in both performance and construction, Jet tools are always elegantly designed and built to last. Their sanders often offer innovative features and top-notch attention to detail while maintaining a competitive price.
This extremely popular brand offers very well-built tools that never disappoint in their power and performance.
Makita is one of my favorite bang-for-your-buck power tool brands, delivering outstanding machinery at astonishing price points. They package potency, performance and durability into excellently thought out sanders.
Known for their elite-tier tools, Festool strives to offer the best although the luxury doesnt always come cheap. Their tools always have a super sleek design and some extraordinary features and are superb tools if you can afford them.
The classic all-rounder, DeWalt offers great tools at a great price and although their tools usually arent ground-breaking, they are always solid, effective and long-lasting.
Dynabrade offers excellent air-powered sanders, every single one Ive owned has a superb design, highly durable body and incredible performance. They are famously known to last for decades and any craftsman will be delighted to hear the name. If you want the best air-tools, Dynabrade is the perfect choice.
Youll often hear me say that Powermatic stays true to their slogan the golden standard in every single machine they have. They deliver, in my opinion, some of the very best sanders in the market in every possible way - tank-like durability, monstrous power, first-rate performance, advanced features and a mind-blowing attention to detail. The praise from the crafts community is well-deserved.
I enjoy Porter-Cable tools immensely, they even produced the Speed-Bloc which is my all-time favorite palm sander. They have great and innovative ideas that come to life in the shape of high-quality and sturdy tools at surprisingly attractive price points.
One of the more mainstream brands of power tools, Black & Decker puts out good products at very decent prices. While they rarely deliver a sander that truly impresses me, they are always solid and very easy to use.
I have a love-hate relationship with Shop Fox, some of the machines Ive tried disappoint me by having a rough finish and lack of quality-control, possibly due to the very discount prices, but sometimes they hit gold and deliver a surprisingly good machine that performs extremely well at super inexpensive prices. Dont worry though, Im here to test them all out first and Ill only recommend to you the ones that pass my demanding quality tests and that are actually worth it.
Not to be confused with Powermatic, Powertec tools are very inexpensive machines that can sometimes lack a bit of quality and attention to detail but still deliver decent results.
Woodtek is known for their expensive products but also their very respected quality in both construction materials and machine performance. Ive never used a Woodtek sander that disappointed although Ive often found other alternatives that offer more bang for the buck.
For some reason, Grizzly and I never got along very well. Ive returned a few of their machines back due to deformities and internal-part issues but some of my woodworking friends swear by the brand and find it to be great. Its very hard for me to find one thats worth the price for the seemingly rough-quality but that wont stop me from testing them and finding out.
Delta combines decent quality with budget prices and brings us sanders that might be lacking when it comes to more advanced features and details but trade that off for stunning price tags.
Ive only started to try WEN machines in the more recent years but I was pleasantly surprised. They give you basic machines for a very very low price which makes them a decent choice for beginners.
Sand Paper Grit
When it comes to picking the right sand paper grit, it all comes down to the wanted results. Lower grits are usually used for the initial sanding process of an object and then an increasingly higher grit is used to get smoother and much more polished results. If you want to remove material quickly like an old coat of paint for example you need a low, coarser grit sand paper such as 20 or 50. For general purposes such as sanding a chair before applying a coat of varnish, 80 to 100 grit is great. For polishing needs, to get things smooth and shiny, you can use from 320 grit sandpaper all the way up to 1000+.
How to Use a Sander
While using a sander is pretty straightforward, there are a few key points and nuances that you should get to know and apply for the best results and maximum safety. First of all, always use the required safety equipment a pair of safety glasses and a dust mask, Ill go more in depth about this below but its always a good idea to protect your eyes and lungs whenever you get to work. I usually sand for quite a lot of time so I also use protective ear muffs or noise cancelling ear buds to avoid the terrible headaches that come with hours of loud noise.
Now that youre ready, in most cases you need to attach your sandpaper piece to your sander.
Different machines have different ways to attach and lock the sandpaper in place. Sheet sanders usually have some sort of clasp where you simply bend the sandpaper below it and then lock it in place. Orbital sanding machines are even easier to ready up since they use Velcro to hold on to the paper. Some machines are different like a belt sander for example, often times they have a lever that you pull in order to relieve the tension pressing the belt down to be able to install a new one. Each machine is different so although they often share the same mechanisms I recommend that you read their leaflet before using them.
When you start up your sander and get to work it is very hard to resist not pressing the machine hard against the surfaces. I know this feeling, and I know its just great to see the surface getting nice and clean so quickly but you have to resist doing this. By pressing the sander with too much force youll actually start leaving scratches and dents on the surface, some are noticeable right away and others only when you apply varnish but they are both easy to avoid. Just remember slow and steady wins the race.
A universal sanding rule is to always sand with the grain (when working on wood). Sanding against the grain will rip out the wood fibers and leave a nasty end result while sanding with the grain ensures a clean and smooth finish.
Finally, remember to keep the surface clean! This is simple but so many people forget it, Ive seen my co-workers take much longer and getting bad results due to not regularly cleaning their objects. Sanders work by abrasion, which needs full contact for it to work properly. By not cleaning often, youll leave dust and bits of wood or metal behind that, even if you dont notice, will get in between your sander and the surface. Keep it clean for the best outcome.
Before any work with a sander I heavily recommend that you equip a pair of safety glasses and a dust mask to prevent any problems with flying debris and breathing in dust. You might not think this is required but trust me, Ive been there and I guarantee that its not a pleasant experience! Imagine for example that youre sanding a surface covered in led paint, without protection you would put yourself in real danger by breathing in the dust, this also applies to any kind of paint. Equipment that you have around the house will do the job just fine but if you dont have any, I recommend these glasses and this mask very cheap and sturdy. For the noise cancelling aspect, that I see as essential, I use these.
Performing regular maintenance on your sander is essential. It will not only guarantee that your machine keeps running in top condition but it also ensures that it keeps doing so for as many years as possible.
The first step is to regularly check the sand paper your machine uses, be it a belt, a disk or a drum it will need to be replaced from time to time due to usage. As soon as it shows signs of wear and tear you should remove it and install a new one to ensure you get the best results on your work.
Your sander should also be cleaned from time to time with either a vacuum or an air compressor to make sure that no bits of wood or dust are clogging up the insides of the machine. This applies even to the sanders that have a collector bag for waste.
Lastly, to ensure your safety, check for any cracks or broken parts on your sanding machine. This can happen with extreme wear or an accidental drop, if you detect any severe cracks or broken parts please get a replacement or, if you can, use the guarantee to get a new one.
Sander Parts & Accessories
For each sander there are various parts and accessories that you can purchase to either upgrade the machine, add a new feature (thinner or larger sanding drums for example) or to replace a worn out part, like sanding pads (the part that holds the paper) instead of buying a whole new machine.
The thing youll be buying and using the most is of course, the sanding paper. You can get these in sheets of your desired shape and of different grits as Ive talked above. Similar to the machines themselves, sand paper is available from a multitude of different brands. Throughout the years Ive grown fond of a few for their performance and outstanding durability, which is a common problem among quite a few brands of sand paper. Ive listed them to help you choose the very best, be sure to check them out here.
